How much oil to put in petrol for brushcutter

How much oil to put in the gasoline for the lawnmower?

At the beginning of work with the tool the question always arises, how much oil to add to gasoline for a chainsaw or grass trimmer. It is important to remember that for two-stroke engines the ratio is 1:50, t. е. 100 ml of oil per 5 liters of fuel.

What gasoline can be poured into the trimmer for grass? In order to prepare this mixture you need a specific grade of gasoline AI-95 or AI-92. Gasoline brand depends on its ignition rate. octane number. The lower the octane number, the faster the gasoline burns and the higher the consumption.

How much oil to 1 liter of gasoline?

The instructions for your chainsaw say the oil to gasoline ratio, for example, 1:50 for brand-name oils means that 1 liter of oil should be mixed with 50 liters of gasoline. You get the right proportion if you add 20 grams of oil to 1 liter of gasoline.

As a rule, the ratio of oil to gasoline in a gasoline trimmer from reputable manufacturers is 1:40 or 1:50, which means 1 part oil to, say, 40 parts gasoline. Now the arithmetic: 1 liter of petrol = 1000 ml of petrol, divide by 40 and you get 25 ml of oil.

What grass trimmers are?

There are two basic types of these devices. What gasoline is needed for the grass trimmer and how much oil to pour. These are gasoline and electric. From the name it is clear that their main difference is the power source. Each type has both advantages and disadvantages. The advantage of gasoline is the lack of a cord for power, which does not limit the owner in moving around the site during operation. But an electric one needs 220 V plugs for power. There is no way to do without an extension cord, which will always get in the way and get tangled underfoot.

Modern trimmer for grass, which runs on fuel, thanks to the presence of various interchangeable heads, has turned from an ordinary grass trimmer into a means of small-scale mechanization with many functions. By installing the appropriate attachment, the owner will not be difficult to form a crown in shrubs on a personal garden plot. What gasoline is needed for the grass trimmer in these models can not use gasoline for the. In a snowy winter it is possible to use it as a snowplow. The very replacement of the working heads trimmer for grass will not take much time and can be made with or without a tool.

Gasoline for your chain saw

As a rule, the manufacturers of Russian gasoline usually write in the annotation that gasoline must have an octane rating of over 90. As for the oil and gasoline ratio, you should also look at the annotation. For one saw 1 to 30, for others. 1 to 40, but, for example, for chain saw Husqvarna 1 to 50.

Dilute 50 ml per liter of gasoline for two-track internal combustion engines. you can’t go wrong. It is better to use AI 93 or AI 95. The exact gasoline brand and ratio are preferably written in the booklet that came with the machine

Get the manual for your chain saw, usually it’s a book, from which case you bought the lawn mower. It will certainly indicate what are the requirements for gasoline. It is usually necessary to fill it up with 1:40 ratio, but 1:30 is also possible. In other words, 1 part oil and 40 parts gasoline. The ratio is also indicated on the oil packages. We buy 92 gasoline, mix it with oil in a separate canister and then fill the lawnmower and the chainsaw with this consistency.

In most cases, two-stroke engines in gasoline mowers use gasoline AI-92, and the oil to gasoline ratio 1k40. If you don’t know, you can test 1k30. And then to see how the mower behaves and adjust in one direction or another.

A 2-stroke engine is usually used in chain saws. Accordingly, it is necessary to use a fuel mixture, on which a 2-stroke engine works. Because the engine does not have a complex lubrication program, the oil is added to the fuel. If you do not add oil to the fuel, then the engine in a short time is out of order because the rubbing parts work dry and overheated. At first the piston, piston rings and the cylinder suffer. In recent years, all domestic manufacturers recommend using gasoline with an octane number not lower than 92 with oil for 2-stroke engines in the ratio of 40:1. If the engine is new or repaired, there is an option to add some oil not just temporarily running-in (25:1). Always check the label on the oil can if you don’t know the manufacturer’s advice. If it is a question of changing the proportion, it is better to give oils than just. With all that, the risk of engine failure will be the least.

