Gasoline to lawn mower oil ratio

Gas found in Oil Lawn tractor Edition

What gasoline to use?

It is better to use AI-92 gasoline for modern chainsaws. It is better not to use the 95th. Firstly, because the saws are set up to work with 92 gasoline. And, secondly, 95th gasoline is obtained by adding special additives to gasoline with a lower octane number. And as experts say, this is not good.

In general, fill in 92nd gasoline and you will be happy. Just do not stock up on it, as its octane number drops during long-term storage.

In general, they say (they say!) That our refineries can produce only 80 gasoline in pure form. But already it is brought to the 92nd and 95th due to additives. In the 95th, there are naturally more additives. So, during long-term storage, these additives “evaporate” and gasoline again becomes 80th. True or not, I don’t know, but I learned this information back in 2009 at one of the seminars on servicing gasoline equipment from the head of the service department for Russia of one of the manufacturers of gasoline equipment. If this was true, then maybe today (2018) the situation has improved.

In any case, it is better to buy gasoline at proven gas stations, where you have already refueled and everything was fine.

The proportion of gasoline and oil for a two-stroke engine is 1 to 50: this is how much oil, the rules for preparing the mixture

There are certain parameters for mixing gasoline with an oil composition. It is the main fuel for two-stroke engines. The resulting fuel provides the engine for a long time, and thus maintains its productivity. How to mix the necessary ingredients in a 1 to 50 ratio, this is how much oil, will be discussed later.

Cooking recommendations

Most drivers know that a two-stroke engine runs on petrol-oil fuel. Therefore, it is recommended to observe the proportions indicated in the product data sheet.

Of course, some experienced vehicle owners create the proportion “by eye”. However, each time such a mass will have a different ratio. This will adversely affect the performance of the motor. Therefore, you need to read the instructions on the packaging.

Recommended requirements for the operation of the mixture:

  • Do not reduce the amount of oil component when mixed with fuel. You need to adhere to a ratio of 1 to 50. How much oil is this? You need to know the exact amount before pouring the mixture into the crankcase. Oil is not a cheap component, so they often try to save money on it. But this can contribute to strong heating of the system. Therefore, the proportions of the oil must be observed. Also, due to the insufficient amount of this component, scuffing may appear, which significantly reduces the duration of the motor’s operation.
  • Also, do not use copious amounts of oil. Exceeding its volume is a negative factor for engine operation. This leads to rapid wear of the motor, to an increase in carbon deposits.
  • It is not recommended to store the prepared fuel mixture for more than 30 days. Otherwise, it loses the desired properties, and its use will significantly reduce the service life of the engine.
  • It is required to ensure that there is no dust, dirt in the composition, as this will also negatively affect the operation of the motor.

What you need to know?

Choosing the right fuel mass ratio is not an easy task. It is necessary to calculate the mixing proportions in accordance with the established rate. Sometimes drivers add ingredients as they see fit. At the same time, disciplined vehicle owners who worry about the engine know that the recommended ratio is 1 in 50. How much oil is that? You will find the answer to this question below.

To mix ingredients, you need to follow simple rules. To dilute gasoline with 1 to 50 oil, it is recommended to use A-92 fuel. A-80 is often used, explaining this effect by the presence of a large number of additives in its composition. This is fundamentally wrong.

Almost any type of oil is suitable for mixing with fuel. The main thing is that it belongs to the auto group, and not intended for tractors or motor boats. This oil should not be used. Otherwise, it will clearly shorten the life of the engine.

Serving the two-stroke grass trimmer

For a two-stroke engine, the main maintenance operation is air filter maintenance. The frequency is 10 hours of operation. During cleaning, the material is washed in warm soapy water. Lightly soak the surface with oil before installing it back.

Check the cleanliness of the fuel filter (if fitted) at the same time. However, it is best to clean the fuel mixture when refueling the grass trimmer. The spark plug is checked regularly for carbon deposits. The gap between the electrodes should be 0.5 mm.

With regular care and proper use, the grass trimmer will last for years.

