There are several options for the ratio of fuel and lubricant. As a rule, this number ranges from 20 to 50 ml of oil per 1 liter of gasoline.
Again, you must follow the instructions for the product or the recommendations indicated on the oil label (priority of the instruction). In the absence of such, before diluting gasoline, you need to pay attention to the power indicator of the product, since the created proportion directly depends on it.
- Up to 1.5 kW, the recommended ratio is 25 ml of oil per 1 liter of gasoline;
- Above 1.5 kW 20ml / L.
In gasoline for a chainsaw, it is allowed to add oil a little more than the recommended proportions (up to 5 ml per 1 liter). In this case, you should be extremely careful, because non-observance of the proportions can lead to breakdown, and as a result, expensive repairs.
If you dilute gasoline with a large volume of oil, then during operation the number of shock loads on the cylinder-piston system will be increased, and carbon deposits may also form, as a result of which the CHP will fail.
The addition of a small amount of oil to gasoline for a chainsaw can lead to insufficient lubrication of the surfaces of moving elements, which will lead to additional friction of the elements and their heating, followed by the destruction of the entire mechanism.
How to dilute gasoline with chainsaw oil
The surest solution is to follow the recommendations specified in the instructions for the product! In the absence of such an opportunity, you can use a special fuel preparation formula.
According to experts, it is necessary to use unleaded fuel with an octane rating exceeding 90. Gasoline A92 and Ai92 is considered ideal. You can use the 95th, but there is an opinion that it is better to refrain from this kind of gasoline, since some of them are made on the basis of the 92nd with the addition of additives. The latter, in turn, are harmless for 4-stroke car engines, but they will be superfluous for the “sensitive” mechanisms of 2-stroke motors.
It is recommended to use fresh gasoline for chainsaws, since when stored in cans the fuel can lose its octane properties.
If you want the tool to do its job perfectly and last for more than one year, you must provide it with fuel and lubricant of the proper quality.
According to the international classification, oils of the following markings are used for chainsaws:
- Use oil for 2-stroke engines only;
- Do not use the material after the expiration date;
- It is strictly forbidden to add working off (it contains many unnecessary impurities. harmful to the central mechanism of the chainsaw);
- You can not use chain lubricant (for each device: chain and engine. it is its own);
- It is preferable to use synthetics or semi-synthetics (during development, it almost does not form combustion products, but the price of such material is higher than that of mineral oils).
Not only the quality and proportion of fuels and lubricants is important (although it is dominant in this matter), but where and how (how) gasoline is diluted with oil for chainsaws.
The technology provides for the use of containers with graduated divisions, some brands (along with chainsaws and oil) produce containers for mixing and storing fuel. Made of a special non-combustible material, they are produced in the form of a canister or bottle, often endowed with measuring lines, and some of them have two entrances (separate for each type of fuel and lubricants).
Often, improvised means are used for mixing:
- Plastic / glass bottles;
- Syringe (no needle);
- Measuring cups;
When using household products, be extremely careful, because during the mixing process, when combustible material interacts with the surface of non-specialized containers, static electricity can be generated. this is fraught with an explosion. When making a mixture, oil is added to gasoline, since it has a higher density.
A new chainsaw immediately after purchase has a slightly lower performance than similar models that have been in operation. The rated power of the engine is reached only after 6-10 full tanks of the fuel mixture have been used up.
However, it should be noted that running in an imported chainsaw (Husqvarna, STIHL, Partner) has significant differences over domestic chainsaws. So, for example, it is not necessary to develop several tanks of the fuel mixture at idle speed. Running-in consists of cyclic work with a minimum load on the motor: first, the sawing of soft wood is carried out for 1-2 minutes, then 20-30 seconds of idling. This prevents the formation of a large layer of burn-on that occurs during prolonged operation of the chainsaw at idle speed.
Chainsaw break-in must be carried out on high-quality AI-92 gasoline without any additives and branded oil, which is recommended by a specific manufacturer. You can find out what and how much oil you need to fill in gasoline for a chainsaw in the instructions for the chainsaw itself.
In no case should products intended for low-speed engines be diluted with gasoline, as in the photo.
