Husqvarna what gasoline to fill

If you don’t know how to start the STIHL chain saw 180 “in the cold”, you should strictly follow the manufacturer’s recommendations and requirements, following the algorithm:

  • Switch on the ignition (to find out how to set the ignition on the STIHL 180 chain saw, see the manual).
  • Set the control lever at its lowest point (this way, the carburetor flap will block the air from the filter, and the throttle will be fully open and the fuel mixture can be enriched).
  • Pull the starter grip, this should be done several times before the first burst occurs. This will signal that the mixture has gone directly into the cylinder and your machine is ready to start.
  • You can now move the lever one section up, with the throttle remains in the same position and the air vent opens.
  • All you have to do is pull the starter. The STIHL MS 180 chain saw will then work at higher rpm.

If you need to set the choke to idle, simply squeeze the throttle trigger, and immediately release it. The engine speed will return to normal after use.

Fuel mixture for two-stroke engines

Grass trimmers that are equipped with a two-stroke motor do not have a separate system designed to supply oil to lubricate the working parts. For this reason, such devices should not be filled with pure gasoline, but with a mixture of fuel and engine oil. The gasoline used must be specially formulated for two-stroke engines. Use of automobile engine fluid will lead to premature engine failure.

Preparation of fuel mixture for two-stroke engines

You need to fill your two-stroke mower with AI-92 gasoline. If you use AI-95 you may notice overheating of the engine and uneven engine performance. Gasoline and oil in a 50:1 ratio, where 50 is fuel and 1 is oil. It turns out that you need 20 ml of oil per 1 liter of fuel.

If the engine is worn out or the tool works with a high load, the proportion is 25:1. In case there will be little lubricant, the cylinder walls and piston surface will be scuffed. Then the piston ring will be destroyed, resulting in the engine jamming. Too much oil and gasoline is not critical, but it can lead to carbon buildup. The piston ring will get corked, which will reduce the power of the device.

The proportions of oil and gasoline for the fuel mixture

What kind of gasoline to put in a chainsaw of a popular brand

A chainsaw is a handy unit that can solve a lot of household problems. Runs on fuel that must be prepared by yourself just before pouring it into the tank. Those who have purchased a functional device for the first time, are interested in the question of what gasoline to pour into the chainsaw. Avoid damage and prolong the life of the device only if you follow the manufacturer’s recommendations specified in the manual.

Modern brands of chainsaws (Husqvarna, Partner) from foreign manufacturers will work smoothly on gasoline AI-92. it is ideal for the engine

Your owner’s manual may also show the 95 brand, but it should be used with caution. The quality of this gasoline is currently questioned, its octane number is increased with the help of various additives

It is detrimental to the chainsaw engine, which can lead to the overhaul of the machine. And it costs at least half the price of a new model, not including replacement parts.

For devices from domestic manufacturers (Ural, STIHL, Druzhba) gasoline AI-80 is recommended

It is important for the user that its flow rate is minimal

Gasoline and oil ratios

Due to the two-stroke type of engine, fuel is purchased separately in pure form, then mixed with oil designed specifically for this type of engine. Most experienced users mix the substances in proportions of 1:50. In the photo you can see the popular high quality products used to prepare the fuel mixture.

Important points to be observed:

  • domestic chainsaws (Ural, STIHL, Druzhba) work with oil brands M8-B, M-12TPU, M8-B, TP, MGD-14M, sometimes foreign variants are used, the recommended proportion is 100 g of oil in 2.5 liters of gasoline AI-80
  • foreign models (Husqvarna, Partner) operate using foreign-made oils (1:50 or 1: 40), characterized by minimum consumption.

How to prepare the fuel mixture correctly

When buying gasoline for a chainsaw and oil, it is worth thinking about additional accessories. The following tools are used to measure and be able to pour the mixture into the chainsaw:

  • A container for dilution (plastic or metal),
  • syringe,
  • A measuring bottle (will do to measure gasoline),
  • dispenser,
  • watering can (pour into the chainsaw).

A very convenient tool is a special dispenser bottle by STIHL brand (see photo), which allows you to do all the operations accurately and quickly, measuring out the required amount of each substance

When choosing gasoline for a STIHL chain saw (Friendship, Husqvarna, Partner), you should pay special attention to the second component

Oils from different manufacturers have variations in shade. Products manufacturer HP. red, the premium segment “synthetics” is mainly represented by green. If you take the gasoline for your Husqvarna chainsaw, the oil must be of appropriate brand, not cheap (green or blue). You can watch the mixing process in the video.