Oil requirements

The mixture of gasoline and oil chosen for your brushcutter must meet the necessary requirements specified in the manual. It is important to note that domestic manufacturers often label their products slightly differently from the American or Japanese classification. Russian producers of lubricating products, as a rule, put marking 2T on all oils, intended for two-stroke engines. It is not uncommon to find oil cans on store shelves with o or “pre mix” on them. In the first case this means that the oil does not need any additional manipulation, you just pour petrol and oil into the same container and the mixing is done without human intervention. In the second case, respectively, you will have to shake or shake the mixture to bring it to the desired consistency.

As you can see, the existence of different classifications of lubricants suggests that the use of oils in two-stroke engines is necessary. This is due to the fact that the fuel mixture without lubricant fairly quickly put out of operation ICE, which will not be lubricated properly. Gasoline and oil form a necessary medium which reduces detonation, removes superfluous waste (waste products from gasoline combustion) and protects the engine interior from wear.

It is important to remember that using the wrong oil classification can cause the motor to break down or clog. Of course, it can be repaired, but in order to prevent possible damage, and to minimize its probability, it would be better to study the instruction manual, find out the volume of the two-stroke engine installed on the brushcutter, and use only gasoline and oil that will suit this model by all parameters.

Quite often in the recommendations section (and sometimes on the label) the manufacturer indicates the partner companies, which gasoline and oil it recommends to fill in their models. Most often the fuel and lubricant recommended by the manufacturer will suit the grass trimmer best.

First of all, you should immediately exclude all oils of unknown (garage, basement) origin from the list of actively used lubricants. Usually it is not easy to dilute such oils because of the unclear basis, composition. As a rule, the labels of non-brand producers are not replete with information, covering only general information, without specifying. It is strongly not recommended to dilute and dilute oils like AC-10 and ACZp-10. The origin of these lubricants is usually quite vague, it is better to give preference to proven brands, which are used every day by thousands of people across the country.

The distinctive feature of all oils for two-stroke engines is the fact that the manufacturers paint them in a color contrasting with that of gasoline. The liquid is translucent, viscous in consistency, slightly yellowish, but not thick. Usually we are talking about three colors. red, green and blue.

Do not forget that the color range does not affect the classification in any way (as is often the case with antifreeze).

Under no circumstances should you use oils from a line not designed for the grass trimmer. This can be extremely detrimental to the operation of the power unit, leading to increased fuel consumption, fouling of spark plugs and a whole range of other problems that will have to be identified and eliminated. It should be noted that if the fact of using oil that is not included in the tolerance is established, the seller has every right to remove the machine from the warranty. This means that the replacement of defective parts will have to be at your own expense, and no exceptions will not help.

If the purchased fluid does not have the declared qualities (for example, too liquid), in no case you should not mix it with gasoline. It will be best to return such oil back to the store, explaining to the seller the reason for the return.

How to Get the Proportion Right?

The lawnmower is filled with A-92 gasoline. There are other factory annotations that require gasoline of the second octane number. For example, A-95. The price difference is small.

Oil selection does not take liberties. For two-stroke engines, the API sets a certain order:

• For power tillers, brush cutters, air-cooled mopeds. And class;
• Engines with 200 cm³ cylinder displacement. TV oil;
• For cross-country vehicles and bikes it is advised to use class TC oils;
• Yacht engines, jet skis, powerboats use TD-brand lube.

From the above list of lubricating oil of the last 2 positions are not recommended for power units trimmers. Alphabetic designations indicate what petroleum products the lubricant is made of.

Oil Requirements

The mix of gasoline and oil you choose for your brushcutter must meet the necessary requirements specified in the manual. It’s important to note that Russian producers often mark their products in a different way from the American or Japanese classification. Russian lubricant producers, as a rule, put the 2T marking on all oils designed for two-stroke engines. It is not uncommon to find oil cans marked “self mix” or “pre mix” on store shelves. In the first case, it means that the oil does not require any additional manipulation, just pour petrol and oil into one container, and mixing will occur without human intervention. In the second case, respectively, the mixture must be shaken or agitated to bring it to the desired consistency.

As you can see, the existence of different classifications of lubricants suggests that the use of oils in two-stroke engines is necessary. The reason is that a fuel mixture without lubricant quickly puts the engine out of operation, which will not be lubricated properly. Gasoline and oil form the necessary environment that reduces detonation, removes excess debris (waste products from the combustion of gasoline products) and protects the inside of the engine from wear.