The proportion of oil and gasoline for a chainsaw of the corresponding brand:
- STIHL with power less than 1.5 kW. (1:40);
- STIHL with a power of more than 1.5 kW. (1:50);
- Partner. (1:33);
- Husqvarna with power less than 1.5 kW. (1:40);
- Husqvarna with a power of more than 1.5 kW. (1:50);
- Jonsered. (1:33).
The prepared mixture can be stored for up to two months, and then there is a risk of engine breakdown due to the inevitable decrease in the octane number of gasoline.
Application in practice
From all of the above, it is worth noting that it is necessary to choose a two-stroke oil responsibly. The main task before pouring lubricant into the motor is to study the operating instructions. If the manufacturer allows the use of different oils, then you can fill in mineral water or more expensive synthetics.
Before infusing, make sure the lubricant meets the recommended standards. In practice, the difference between synthetics and mineral water will be negligible. But still, on synthetics, the engine can start a little better, and wear less at high speeds. There can be less carbon and coke in the combustion chamber.
But if the instructions indicate that it is worth pouring in only certain synthetics, then in no case should mineral water be used, even if it is of the same standard. In such a situation, for a number of important parameters, mineral oil is still not suitable. And all due to the fact that the lubrication system of the motor for the use of oils with a mineral base is not designed.
It served for a long time and did not cause problems with repairs, you need to properly prepare the fuel mixture. Internet forums are replete with questions on this topic. We interviewed experts and compiled a short guide.
To prepare the fuel mixture, use AI-92 or AI-95 gasoline. A lower octane number will not work. Gasoline is not necessarily leaded (otherwise the engine will fail) and not old (octane number can change over time). It is forbidden to use oil for boats and four-stroke engines.
The main issue is proportions. Excess oil will cause carbon deposits on pistons and spark plugs. Excessive gasoline will cause piston seizure and early engine failure. On average, one liter of gasoline is mixed with 20-50 ml of oil. STIHL and Husqvarna, for example, recommend taking 100 ml of oil for 4 liters of gasoline. The specified proportion is optimal for chainsaws up to 1.5 kW. For chainsaws over 1.5 kW of the same brands, use a ratio of 1/50 (100 ml of oil per 5 liters of gasoline). Recommendations from Partner and Jonsered: 1/33 ratio (3.3 liters of gasoline, 100 ml of oil). The supersynthetic oil is added at a rate of 100/1. These figures are approximate. Always use the data given in the instructions for your particular chainsaw model. Trust the numbers on oil labels to a lesser extent.
What to mix? On sale are canisters with graduated marks and two holes. for oil and gasoline. Pour in ingredients, screw on lids and stir by tilting the bowl.
Many people use glass and plastic bottles, baby horns and syringes. Be careful with glass and plastic for static electricity. Make sure that no solid particles or water droplets get into the mixture. Be sure to stir the mixture thoroughly.
Finished fuel cannot be stored for more than 25-30 days, because the oxidation process changes its composition. Engine breakdown caused by overexposed fuel is considered non-warranty. The amount of repairs reaches 80% of the cost of a new chainsaw. After the end of the working season, use up the remaining fuel, turn off the engine, remove the remaining fuel mixture.
Remember, your goal is to create a mixture that will ensure smooth operation of the engine, complete combustion of fuel without the formation of deposits, smoke or scuffing.
Two-stroke engines, despite their imperfection in relation to four-stroke designs, are still massively used on many newly produced devices.
Legendary Java with 2-stroke 638 engine
- Basically motors of this type are used for:
- small volume motorcycles, snowmobiles, mopeds;
- lawn mowers, motoblocks, portable generators, chainsaws;
- motor boats;
- other devices where small size is required with high power.
The device of this engine imposes some features on operation. In particular, the usual lubrication system on most two-stroke ICE designs is absent.
There are modifications where the lubricant is fed directly into the flow of the fuel-air mixture from a special device in the form of oil mist. However, the vast majority of oil for modern 2-stroke engines enters the cylinders along with the fuel.
Recommendations and tips for choosing
You can see that on the modern market there is a large assortment of oils for boat and other 2-stroke engines. You can also find ready-made products in which the oil is already diluted and ready for use. To do this, it is poured into a fuel canister, mixed well and poured into the equipment tank.
