Proportion Of Oil Gasoline For 2 Chainsaws

Oil dosage in Chinese version

Many chainsaws of the Chinese assembly are simplified copies of popular models of European design. The absence of special materials and proprietary technologies contributes to the preservation of the outdated proportion of gasoline and oil in a ratio of 25: 1.

The doubled consumption of engine oil is compensated by its lower cost. According to the assurances of the developers, original components are introduced into the composition of Chinese oils, which help to increase the wear resistance of power units and the real extension of their assigned resource.

According to the conclusion of independent experts, the quality of the best brands of Chinese motor lubricants corresponds to those of European manufacturers in the middle price range. This is the level of branded motor oils of the Standard group and partially. Super.

Recommended brands of fuels and lubricants for powering chainsaws

The specific brand of gasoline for the saw is always given in the manufacturer’s instructions. It is recommended to strictly follow it.

There are 2 types of oil:

  • For engine,
  • For lubricating the chain and bar.

DO NOT confuse or misuse them. This is guaranteed to damage the tool. Repairing it can cost almost as much as a new saw.

The most popular chainsaw lubricating oils are:

Each container with branded oil always indicates the proportion of oil and gasoline for a chainsaw (Stihl, Husqvarna, Partner, Ural), which must be adhered to when making a mixture.

Benefits of branded oils

Many domestic and foreign manufacturers specialize in the production of Special motor oils, but the highest ratings are in the branded products of Stihl, Husqvarna and Makita.

Domestic engine oils of the LUKOIL brand are inferior only in certain parameters of the branded assortment.

The list of advantages of branded motor oils:

  • Economical consumption;
  • Stability of performance under difficult operating conditions and during long-term storage;
  • The minimum amount of toxic compounds in exhaust gases;
  • Almost complete absence of carbon deposits.

According to the American classification, API-TB oils can be used for work in household and professional models. The Japanese counterpart is JASO-FB and JASO FD. Preparation of a combustible mixture using oil for 4-stroke engines is strictly excluded.

Red, green or any other color of oil determines the product’s belonging to the assortment of a certain manufacturer, therefore, when determining the characteristics of the material, it is not taken into account. You should be extremely careful when choosing engine oil of unknown composition and origin.

To obtain additional information on quality and operational parameters, it is better to temporarily refuse to use such material.

It is allowed to mix engine oils of the same type in composition and purpose, produced by brands known for the quality of their assortment. Under no circumstances is it allowed to mix mineral and synthetic oils.

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.

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

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. Under no pretext DO NOT use working off even as a chain lubricant. This will lead to the fact that soon it will be necessary to repair the tool.

Proportion Of Oil Gasoline For 2 Chainsaws

Petrol

The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92.

  • The opinions of experts on the use of different brands of gasoline 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 if you are fully confident 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.

There are also irreversible changes in the operating parameters of the fuel when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance.

Proportions of oil and gasoline for Carver chainsaw. Self-selection criteria

A wide range 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. Consumables 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 instruction manual. In particular, Stihl and Husqvarna engine oils are completely interchangeable in composition and application.

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.

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.

The proportion of oil and gasoline for a chainsaw: how to dilute

All modern chainsaws are equipped with a two-stroke engine. Its long and trouble-free functioning directly depends on whether the proportion of oil and gasoline is correct for the chainsaw. The variety of tool brands and the features of each of them are a prerequisite for the fact that this procedure is not easy for most novice users of chainsaws.

Step by step instructions for refueling

If you want to refuel your chainsaw, you need to follow a simple algorithm:

Why you need to mix oil and gasoline

When using the saw, gasoline should always be mixed with oil. The reason for this is the design features of a two-stroke internal combustion engine. It does not have a dedicated lubrication system for parts (as in other GIS) and, accordingly, its cylinders with O-rings, crankshaft, bearings and connecting rods Must be lubricated directly in the process of obtaining fuel.

The ratio of the amount of oil and gasoline for the fuel mixture

The proportion of oil and gasoline for a chainsaw is usually made up according to two recipes:

  • 50 servings of gasoline per serving of engine oil
  • 40 servings of gasoline per serving of engine oil

If the chainsaw was recently purchased and has NOT yet been operated, then the fate of the lubricant is increased by a quarter. The same amount is poured into fuel when cutting at temperatures below 2 degrees.