It is important to remember that using oil of the wrong classification can cause engine damage or clogging. Certainly, it will be possible to repair it, but to prevent possible breakages, and to reduce their probability to a minimum, it will be better to study the instruction manual, to know the volume of the two-stroke engine installed on the brushcutter, and to use only petrol and oil, which will suit this model according to all parameters.

Quite often in the recommendations section (and sometimes on the label), the manufacturer indicates the partner companies, whose gasoline and oil he recommends to fill their models. often than not, the fuel and lubricant recommended by the manufacturer will suit the grass trimmer best.

First of all, you should immediately exclude all oils of unknown (garage, basement) origin from the list of actively used lubricants. Usually it is not easy to dilute such oils because of the unclear basis, composition. Generally, labels of unbranded manufacturers are not very informative, giving only general information without specifying. It is strongly not recommended to dilute and dilute such oils as AC-10 and ACZp-10. The origin of these lubricants is usually quite obscure, it is better to give preference to proven brands that thousands of people across the country use every day.

Fuel mixture for two stroke engines

Grass trimmers, which are equipped with a two-stroke motor, do not have a separate system designed for oil supply in order to lubricate the rubbing parts. That is why you should not fill such devices with pure gasoline but with a mixture of fuel and engine oil. The latter must be specially formulated for two-stroke engines. The use of automotive engine fluid will lead to premature engine failure.

Preparation of fuel mixture for two-roller engines

To fill a lawn mower with a two-stroke engine needs gasoline AI-92. If you use AI-95, the engine may overheat and the engine may be unevenly running. Gasoline and oil should be mixed in the proportion 50:1, where 50 is fuel and 1 is oil. It looks like you need 20 ml of oil for 1 liter of fuel.

If the engine is worn or the tool operates with a high load, the ratio is 25:1. If there is not enough lubricant, you will get scuff marks on the cylinder walls and piston surface. The piston ring will then be destroyed, causing the engine to seize. Too much is not so critical, but it can lead to carbon deposits. Piston ring will get corked, which will reduce the power of the device.

Types of brushcutters

Today on liquid profile trading platforms there is a great choice of mechanisms for cutting grass, small bushes. For example, there are lawn mowers with electric motor, with gasoline-powered engines. No brushcutters equipped with diesel engines, because they are low-revving.

Liquid statistics show the advantage of lawn mowers with internal combustion engines over their electric counterparts. Electric lawnmowers are used in places where there is a fixed electrical grid.

How to dilute petrol and oil for grass trimmer

Only use the correct ratio of petrol for your grass trimmer. Not enough oil can cause poor lubrication of the lawnmower, which leads to fast wear and tear.

Find out the correct ratio in the trimmer manual. Most often it is equal to 1:25, 1:40, 1:50. 40 ml, 25 ml and 20 ml of oil must be added to 1 liter of gasoline, respectively.

It is not allowed to mix petrol and lubricant directly in the fuel tank. The proportion of oil and petrol should be strictly observed. If this rule is ignored, the operation of the grass trimmer engine may be unstable, causing it to fail quickly.

It is not recommended to use plastic bottles or canisters for this purpose. This is due to the fact that gasoline tends to dissolve plastic, which means that some of the plastic can get into the fuel tank, which can lead to carburetor failure. Although there are special plastic canisters marked “flame”.

• gasoline;
• Oil suitable for two-stroke engines with an air cooling system;
• A canister, preferably a metal canister;
• a container for mixing, also better a metal one;
• gloves;
• respirator.

Make a mixture of gasoline and oil as follows:

• Pour 1 liter of gasoline into a container, add half of the oil. Stir thoroughly, being careful to avoid open flames.
• Add the rest of the oil to the gasoline of the weed trimmer and mix thoroughly again. Now the fuel can be poured into the fuel tank of the grass trimmer.

The mixture can be stored for up to three months, so it is better to dilute the gasoline in such an amount that it is enough for several uses.

Only quality oil may be used for dilution, and it is recommended to buy it only from trusted stores, such as specialized hypermarkets.

Standard proportions

According to the standard, to prepare gasoline-oil mixture, you have to take technical liquids in the ratio of 1 to 50. This means that it is necessary to add 200 milliliters of oil to 10 liters of petrol. If you need to dilute the amount per 1 liter of gasoline, then use the formula according to the rule of proportion.

Please note that if you use mineral oil, the ratio is lower, usually about 1:40 per liter of gasoline.