In terms of properties and prices, products can vary greatly. Synthetic oil is more expensive than mineral oil. It is because of this that difficulties arise when buying. It is worth noting that, first of all, it is necessary to focus on the information specified by the engine manufacturer when choosing.
If it is said that the oil of the TC-W3 standard should be poured into the equipment, then any one that corresponds to this standard will do. In this case, it does not matter that it is synthetic or mineral water. You need to choose brands with a good reputation and beware of counterfeits.
If the instructions for use contain separate recommendations for oils, then it is strictly forbidden to inject other types of lubricants.
The thing is that initially the engine was designed only to work with the specified material, and if you start using other lubricants, this will quickly lead to the unit leaving the operating state. Simple equipment, especially made in the USSR, can work successfully on the MS-20. But an imported motor can coke up and stop working after a few hours.
It is strictly forbidden to pour two-stroke diesel or automobile gasoline oils into engines, and even more so, “working off”. Such lubricants contain a large amount of additives, and when burned, they form a lot of ash. It is worth considering that if you ignore all these rules, then not only imported, but also domestic equipment, which is distinguished by its endurance, will soon break down.
Is it possible to pour 95th gasoline into a chainsaw?
This question is most often encountered by novice users of chainsaws. Quite often, they buy 95th gasoline instead of the 92nd recommended by the manufacturer, considering that the higher the octane number, the better the fuel quality.
In fact, this is not the case. The fact is that fuel of the 95th grade in its quality is sometimes not only not superior, but also significantly inferior to the 92nd gasoline. This is due to the fact that the composition of the AI-95 fuel is quite often “catching up” due to the introduction of various additives to it, designed to increase the octane number of gasoline.
In this regard, it is best to use gasoline exclusively of the AI-92 brand for refueling the chainsaw. This will make it possible to prevent serious damage to the chainsaw mechanisms and improve its performance in difficult operating conditions.
How to choose for a lawn mower?
For two-stroke engines, brushcutters use AI-92 or AI-95 gasoline. Most often. the first of the named. There is always information about this in the technical data sheet of the product. If, for some reason, it is not known exactly on what gasoline the grass trimmer should work, you can pick it up by testing both brands of gasoline in action. Global changes in the engine will not happen from this, and it is quite possible to determine what kind of gasoline this or that model of the unit “loves” more, according to some factors. This will be shown by the developed power, and throttle response, and engine heating, as well as its stable operation at all speeds.
But it is much more difficult to determine the proportions of oil to a certain volume of gasoline. In this case, you need to know at least something about the manufacturer of the equipment. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.
For example, for Chinese low-power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for mineral oils, and the second is for synthetic oils. We have already talked about the choice of standard proportions for petrol cutters of European and American manufacturers in connection with the type of oil. According to the class of oils for household trimmers, you need to use TV oil according to the API classification. For more powerful. class TS.
For information on the ratio of gasoline and oil needed for a lawn mower, see the next video.
Two-stroke oil is a separate lubricant for internal combustion engines. These lubricants differ from others in their properties. As already noted, special requirements are imposed on two-stroke oils.
For gasoline 2-stroke engines, oils must necessarily have the following qualities.
- The minimum amount of ash and coke that forms in the cylinder during combustion. The lubricant, ideally, should completely burn out.
- It should dissolve easily and completely in the fuel.
- The lubricant must have lubricating, antiwear, protective properties at elevated temperatures. And it should also protect well against corrosion.
If the lubrication system is separate, then it is necessary that the oil remains fluid and well pumped. If we take into account the scope and specificity of 2-stroke engines, which serve as motors for scooters and mopeds, engines for lawn mowers, boat motors and others, then separate requirements are imposed on the toxicity of the material.
If the lubricant gets on the soil, then it must be as safe as possible for the environment, and when it gets into water, it must decompose very quickly.
Such oils must comply with TC-W3 and 2 T standards. Very often they can be distinguished from analogues by their color, as they are additionally colored. They are mostly blue. Even when mixed with gasoline, it is clearly visible.
According to the 2 T standard, such lubricants are used in air-cooled engines ranging from lawn mowers and chainsaws to motorcycles (light). But for use in outboard motors with water cooling and jet skis, TC-W3 oils are designed.