Mixing ratio

Often the standard mixing ratios are indicated on the oil container. And basically a ratio of 1 to 50 is used. This is how much oil should be added, we will consider below. Slight deviation from the ratio shown is possible. But it’s better to stick to exact dosages.

So, manufacturers recommend sticking to a ratio of 1 to 50. How much oil should be diluted with gasoline? The ratio of the presented proportion is quite simple:

  • 1 liter of gasoline and 20 ml of oil;
  • 1.5 liters of fuel and 30 ml of oil;
  • 2 liters of fuel and 40 ml of oil.

For the calculation, the formula is applied: 1 l / 50 1000 = 20 ml.

Therefore, 20 ml of oil is needed per liter of gasoline.

Gasoline and oil for chainsaws. which is better

Often beginners ask, which one is better to take gasoline for their instrument? In order not to make a mistake in the choice, it is recommended to read the instructions for the tool. In the instructions, each manufacturer indicates the corresponding brand of fuel. If the manufacturer indicates that the octane number should not be lower than 95, then it is not recommended to pour 92 gasoline.

It’s important to know! It must be distinguished that manufacturers produce two types of lubricants for chainsaws. for chains and engines. Chain materials are poured into a separate tool tank, and they will be used to lubricate the chain while working with a chainsaw.

Motor oils for two-stroke engines are produced by the following manufacturers:

  • STIHL
  • Kreissman
  • Sadko
  • Husqvarna

Usually, the ratio is indicated on the lubricant bottle, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Do not under any pretext use the working off even as a chain lubricant. This will lead to the fact that soon it will be necessary to repair the tool.

Consequences of violation of the ratio

The service life of the motor scooter engine depends on how accurately you follow the manufacturer’s recommended oil-gasoline ratio. The fact is that the fuel mixture enters the cylinders in the form of gasoline-oil mist. And the task of the oil composition is to lubricate the moving and rubbing parts and surfaces of various parts in the cylinder. If it suddenly turns out that there is not enough oil, and somewhere it will not be enough at all, the parts that touch dry will begin to damage each other. As a result, scuffs, scratches and chips are formed, which will certainly lead to complete or partial engine failure (for example, it can jam).

In the opposite case, when too much oil enters the engine, it does not have time to completely burn out, settling on the cylinder walls and turning over time into solid particles. coke, slag and the like. As you might guess, this also leads to engine failure. The most important thing is that you must not allow even a single violation of the proportion in the direction of a lack of oil. It is better to pour a little oil 10 times than not to add just 1 time. It often happens that this time is quite enough to break the engine.

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in case of failure of the brushcutter, you can present your claims to him, and not to a third-party source. If there is no instruction in the passport, and even more so if there is no passport, then we recommend that you look for another model of grass trimmer from a more reliable seller.

For all other cases, when you have a lawn mower model in your hands and there is no way to find out its technical features, there are standard proportions of the most likely fuel mixture components for a two-stroke engine. Basically, these units use AI-92 gasoline and a special synthetic oil, which contains a solvent for better mixing with fuel. Such oil evaporates slowly and has the ability to completely burn out in the cylinder, leaving no carbon deposits.

The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline requires 100 ml of oil, and in accordance with this oil consumption per 1 liter of gasoline is 20 ml. Knowing the amount of oil required to dilute 1 liter of fuel, you can easily calculate any rate when preparing fuel for your grass trimmer. When using mineral oils, the ratio of 1: 40 is most often the standard. Therefore, 1 liter of fuel will require 25 ml of such oil, and for a 5-liter canister. 125 ml.

When operating a lawn mower, a person with little experience in operating such equipment will not be difficult to determine and correct the actual amount of oil required for a particular model. You should only pay attention to the exhaust gases (their color, odor toxicity), cycle stability, engine heating and developed power. details about the consequences of incorrect mixing proportions of gasoline and oil can be expected in another section of the article. There are options for brushcutters running on AI-95 gasoline. This should also be considered.

If the manufacturer recommends fuel with such an octane number, then the requirements must be followed so as not to reduce the operating resource of the equipment thereby.