Why does the lawn trimmer not start well??

There can be many reasons why the grass trimmer does not start.

The most common causes of difficulty starting are:

• fuel quality problems;
• faulty spark plugs;
• Contamination of air and fuel filters;
• problems with pressure equalization in the gas tank;
• faulty exhaust port.

Most of these faults are not critical and you can fix them yourself. Let’s see in detail how to do it.

Fuel

Do not skimp on fuel for your equipment, use only quality gasoline and oil. Strictly adhere to the recommended proportions for the fuel mixture. It is also not a good idea to leave fuel in the tank for a long time. it will eventually become watery and lose its properties.

The spark plugs and the spark plug duct

If you suspect spark plug failure, immediately unscrew the old spark plug and replace it with a new one. If you cannot replace the spark plug right away, clean and dry the old one thoroughly. Drain off the excess fuel through the spark plug passage and dry it thoroughly. After that screw it back in, set the gap to 1mm and try to start the engine again.

If the offered manipulations didn’t give the desirable result. check the spark plug contact. Also the cause of lack of spark may be a faulty ignition unit, which you are unlikely to be able to repair yourself.

Air and fuel filter

If these lawnmower parts get dirty, you either have to replace them completely or clean them thoroughly. When replacing the fuel filter do not leave the intake tube without protection. it can cause damage in the engine piston system.

Problems with pressure equalization in the fuel tank

This malfunction is caused by a contaminated breather plug. If it gets blocked, it creates a vacuum in the tank, preventing fuel flow. You can clean the breather plug with an ordinary needle.

If after checking these systems trimmer for grass has not started, most likely the reason for the problems with the carburetor (clogged jokers, breached tightness) or engine (piston ring wear, chips on the cylinder). Repair of this type can also be made independently, but it is better to trust the professionals of the service center.

Today, there are few people left who use an ordinary scythe on their garden plot. This “ancient” method is practically never met. And many already have no idea how to handle it, sharpen and rivet. With the development of technology there are devices called grass trimmers.

There are two basic types of such devices. This petrol and electric. From the name it is clear that their main difference is the power source. Each type has both advantages and disadvantages. The advantage of gasoline-powered is the absence of a cord for power, which does not limit the owner in moving around the site during work. The electric one, on the other hand, needs 220 V mains for power. There’s no way to do without the extension cord, which will always be in the way and get tangled underfoot.

Modern trimmer for grass, which runs on fuel, thanks to the presence of different interchangeable heads, has turned from an ordinary grass trimmer into a means of small-scale mechanization with many functions. Installing the appropriate nozzle, the owner will not be difficult to form a crown of shrubs on a personal garden plot. In the snowy winter, it can be used as a snowplow. Replacement of grass trimmer working heads does not take much time and can be done with or without a tool.

What is the right oil for your grass trimmer??

When using such a device as a gasoline trimmer for grass, the special complexity causes its maintenance. When the time comes to change the oil, many people do not know what oil to pour into the trimmer for grass.

In each case, everything depends on the type of grass trimmer engine. In its majority, it is similar, but of higher power, used in the manufacture of mopeds. It is therefore necessary to use trimmer oils that are labeled 2T.

In most devices of this kind, oil is filled with gasoline. Therefore, the owner must be sure to know, using a grass trimmer, the ratio of gasoline to oil. In most cases, 20 grams of oil per liter of fuel. The higher the fuel quality, the lower the oil consumption.

There are also 4-stroke engine models for trimmers. In these trimmer oils are poured into a separate container, which does not cause much difficulty. One of the main advantages of these devices is their low noise level, which allows you to work without headphones. Trimmer oils are marked 4T, which must be paid attention to.

Advantages and disadvantages of gasoline trimmers

Thus, summarizing the above, it is necessary to note the main advantages and disadvantages of gasoline trimmers. The pluses can include:

• more weight;
• the amount of noise emitted during operation is greater than that of electric trimmers. Despite this, the number of gasoline trimmers in suburban areas is only increasing.

Fuel

It remains to choose which gasoline to fill in the trimmer for grass. The choice is not great. AI-92 and AI-95. The difference between them is quite significant. If the manufacturer’s instructions do not specify what gasoline to use, it is necessary to stop at AI-92. It almost does not depend on the brand of gasoline, how much oil to add per liter of gasoline, if the fuel is of high quality and fully complies with the declared brand. Buy gasoline only at a gas station, where the risk of buying A-80 instead of AI-92 is practically nil.

