Which Gasoline Is Poured Into The Stig Lawnmower

First bought a lawn mower with an internal combustion engine? Not sure which fuel to pick? In the article, we consider the brands of gasoline sold on the Russian market. You will learn how to make a choice, whether it is possible to save on the octane number, and how to extend the tool life.

Fuel selection

Which Gasoline Is Poured Into The Stig Lawnmower

Preparation of fuel for a two-stroke engine consists in mixing special engine oil (it is bought in the same place as lawn mowers or spare parts for cars) with gasoline. Mineral oil is mixed with fuel in a ratio of 1 to 32 (or 1 to 35), and if it is synthetic, then a ratio of 1 to 50 – all this should be indicated on the package. You can prepare fuel for the lawn mower for the whole season, for this, 100 g of oil is added to the 5-liter canister of gasoline.

To the question: “What gas to use?” – the answer is simple: the brand should not be higher than that indicated by the manufacturer of the lawn mower. The octane number matters – the higher it is, the longer the fuel burns, if you use a higher grade fuel, this will reduce the operating time of your device. The four-stroke engine has a crankcase, which contains lubricant that lubricates the motor, so it is only refueled with gasoline. But it will have to be changed at intervals of 50 hours, whatever it may be, since there is no special oil filter.

Only a cooled engine can be refueled, and the tank cannot be filled to capacity, you need to leave a little space for expansion. Of course, safety rules must always be followed.

Which pour gasoline a four-stroke engine mower?

Now tell what gasoline pouring into a four-stroke lawn mower, the main difference of which is the presence of a crankcase. It contains oil for lubricating the motor, because in order for this type of apparatus to work normally, it is enough to fill it with gasoline only. But there are some peculiarities. Because the equipment does not have an oil filter, which means it does not clean, you need to change it approximately every 50 hours of operation.

Preparation of a fuel mixture for two-stroke engines

The video shows how to make a fuel mixture for two-stroke engines. Refueling mtkosa, chainsaws and.

As for gasoline that needs to be refueled, the mower should not be of a higher grade than recommended by the manufacturer of the equipment. Since the higher the octane number, the longer the fuel burns. And this, in turn, can lead to significant problems and premature failure of the tool.

It is well known to everyone that gasoline is a highly flammable substance and its vapors are explosive. Based on this, we recommend that you always follow a few simple rules that will ensure the security of each user:

  • Allow the engine to cool before refueling.
  • Do not work with fuel if there is an open flame nearby, and smoking is also prohibited.
  • In order to avoid poisoning by exhaust gases, fill in fuel and start up should be outdoors or in a room with good ventilation.
  • It is not recommended to fill the tank completely, it is necessary to leave a place for the "expansion" of gasoline, which always occurs when it is heated.
  • Try not to get fuel on your clothes and shoes.

In general, maintenance of gasoline engines lawn mowers – A fairly simple matter that does not require you any special knowledge and skills. For units with a two-stroke engine, you need to learn how to properly prepare the combustible mixture, and also clean the air filter in a timely manner. For devices with a four-stroke engine, it is enough to change the oil annually and clean the air filter so that it serves you for many years faithfully.

The choice of gasoline, depending on the type of engine

When buying, check with the seller what motor the tool is equipped with. Oil requirements for two-stroke and four-stroke engines are different.

A four-stroke lawn mower does not require fuel pretreatment. The design provides two tanks for gasoline and oil. Use the oil recommended by the manufacturer to extend the life of the tool.

Use two-stroke engines with a mixture of engine oil. The proportion of the composition is indicated on the gas tank cap. To understand how much oil needs to be added, see table.

Type Required Proportion
Mineral 1:32 – 1:35
Synthetic 1:50

Example calculation using a synthetic product:

  • Tank volume – 1 l;
  • The amount (1000 ml) divided by 50 (see the proportion in the table);
  • The total value is 20.

So, per liter, you need 20 ml of synthetic oil. If it is not possible to measure the desired volume – prepare a larger amount of the mixture. For example, for a 5 liter canister, half a faceted glass of synthetic oil is enough. Excess can be stored in the canister all season, the quality will not deteriorate.

The emergence of lawnmowers on sale has greatly facilitated work on the care of grass on lawns. Depending on the engine model, they are divided into 2 types: gasoline and electric. If you choose between these options, then gasoline is preferable, since it is much more mobile – it does not require wires and an electrical outlet.

