Do I Need To Pour Oil Into A Trimmer

So, have you finally become the owner of a petrol lawn mower or lawn mower? And your imagination already creates images of how you courageously deal with dense grass. However, the dream of an “ideal lawn” remains a dream when the question involuntarily arises: which oil to use and what are the proportions of mixing it with gasoline?

You can find a lot of information on the correct preparation of the fuel mixture on the Internet. This topic is actively discussed in forums and other thematic resources. But, despite such an active discussion, there are many inconsistencies that we have to deal with.

Actually, it doesn’t matter what technique is used, it can be a lawn mower, lawn mowing or chain saw, they are united by one. two-stroke gasoline engine. Unlike 4T, it does not have an oil sump. For its nutrition, the preparation of a special fuel mixture consisting of gasoline and oil is required. The resulting liquid is fed directly to the engine (carburetor). During use, all actively working parts are carefully lubricated, contributing to trouble-free operation under any operating conditions.

Lawnmower Engine Oil

Depending on the chemical composition, lubricants are divided into the following main groups:

Mineral They are made on the basis of oils obtained from petroleum distillates. They are highly viscous and require frequent replacement. The material is intended for low power equipment with an air cooling system. It is recommended to use in warm weather.

Semi-synthetic. They represent a kind of “golden mean”. They are based on a mixture of mineral and synthetic oils. Such grease can be used in 2T and 4T engines, landscape gardening and other equipment with air and liquid cooling.

Synthetic. They are made on the basis of special synthetic components containing esters. Differ in low viscosity and long term of operation. They can be used year-round, regardless of temperature conditions. Ideal for complex machinery designed to work in harsh conditions with constant variable performance.

Any two-stroke oil, thanks to its 20% solvent composition, mixes well with fuel and has the characteristic of complete combustion. The second characteristic feature of them is the color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, and some worse. This is done solely so that it is convenient for the user to distinguish oil from pure gasoline.

Motor oil classification:

The required oil parameters for 2T engines are specified in the requirements of API TC JASO FC, API TC JASO FC ISO GD and API TC JASO FC E-GC. The most widely used classification system API. Based on this, 2T engine oils are divided into 4 large groups:

TA. Suitable for household appliances with an air cooling system and an engine displacement of not more than 50 cm3.

TB. It is used for more powerful equipment with an air cooling system and an engine capacity of 50. 200 cm3.

TC. It is used in technology with high demands on the quality of oil. It is a high-performance lubricant for two-stroke engines with a volume of 50. 200 cm3. Great for lawn mowers, lawn mowers, trimmers, chain saws and other garden equipment.

TD. for outboard motors with liquid cooling.

The most suitable material for 2T motors of API-TB and API-TC class. However, you must refer directly to the product passport, where the manufacturer indicates the brand of motor oil recommended for its equipment.

Important! For lawn mowers, lawn mowers and other 2T garden devices, a special engine oil is provided for two-stroke engines with an air cooling system and marked “for garden equipment”. It is forbidden to use lubricant for 2T engines with a liquid cooling system. Oil for boat outboard engines, motorcycles and other equipment is also not recommended.

The ratio of oil to gasoline for lawn mowers: why is accuracy so important?

We all loved to “chew” in childhood, so the process of preparing the fuel mixture is not only simple, but also interesting. First of all, it is worth considering the fact that the proportions of the mixture can be different. It depends on the engine configuration, oil labeling and manufacturer’s recommendations. The fact is that with insufficient lubrication, heating of the cylinder and piston occurs, which leads to shallow tearing of all rubbing surfaces and, consequently, to failure of the cylinder. piston group. Well, in the case of its excess, on the contrary, we get coking of the piston ring and the formation of a large amount of soot.

And even despite the fact that there is a generally accepted mixture ratio of 2% (for each liter of gasoline 20 ml of lubricant). The proportions in the mixture are still recommended to withstand accurately.

How much oil to pour in gasoline for lawn mowers?

Everything is quite simple, subject to the correct balance, the engine runs in full, all parts are carefully lubricated and not abraded. As a result, we get confidently working equipment that will last more than one season.

To know how much oil to add to the lawn mower, you need to familiarize yourself with the operational characteristics of the product. Proportional ratios can be represented in this form: 1:25, 1:40 and 1:50, which means 1 part of oil for 25, 40 or 50 parts of gasoline.

1 liter of gasoline = 1000 ml

To determine the required amount of oil for a ratio of 1:25, you need 1000/25 and we get a proportion of 40 ml.

We perform the same actions to a ratio of 1:40 and 1:50:

1:40 (per 1 liter of gasoline 25 ml of oil)
1:50 (per 1 liter of gasoline 20 ml of oil)

To ensure that the proportion of oil for lawn mowing is correctly observed, it is recommended to use a special measuring container (not plastic). Exclude a possibility of hit in a fuel mix of dirt and water. this may affect its quality. It’s better to start cooking the mixture with gasoline. Pour it to the desired mark, then add oil. A pair of tank slopes are sufficient for mixing. The liquid quickly connects and takes on a uniform shade, which, depending on the structure of the oil, may be red, green, blue or another. Then the correctly prepared mixture is poured into the fuel tank of the equipment.