There are low-viscosity oils for winter operation. Lubricants can be based on the following:
Features of running in a new tool
This concept includes the gentle operation of the chainsaw at the initial stage of its operation. The technology also provides for the operation of the engine on a mixture with an engine oil increased by 20%.
The running-in time in engine hours is indicated in the attached instructions. In practice, for the tool to reach the working level, it is enough to generate 3-5 refills of the saw’s gas tank.
New models do not need running-in, but the first hours of operation are not recommended for the chainsaw to be used with heavy loads.
Gasoline with chainsaw oil. how to dilute and why it is done
Chainsaws from different companies are based on a two-stroke internal combustion engine that drives the cutting headset of the tool. To drive the internal combustion engine, the proportions of gasoline with chainsaw oil are used. Combining gasoline with oil is a mandatory procedure, so if you just bought a tool, then you need to understand the peculiarities of refueling it.
Chainsaw refueling instructions
Knowing the ratio of the preparation of the petrol-oil mixture, you can start refueling it. Refueling instructions are as follows:
- First you need to prepare the mixture. Having combined the two main components, you should mix them thoroughly.
- Place the tool on a clean and level surface. Before unscrewing the gas tank cap, it is necessary to clean or blow off sawdust, dust and dirt.
- The filler neck must point upwards.
- Install a small watering can in the neck, then pour fuel
- Control the refueling process, as the volume of the tank is small, so it fills up quickly
- Do not fill up to the full maximum, since when the tank cap is closed, the remaining fuel will splash out.
- After the fuel is poured into the tank, immediately add chain lubricant.
- Fuel consumption and chain lubrication are approximately the same, therefore both tanks must be filled at the same time.
- After refueling, you can start starting the engine.
It is better to start the engine not in the place where the refueling was carried out, but to move to a distance of 2-3 m. The tool is ready for work, and you can start to start it. How the chainsaw engine starts, you can read in this material (link).
How to dilute gasoline with chainsaw oil
The chainsaw is used when cutting trees, in repair work. The popularity of this tool is growing every year. Each owner buys it for his own house. However, in order to use it for a long time, it is necessary to properly care for the instrument. Only with good care will the saw serve a long life and will not harm your health.
This is especially true in a gasoline-oil mixture. It must be diluted and poured strictly according to the instructions that will be given below.
The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. Consumables with expired storage, made on the basis of gas condensate, which have water and mechanical impurities in their volume, are not suitable for the preparation of fuel.
- The opinions of experts on the use of gasoline of different brands are ambiguous. On the one hand, the incomplete compliance of domestic gasoline A-92 with European standards is recognized.
- On the other hand, the quality of A-95 gasoline is questioned due to the high content of anti-knock additives. It is possible to use this fuel for the preparation of fuel for a chainsaw only with full confidence in its quality.
- The difficulty lies in the presence of various improving additives, with the help of which unscrupulous manufacturers and distributors increase the performance properties of motor gasoline with a lower octane index.
Also, irreversible changes in the working properties of the fuel occur when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance.
A large assortment allows you to choose oil that fully corresponds to the class and characteristics of the chainsaw, the conditions of its subsequent operation.
- For budget models, you can use oils of the Standard category, for professional chainsaws, consumable lubricants of the Super and Ultra categories are recommended.
- To prepare a full-fledged fuel mixture for a chainsaw, it is advisable to use branded oils or their branded counterparts recommended by the operating instructions. In particular, STIHL and Husqvarna engine oils of the same composition and application are completely interchangeable.
Experts recommend that owners of chainsaws exclude from the scope of attention motor oils intended for two-stroke engines of mopeds, boat motors and other mechanized household appliances.
The power units of this equipment operate in more comfortable conditions, which makes the requirements for their operational characteristics less stringent.
How to dilute the components of the mixture
As mentioned above, gasoline with oil should be diluted in a specially prepared container. Do not do this in a gas tank. The latest technology will cause some of the oil to enter the carburetor. As a result, you will have to disassemble the engine and wash it.
Standard dilution ratios are 50: 1 and 40: 1. Such a mixture will not interfere with the combustion of gasoline in the gas tank and will improve the lubrication of the rubbing parts of the mechanism. When running in a new tool, it is advisable to add twenty percent more lubricant. It is recommended to dilute with a large amount of oil in areas with high air temperatures.