In order for the lawn mower to help care for the lawn for as long as possible, you need to carefully monitor its condition and regularly carry out maintenance.

The amount of oil per liter of fuel

Two types of engines are installed on gas mowers – four-stroke and two-stroke. There are significant differences between them. The first option has a separate supply of oil and gasoline, that is, there is no need to prepare a special fuel mixture. And the second type of motors requires constant lubrication of engine parts by mixing fuel and oil in a certain proportion.

If you purchased a grass mowing tool with a two-stroke cycle of the engine, then you have to do the preparation of the fuel composition to refuel the mower.

The fuel mixture consists of gasoline and special oil for engines with a two-stroke cycle. When choosing oil, it is advisable to use lubricant from the same manufacturer as the lawn mower, but this is not a fundamental issue.

Two-stroke engines can be distinguished from others by marking on the label. It also indicates the ratio in which it is necessary to dilute the lubricant with the fuel. When using good and high-quality oils, the dosage, as a rule, is: 1 part of oil to 50 parts of fuel, that is 2% of the total volume of fuel. Some owners get confused in these proportions. In fact, everything is very simple.

If the label indicates 50: 1, this means that 5 grams of gasoline needs to be poured 100 grams of oil. In other words, 20 grams of oil is required per liter of gasoline to lubricate the engines.

Rules for the preparation of the fuel solution

Before starting work, you should carefully study the instructions. In no case do you need to do everything “by eye”. Each manufacturer adds its components to the fuel, so it will be useful to familiarize yourself with its recommendations.

The basic rules for preparing fuel for a two-stroke lawn mowing lawn are as follows.

  1. Strictly observe the proportions when preparing the fuel solution. If the concentration of the lubricating component is insufficient, the piston and cylinder will become very hot, and the engine may fail under such conditions. Due to overheating, barbs appear on the cylinder walls, which subsequently will require serious investment in repairs.
  2. Do not add excess oil to the mixture. A large amount of it will lead to the appearance of additional soot and a speedy reduction in engine life. Elimination of defects is also expensive, as is the case with oil savings.
  3. Long-term – more than one month – storage of the fuel mixture is not recommended, since it begins to decompose and lose its basic properties. The prepared mixture can be stored for no more than 90 days, clean fuel is even less – about 30.
  4. Carefully monitor the cleanliness of the combustible solution, protect it from various debris and other pollutants, which could damage the engine.
  5. After completion of work, if a long break is ahead, it is better to drain the fuel mixture from the tank.

Before preparing the fuel mixture, you should take care of its safety in the future. It is better to store gasoline in a metal container, the fuel content in plastic canisters specially designed for this is allowed. In no case should you store gasoline in plastic bottles: the fuel enters into a chemical reaction with polyethylene and decomposition products if it enters the carburetor can disrupt its operation.

Fuel mixture preparation

Many manufacturers of mowers are already supplied with special containers for gasoline and oil with measured marks. But in order to more accurately mix lubricant and fuel, it would be better to use a syringe.

For operations to prepare a mixture of gasoline with oil, simple equipment will be required:

  • Watering can;
  • A medical syringe or measuring cup;
  • Capacity of one liter;
  • Oil suitable for two-stroke engines;
  • Petrol.

First, with the help of a watering can, gasoline is poured into a liter container. For the fuel solution, it will be correct to use the brand of gasoline that is indicated in the instruction manual, since fuel with a lower octane rating can ruin the engine.

Next, we collect the oil, observing the proportion, and pour it into the fuel. Gently mix the mixture – the fuel solution is ready.

After adding oil to the fuel, the mixture acquires a special color, which in the future gives you the opportunity to distinguish the finished fuel solution from pure gasoline.

Do not prepare a large fuel mixture – manufacturers of lawn mowers do not recommend this.

Characteristics of erroneous use

The use of contaminated or improperly diluted solution often leads to serious malfunctions. To prevent this from happening, you need to carefully monitor some engine indicators:

  • Rapid contamination of the fuel filter;
  • The appearance of dirt and various deposits in the carburetor, which will interfere with normal operation.


Applying the above recommendations, you can independently prepare a high-quality fuel mixture for a two-stroke engine. It will ensure the continuous operation of the gas mower for a long period, and also help protect the engine from significant malfunctions.