If it is recommended to fill in AI-95, then do not use other brands of gasoline. If the engine starts, it will run irregularly and quickly overheat. So you run the risk of damaging the engine not only the domestic grass trimmer, but also the professional one.

Consequences of a faulty ratio

The correct oil to petrol mixture ratio depends on how well you adhere to the manufacturer’s recommendations. 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 friction parts and surfaces of a variety of parts that are in the cylinder. If suddenly it turns out that there isn’t enough oil, and somewhere there isn’t enough oil at all, the touching parts will start to damage each other. As a result, scoring, scratches and chips are formed, which will certainly lead to complete or partial engine failure (e.g., it can jam).

In the opposite case, when too much oil gets into an engine, it has no time to be completely burnt out, depositing on the cylinder walls and turning into solid particles with time. coke, slag and the like. As you might guess, this also leads to engine failure. The most important thing that should not be allowed. even a single violation of the proportion in the direction of the lack of oil. It’s better to overfill a little oil 10 times than underfill just once. It often happens that just once is enough to break the engine.

How to mix

If you do not have a special measuring jug with graduations, which are included with each noteworthy trimmer for grass, or such a container is lost, then use any suitable container. Better a glass one or a metal one. Plastic can also be used, but you must choose a bottle with rigid walls.

The vessel must be a multiple of 1 liter. You can take a bottle and 1.5 liters, but practice shows that it is not very convenient. You also need a medical syringe, preferably for 20. 50 milliliters. First pour petrol into the container, then add a precisely measured amount of oil (by volume). You can’t change the sequence of operations.

If you have a “pre-mix” oil, then close the bottle or canister with the cap and turn it upside down several times and shake it vigorously. If you have a “self-mix” oil, it will dissolve on its own. Prepared mixture must be used within one day. If you know how much fuel a grass trimmer consumes for a certain amount of work (or time), it is not difficult to calculate the amount of mixture. Otherwise, dilute new fuel before each refueling so you have a minimum amount left over.

Rules of mixing

And now about how to mix the components correctly. However, it would be more logical to begin with analysis of widespread, but absolutely unacceptable mistakes, which “sin” many owners of this mowing unit. The following mistakes are considered mistakes when mixing the fuel mixture.

• Adding oil to the fuel already in the brushcutter‘s gas tank. This is not a way to obtain a homogeneous fuel mixture. It may work, if only then shake the grass trimmer for a long time. But this is unlikely to be done, because of the machine’s weight.
• Pour oil into the mixing tank first and then add gasoline to it. Gasoline has a lower density than oil, so if you pour it into the oil, it will remain in the upper layer, that is, the natural mixing will not happen. Of course, you can mix it afterwards, but it will take much more energy than if you do it the other way around. pouring oil to the poured petrol.
• Disregarding accurate measuring tools for taking the necessary volumes of ingredients to use. It is a bad habit to dilute the amount of oil or gasoline “by eye” when operating a motorcycle.
• Using empty drinking water bottles for the fuel mixture. Such containers are made of too thin polyethylene that can be dissolved by gasoline.

Taking all the above mentioned into account, we recommend to use the following rules when mixing fuel mixture for two-stroke engines of grass trimmer.

• Do not use containers made of metal or special plastic for storing or preparing gasoline, oil, fuel mixture.
• Use a watering can for filling petrol to avoid spilling it, and for adding oil use a measuring cup with volume indicators or a 5 ml and 10 ml medical syringe.
• Pour gasoline first into the canister to prepare the fuel mixture, and then the oil.
• to dilute the mixture, pour only half of the planned amount of gasoline into the tank first.
• Next add to the petrol all the amount of oil required for the mixture.
• Thoroughly stir the contents of the dilution tank. It is best to stir with a tightly closed container in a circular motion. Do not use any other object to stir the fuel inside the canister, because it is not known what material it is made of, what reaction it may have with the ingredients of the mixture and how clean it is.
• add the rest of the gasoline to the stirred mixture and stir it again thoroughly.
• You can fill the lawnmower’s fuel tank with the mixture you have prepared.

It should be borne in mind that the ready 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, deteriorates the work of the trimmer for grass.