Many owners will be interested in information on how to dilute gasoline with oil if there is no measuring container. A twenty cc medical syringe is suitable for this. Although most often measuring containers are included in the kit for chainsaws.
The neck of the gas tank must be cleaned and degreased before diluting the fuel. It is advisable to pour it through a filter. Any rag will serve as a filter.
After use, the remaining mixture must be drained and disposed of. Remember it’s better to overfill than underfill. What will happen if you do not take into account the recommendations, read below.
If you do not follow the instructions, you can render the tool inoperative. For example, if the fuel is not diluted, then carbon deposits will form more often, the necessary lubrication of the pistons will not occur, as a result of which the temperature in the engine will rise. This will cause the pistons to break. Or the owner of the saw will inhale large quantities of toxic fumes throughout the entire operation. Thus, he will earn health problems, break the instrument.
If you use poor quality lubricants and fuels, they can also damage the engine. It is not recommended to dilute engine oil made for automobiles. Fuel must be purchased with a high octane rating.
Which fuel to choose for a chainsaw is a non-idle question, the success of the unit directly depends on it. According to the existing canons, good gasoline for a chainsaw is considered not leaded, but high-octane from a trusted manufacturer. The cleaner the fuel, the better. If gasoline has been stored in a canister for a year or a year and a half, this will adversely affect the nature of the device’s operation, therefore, the substance should be prepared before starting work.
It is important to monitor that there is no alcohol in the fuel, any additives that can disrupt the functioning of the power plant. Experts are still debating which is better than 95 or 92. The first has more stable detonation indicators, but most often the 92nd is still used. The reason is simple: questions often arise by the 95th, it contains a large number of various additives that have a bad effect on the operation of the saw engine. Micro-knock occurs (piston impulse in the opposite direction), which occurs practically at every revolution of the crankshaft. If the octane number is even higher (98), then the micro impacts will become even more intense.
The consequences of improper gasoline on the quality of the unit can only be negative:
How To: Mix Oil/petrol 25:1 ep1 s1
- The mechanism will be difficult to start.
- Parts will wear more intensively.
Advantages and disadvantages of oil
Any quality machine oil has its pros and cons.
Any quality lube has its pros and cons. Some experts say that any chainsaw oil will work. This is not entirely true, almost any substance can be used for the Hurstavna chainsaw, but only transmission oil is required for the STIHL chainsaw. When choosing, you need to know the color of the oil well, a two-stroke engine requires a composition that has a reddish, bluish or greenish tint.
To prepare the mixture yourself, you need to use a heat-resistant lubricant, which has a well-known brand name.
Seasonality affects the density of the product:
- Air temperature.
- Solar radiation intensity.
What are the features of different oils, you can find out precisely by carefully studying the label on the container. In the absence of instructions or labels on the packaging, you should refuse to use such a substance. At the same time, the performance characteristics of the oils should not change dramatically with a difference in temperature conditions.
You should not use any substitutes, often there are counterfeit products among them (up to 20%). It is quite difficult to distinguish a fake, you need to have special equipment.
It is recommended to store fuel in metal containers. It is best to prepare the fuel mixture in a canister.
There are a large number of oils and each has its own characteristics.
The consistency is done in the ratio:
The performance characteristics of mineral or organic oils intended for the chain itself are not suitable for preparing the fuel mixture. The finished product is poured into the tank (up to half), then mixed (the container must be hermetically closed). Thus, a homogeneous composition is obtained. It is better not to prepare fuel ahead of time, it loses its functional properties quickly enough. At room temperature, flammable liquid deteriorates within two weeks.
The highest quality product is considered to be the product of Husqvarna, followed by Lukoil machine oil.
- Low consumption.
- Maintaining quality.
- Ability to maintain technological qualities for a long time.
- Can work in extreme conditions.
- No toxins.
- The minimum amount of carbon deposits.
Many professional tools use a lubricant made using API-TB technology (USA). Products made according to the JASO-FB method (Japan) are also popular.
It is permissible to mix oils from different brand manufacturers with similar characteristics. Mineral and synthetic oils are incompatible. The best oil for household chainsaws is considered “Standard”, for professional equipment the technical fluid “Ultra” is optimal.