Before using the equipment, make sure that the tank cap is tightly closed. If you have more fuel, then the remainder can be stored in a special canister or container for mixing (no more than 14 days). It is recommended to drain fuel that is not used up to the end.

Important! Be sure to follow safety instructions. Mix liquids in an open area so that caustic gasoline fumes do not accumulate in the room. Wear gloves and long sleeve clothing. Do not smoke or set fire to anything.

Petrol

AI-92 octane gasoline is considered the most popular type of fuel for two-stroke engines. Due to the relatively low cost, it is extremely rarely falsified. Therefore, not one hundred percent, but in its quality you can be sure. It is also permissible to use a fuel grade AI-95.

As for the storage of fuel, its period should not exceed 3 months. Over time, gasoline loses its properties, the resin content becomes higher and a polymerization process occurs, which adversely affects the combustion chamber. The fuel mixture for lawn mowing made from low-quality materials, settles in the form of soot, as a result of which the main components and systems of the engine suffer.

Recommendations for use and storage

The fuel is ready, filled in the fuel tank, the first spurt and the long-awaited start. However, if you want the equipment to work as long as possible, it is recommended that you first run it in. In order to avoid overheating of the engine, it is recommended to adhere to an average load. After the main elements of the system are carefully lubricated, the load can be increased.

Certain rules should also be followed when preparing the braid for off-season storage:

Drain remaining fuel from the fuel tank and run the final run until the fuel is completely depleted. Then, suspend operation and make sure that the engine is completely cool.

Carefully turn out the spark plug and fill in with about 5 ml of lubricant. Pull the starter handle slowly so that the oil is evenly distributed inside the engine. After that, return the candle to its original state. Store the equipment in a cool, dry place.

Summary

In recent years, a new theme has been added to the piggy bank of automobile holders. whether it is necessary to fill oil in the filter when replacing oil in the engine. It would seem that for a question, our fathers and children on the Zhiguli and Muscovites have been pouring for decades and we have been taught this, but in recent years this practical ritual has been called into question. The reason is in the official instructions for servicing modern car models. If you look there, you will not find requirements in one when filling the oil to the brim to fill the filter. Lubricate the gum before installation. yes, fill the entire volume of the filter. no. This is where the theme for the holivar is built. on the one hand experience, on the other hand modern instructions, which, however, are far from always aimed at increasing the resource or the convenience of the car owner.

We listen to the arguments of the supporters of both versions, just like in some kind of rap battle.

It is necessary to fill in!

Those who flood and recommend to others usually give two reasons to do so.

Firstly, it is believed that if the filter element is dry, then it can break during a sharp supply of oil, and if it is soaked beforehand, the risk of this will be significantly reduced.
Secondly, if you do not fill it, the oil will go longer to the engine at the first start-up, because you first need to fill the filter capacity, but it is not so small. It turns out that the motor will work for some time (albeit relatively small) without lubrication, and this is harmful.

By modern standards, the arguments, I must admit, are so-so. Earlier filters may have been torn by the wind, but now if you do not buy a frank marriage, it is difficult to imagine something like that.

In addition, from the point of view of physics, the version at “soaking” sounds a little strange. You can’t argue about the flow of oil into the engine, but here it is. Oil pumps on modern cars are very productive, they pump a huge amount of liquid and filling the filter for them is a matter of a second, while the engine does not start dry. As you do not drain the old oil, anyway, the film remains on the walls. It is she who will save the rubbing parts of the engine for that second until fresh liquid ripens.

Probably, in those days when the filters were made of something incomprehensible, and the performance of the oil pumps was like that of a water pistol, these arguments were significant, but today they do not carry anything wrong.

No need to fill!

Supporters of an oil change without filling the filter cite their scary arguments.

Firstly, when pouring oil into the filter, you can inadvertently bring air or dirt into it, which then goes into the motor, and this is fraught with problems.

Secondly, this filling the oil into the filter is simply inconvenient, the extra operation increases the time and laboriousness of the work, and it’s a little more convenient to spin the dry filter than filling it with oil.

Arguments, of course, are also like themselves. You can bring in garbage, if you wish, but you just have to try it hard. work in a very dirty place or be megabags. Well, in addition, the filter, as it were, exists in order to protect the motor from dirt in oil. If you do not drop something openly piercing and cutting into him, then he must stop any “byaku”. Words about the laboriousness of pouring oil into the filter also cause a smile, if it is difficult, then maybe you should not change the oil yourself?

The only reasonable argument is the twist issue. Indeed, for some motors, the filter is installed at such an angle that when installing a “full” filter, some of the oil can be spilled. This is unpleasant, but not fatal either.

Commentary by the “judges”

It seems to us that the debate about pouring oil is sucked from the finger. If earlier there were technical reasons to screw the filled filter, then for modern technologies they are no longer relevant. However, to say that following traditions will lead to some problems is also strange. With the exception of old cars and models with a distorted arrangement of the oil filter, there is no difference, and what to think about whether to fill the oil with a filter or not, it is better to carefully monitor the replacement interval and the choice of oil itself. But with this, if you do not inspect, real, not far-fetched problems may arise.