Gasoline to Oil Ratio for Lawn Mower

lawn mowers are a fairly common technique for combating weeds in summer cottages, in household, road and housing and communal services. These devices have two more names. grass trimmer and lawn mower. These units differ in their engines. The more expensive ones have four-stroke engines, all the others have two-stroke engines. Of course, the latter are the most popular among the population, since they are simpler in design, lighter in weight, and much cheaper than their four-stroke competitors. However, two-stroke models are inconvenient in that the fuel mixture for them must be prepared by hand, maintaining a strict dosage between gasoline and oil. In four-stroke analogs, the mixing of these components occurs automatically, you only need to fill the gas tank and oil tank with the corresponding substances. Let’s consider the question of the correct refueling of two-stroke brushcutters, since it depends on how effective and long the operation of such a unit will be.

Mixing rules

And now about how to mix the components correctly. However, it would be more logical to start with an analysis of common, but absolutely unacceptable mistakes that many owners of this mowing unit “sin” with. The following actions are considered as mixing errors.

  • Adding oil to the fuel already poured into the brushcutter’s gas tank. In this way, a homogeneous fuel mixture cannot be obtained. Perhaps you will succeed if you only shake the grass trimmer for a long time. But it is unlikely that someone will do this, given the severity of the unit.
  • First pour oil into a mixing container, and then add gasoline to it. Gasoline has a lower density than oil, so if it is poured into the oil, it will remain in the upper layer, that is, natural mixing will not occur. Of course, it will be possible to mix later, but it will take much more energy than if it were done the other way around. pour oil into the poured gasoline.
  • Ignoring precise measuring instruments for taking the required quantities of ingredients used. In other words, diluting the amount of oil or gasoline “by eye” is a bad habit when operating motor vehicles.
  • Take empty drinking water bottles for preparation of the fuel mixture. Such a container is made of too thin polyethylene, which can dissolve with gasoline.

Considering all of the above, we recommend using the following rules when mixing the fuel mixture for two-stroke engines of the grass trimmer.

  • Use only clean containers made of metal or special plastic for storage of gasoline, oil, ready-made fuel mixture and its preparation.
  • Use a watering can to pour gasoline into a dilution container to avoid spilling, and to add oil. a measuring container with volume risks or a medical syringe for 5 and 10 ml.
  • First, pour gasoline into the canister for preparing the fuel mixture, and then oil.
  • To dilute the mixture, first pour only half of the planned volume of gasoline into the container.
  • Next, add to the gasoline the entire amount of oil required to prepare the mixture.
  • Mix the contents of the dilution container thoroughly. It is best to stir by making circular movements with a tightly closed container. Do not stir the fuel inside the canister with any foreign object, since it is not known what material this object is made of, what reaction it can enter into with the ingredients of the mixture, how clean it is.
  • Add the rest of the gasoline to the mixed mixture and mix thoroughly again.
  • You can fill the mower‘s fuel tank with the prepared mixture.

It must be borne in mind that the ready-made fuel mixture should not be stored for more than 14 days, as it loses its properties, stratifies and evaporates, which leads to changes in proportions, and therefore a deterioration in the operation of the grass trimmer.

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.

You can start selection even by country of origin.

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.

What gasoline to fill

Gasoline for the grass trimmer should be chosen unleaded with a stroke number of 92 or 95. As practice shows, AI-80 gasoline can lead to device breakdowns, which is a questionable economy.

Fuel must be fresh, that is, after purchase, it can be stored for no more than 60 days.

Other factors also affect the quality of the fuel, such as using a special lawnmower lubricant and diluting it in a separate container. It is also recommended to use special canisters designed for storing gasoline.

Benefits of the Gasoline Grass Trimmer

A gasoline-powered lawnmower has several advantages:

  • high power and performance;
  • the possibility of refueling at any time of operation;
  • the possibility of using a nozzle. a rotor for cutting small trees or shrubs;
  • mobility (the ability to use anywhere. on the site or in the field).

Gasoline mowers are available in 0.5 liter, 1 liter and 1.5 liter tank volumes.