It is NOT difficult to get such a mixture. Almost every modern saw is equipped with a special two-section container. Oil is poured into a smaller part of it, and gasoline is poured into a larger part. The lids of both parts are tightly twisted and the container is turned over, shaken thoroughly. This achieves a complete and homogeneous mixing of both components.

If there is such a special container, then you can use any gasoline-resistant plastic container with a one liter lid and a disposable syringe for 5-10 cubes. The gasoline tank must first be cleaned of various pollutants and water. After that, one liter of 92-95 gasoline is poured into it.

In parallel, 20 ml of oil is drawn into the syringe. If filling is done in cold weather, then you need to take 24-30 ml. Gently pour it into a container with gasoline. It is tightly closed with a lid and shaken thoroughly until the components are completely mixed.

  • Husqvarna
  • Kreissman
  • Sadko
  • Stihl

What will happen if you pour working off into a chainsaw

When the owner of the chainsaw has been using it for a while, they may want to do some modification to the tool. And it’s good if his desires are limited to the purchase of various attachments that expand the functionality of the chainsaw. But some go further. they start experimenting with the gasoline and oil that their saw runs on.

If in gasoline we have already spoken earlier (most modern dust requires it with a high octane number. not lower than 92-95), then in oil it is worth mentioning separately. In many motorists, a significant amount of used engine oil accumulates during the operation of a car. And therefore, some have a desire to use this material for refueling a chainsaw.

If this is done, then it is guaranteed that the engine will fail. This is primarily due to the low lubricity of the recycled oil. It will burn with a lot of black soot. The metal particles contained in the oil will first clog the fuel filter (these are particles that are larger), and then the cylinder O-rings will fail. A metal suspension in the oil will damage both the surface of the cylinders themselves and the bearings.

Some “innovators” try to use the working off to lubricate the chain itself and the block on which it is located. It also will NOT lead to anything good. What exactly will happen can be seen on the attached.

Consequences of violation of the ratio

How accurately you will observe the proportions of the oil-gasoline mixture recommended by the manufacturer depends on the service life of the motor scooter engine. 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, but somewhere it will not be enough at all, the parts touching 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 towards the lack of oil. It is better to pour a little oil 10 times than not to top up just once. 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 the event of a failure of the lawn mowers, 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, we recommend that you look for another trimmer model in 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 probable fuel mixture components for a two-stroke engine. Basically, for THESE units, AI-92 gasoline and a special synthetic oil are used, which contains a solvent for better mixing with fuel. This oil evaporates slowly and has the ability to completely burn out in the cylinder, Do not leave carbon deposits.

The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline need 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 rates when preparing fuel for the trimmer. When using mineral oils, a 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 working with lawn mowers, 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 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 variants of lawn mowers running on AI-95 gasoline. This should also be considered.

Gasoline to lawn mower oil ratio

lawn mows are a fairly common technique for combating weeds in summer cottages, in road gardens and housing and communal services. These devices have two more names. 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, and 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 manually, 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 issue of the correct refueling of two-stroke lawn mowers, 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, which many owners of this mowing unit “sin” with. The following actions are considered as mixing errors.

  • Adding oil to the fuel already in the mowers’ gas tank. Similarly, a homogeneous fuel mixture will NOT work. Perhaps it will work, if only then shake the trimmer for a long time. But it is unlikely that someone will do this by taking the weight 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 much more energy will be required than if it were done the other way around. pour oil into the filled gasoline.
  • Ignoring accurate 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 be dissolved in gasoline.

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

  • Use only clean containers made of metal or special plastic for storage of gasoline, oil, ready-made fuel mixture and its preparation.
  • Use for filling gasoline into the LEIKOME dilution container in order to avoid spilling, and for adding oil. in 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 the entire amount of oil required to prepare the mixture to the gasoline.
  • Mix the contents of the dilution container thoroughly. It is best to stir by making circular movements with a tightly closed container. You should 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 an ingredient in the mixture, how clean it is.
  • Add the rest of gasoline to the mixed mixture and mix thoroughly again.
  • You can refill the fuel tank of the lawn mowers.

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

How to choose for lawn mowers?

For two-stroke engines, lawn mowers 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 which gasoline the trimmer should work, you can choose it 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 and or another model of the unit “likes” 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 in the equipment manufacturer. 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. In the choice of standard proportions for lawn mowers of European and American manufacturers in connection with the type of oil, we have already told you earlier. According to the class of oils for household trimmers, you need to use TB oil according to the API classification. For more powerful. class TS.

For the ratio of gasoline to oil required for lawn mowers, see the following.