Some oils can successfully replace each other. For example, substances produced by Husqvarna and STIHL. Lubricant for scooter engines or motor boats is not suitable for chainsaws, the oil quality in them is low. If the proportions of oil and gasoline are not maintained, then the tool will quickly fail due to the abundant formation of carbon deposits.
What gasoline should you use for your chainsaw? How to breed it correctly?
The chainsaw is simple to operate and is sometimes needed in a private household. The device cannot work fully if you do not use the correct fuel mixture, which you should be able to prepare.
Each chainsaw has different technical data and can do different jobs.
To make fuel mixture huyosen chainsaw
Powerful saws are suitable for felling centuries-old trees, small-format chainsaws are more suitable for various tasks in the home garden:
Chainsaw standard blocks:
- Power point.
- Ignition unit.
- Fuel block (oil and fuel tank).
- Filters for cleaning incoming air.
- Chain brake.
- Tension mechanism.
- Chain lubrication element.
Each chainsaw requires high-quality fuels and lubricants, it is they that ensure long-term productive operation of the unit. What gasoline for the chainsaw to fill, in what proportions?
For domestic chainsaws, simple oils are suitable, foreign chainsaws need more complex fuel mixtures that have been thoroughly cleaned.
How much oil is required to add to gasoline?
Types of oils used for dilution in gasoline
Chainsaws do not have oil pumps, so combustible mixture alone cannot be used. You should carefully read the instructions that are attached by the manufacturer to each product. There is a lot of information on the Internet, it is not difficult to find it.
If there is no lubrication, the saw will fail after a short time. It is recommended to do preventive maintenance of the unit, fill in properly diluted fuel, in this case the tool will function for many years.
If you take, for example, a Husqvarna chainsaw, then unleaded gasoline with the first addition of grade 92 is suitable. If the composition has a greenish color, this indicates that the product is a premium class. AI-92 is the optimal product that can be suitable for such a device. On average, professionals advise adding 20 to 50 ml of machine oil per liter. If the power of the unit is one and a half kilowatts, then only 25-27 ml of oil will be required.
How to dilute engine oil and gasoline, in what proportions? This question arises for all users. First you need to stock up on containers:
- A watering can, which will allow you to pour the substance into the tank
The process of mixing oil and gasoline is technologically uncomplicated. It is important to observe safety precautions so that static electricity does not accumulate, not a drop of water gets into the fuel.
Types of oils used for dilution in gasoline
What proportions should be done? The engines are mostly two-stroke, so the mixture is usually 1:50. Russian-made chainsaws function with products of the following brands:
For foreign analogues, it is permissible to use two liters of gasoline per 80 grams of oil. Foreign saws are distinguished by economical fuel consumption, the proportions of oil in them vary from 40 to 49 shares.
Shades of oil can vary significantly, this should be taken into account during operation. For example, HP produces reddish engine oil. If the composition has a greenish (sometimes blue) tint, then this is a sure sign that the product is synthetic premium. The quality of such compositions is high, the cost is also rather big.
Tips and life hacks are extremely useful in practical work, consider some of them:
- It is convenient to use canisters with dispensers, while experienced people filter gasoline through suede. The cleaner the fuel, the better the carburetor will work.
- Gasoline can actively evaporate, especially at high temperatures, a suspension falls out at the bottom of the canister, which cannot be poured into the engine.
- It is recommended to prepare fuel for no more than three operational fillings.
- The quality of the fuel can be affected by the material of the container, PVC materials react especially actively.
- If the combustible mixture is poured of poor quality, the chainsaw may be removed from the warranty.
- During operation, it is necessary to test the tightness of containers and the rhythmic operation of the engine.
- One of the first signs of a malfunction is undue heating of the circuit.
- Before subjecting the tool to severe stress, it should be tested at idle speed.
- The tank is enough when working for half an hour.
- There is still grease (residues) in the second container when it has run out in the tank.
- If a large amount of smoke is generated during operation, this means that the fuel is of poor quality.
- During the operation of the unit, do not approach an open fire.
- (distance up to 2 meters).
- Fuel should not be poured “under the rim”, leave a little space.