Features of operation of Huter GGT-1500TX

The operation of the grass trimmer is not very difficult, and after carefully studying the instructions and assembling the resulting product, you can start preparing the grass trimmer for work. Let’s briefly consider how to properly assemble the Huter GGT-1500TX and prepare it for use. At the initial stage, we install the control handles using a special key included in the delivery set. When connecting elements, always check that everything is done securely. Now you can move on to the next step: connecting the boom to the motor. Installation is carried out using a standard set of bolts. Once the boom is connected to the motor, the shroud and cutting elements can be installed. Read more about the step-by-step assembly of the grass trimmer in the Owner’s Manual.

The assembled grass trimmer can now be prepared for the upcoming work on the site. Preparation for operation begins with the preparation of the fuel mixture. At this stage, follow all the manufacturer’s recommendations on the brands and quality of the fuel mixture components, and also accurately follow the method of preparing the fuel mixture, which, in fact, is not very difficult.

Since the Huter GGT-1500TX is equipped with an air-cooled two-stroke engine, a high quality oil, specially produced for the mentioned type of engines, is needed to prepare the fuel mixture. According to the classification, this oil is API TV / API ТС, JASO FB / JASO FC. It is recommended to fill in oil which is produced by Huter itself under the Huter 2T label. The second component of the mixture must be high quality gasoline, the octane number of which is at least 92. It is strictly forbidden to use oils in the fuel mixture that are produced for water-cooled engines. The fuel mixture is prepared in a ratio of 1:40 (1. oil, 40. gasoline) or according to the recommendations of the oil manufacturer.

For the process of preparing the mixture, use a special measuring container. The amount of the mixture should be calculated only for one cycle, so that after the completion of the work, there are no residues of the fuel mixture in the tank (you cannot leave it in the tank until the next cycle of work). Also, never use the tank itself for preparation of the mixture, and also do not carry out operations with the components of the fuel mixture near a fire and do not smoke while preparing the fuel.

After the correctly formulated fuel mixture is poured into the tank, you can proceed to the direct preparation of the grass trimmer for work. To do this, the user must first put on a knapsack belt and fasten it securely, but conveniently for himself. After that, using a special carabiner, the grass trimmer is attached to the belt and adjusted if necessary. For details on preparing the grass trimmer for use, see the Owner’s Manual.

Work conveniently and safely

Of course, the operator must follow all safety recommendations and requirements, follow the rules for using the grass trimmer. However, in addition to this, the manufacturer has taken a number of measures in relation to the design of the device in order to increase the level of safety when working with the brushcutter. These include, in particular, the presence of:

  • a protective cover to prevent bouncing stones and debris from falling onto the user,
  • throttle blocking trigger to prevent operator accidentally pulling the trigger and starting rotation
  • cutting tool when the engine is running,
  • anti-vibration system to prevent harmful effects of the vibrating elements of the grass trimmer on the hands and other parts of the operator’s body.

Fuel mixture for two-stroke engines

Grass trimmers, which are equipped with a two-stroke motor, do not have a separate system for supplying oil to lubricate the rubbing parts. For this reason, such devices should be refueled not with pure gasoline, but with a mixture of fuel and engine oil. The latter should be specially designed for two-stroke engines. Application of automotive engine fluid will lead to premature engine failure.

Preparation of a fuel mixture for two-wheel engines

You need to refuel a lawnmower with a two-stroke engine with AI-92 gasoline. When using AI-95, overheating of the engine and uneven operation of the unit can be observed. You need to mix gasoline with oil in a ratio of 50: 1, where 50 is fuel, and 1 is oil. It turns out that 1 liter of fuel will require 20 ml of oil.

If the motor is worn out or the tool is under heavy load, then the ratio is 25: 1. If there is little lubrication, then scuffs will appear on the cylinder walls and the piston surface. Then the piston ring will undergo destruction, causing the engine to jam. An overabundance is not so critical, but it can lead to the formation of carbon deposits. At the same time, the piston ring will coke, which will reduce the power of the device.