Useful tips

Experts and manufacturers do not recommend to prepare a large volume of fuel and store it for a long time. Oil and gasoline may “behave” differently in the mixture, it all depends on the brand, quality, degree of additives and additives. Oxidation and crystallization processes occur. The result can be disastrous and cause additional financial expenses for the user: incorrect operation or engine failure.

Fuel is prepared for up to three refills by mixing in containers made of metal or strong plastic. Conventional plastic breaks down, reacts with gasoline, corrupts the fuel composition and creates a risk of sudden ignition.

Gasoline consumption and operating time

An important question is the gasoline consumption of a chainsaw, because the user must understand what to count on.

The volume of fuel tanks is about 0.5 liters. When the power of the device is 2 kW, the consumption of gasoline with oil will be about 1.2 liters per hour. In layman’s terms. a chain saw can operate continuously at maximum speed for about 30 minutes. Less powerful devices have a smaller tank volume, the gasoline consumption is controlled by the owner himself.

Over time, you will learn how to service this household appliance yourself. The main thing is to keep it running and use only quality fuel. It is necessary to mix it safely so as not to damage your health or the environment.

Advantages of a gasoline grass trimmer

Lawn mower with a gasoline engine has several advantages:

  • High power and performance;
  • The possibility of refueling at any time of operation;
  • Possibility to use the rotor attachment for cutting small trees or bushes;
  • Mobility (the ability to use anywhere. on the plot or in the field).

Gasoline-powered mowers come in 0.5 liter, 1 liter and 1.5 liter tanks.

Gasoline mixture requirements for the two-stroke engine

The difference of two-stroke engine is its higher power as compared to four-stroke engine. The combustible mixture for it is prepared in a certain ratio of gasoline and special oil. You can find the optimum oil to petrol ratio for your lawnmower in the owner’s manual. The recommended proportions must be strictly observed. When adding additives the manufacturer took the engine type into account. For this reason, do not mix different oils.

When using mineral oils, the mixing is done in the ratio of 1:25, 1:30, 1:35. Synthetic oils are in the 1:50 or 1:80 ratio. It means that in each of the proposed mixtures, the required amount of oil is dissolved in the volume of gasoline. Mixing gasoline with lawnmower oil is like mixing water with syrup. It is necessary to pour petrol, add the exact amount of oil and shake the mixture. It is advisable to use a fresh solution for work. If stored for more than two weeks, the composition changes and the oil film causes malfunctions in the carburettor.

Do not use PET bottles to dilute and store the combustible mixture. Gasoline destroys plastic, the polymer dissolves in the mixture and then deteriorates the quality of the fuel, there is a risk of stray currents.

What oil to use

When choosing a lubricant the following main factors are taken into account

  • engine cooling, protection against thermal shock
  • operation at high revolutions and under high loads;
  • corrosion resistance during mower downtime in winter
  • absence of soot and sulfate ash, smokelessness;
  • environmental friendliness;
  • good solubility in petrol
  • long shelf life of prepared lubricant.

the oil in the lawnmower must meet the requirements of biodegradability, all-season viscosity and economy.

2-stroke engines require a mix in the manufacturer’s recommended oil to gasoline ratio. For four-stroke engines do not mix, the ingredients are poured separately into different containers. Lubrication is carried out via the oil pipes, pump, filter and valves.

The types of oils used to make the lubricant are those most suitable for 2-stroke units:

The fluid contains 5-15% of various additives to improve efficiency, slow down corrosion and stabilize viscosity.

Lawnmowers with 4-stroke engines require a simple automobile fluid, e.g. SAE30 or 10W40, with the right technical characteristics. An important characteristic of oil for 4-stroke lawnmowers is its long-term stability. The SF formulation is suitable for almost all brands of machines. For winter operation a frost-resistant fluid is used. In the table you can find the right oil grade, which is better to pour into the tank of a mower with a 4-stroke motor to work in certain temperature conditions. For example, mineral engine oil ALKO or Zubr ZMD-4T-M SAE30 class can be used at temperatures from.5 C° to 35 C°, and semi-synthetic Mannol 4-Takt Plus 10W-40 SL with a temperature range of.25 ° C to 40 ° C is suitable for all-season use.

What gasoline to fill in the lawnmower with a four-stroke engine?

And now we will tell you what gasoline to pour into the lawnmower with a four-stroke engine, the main difference is the presence of the crankcase. In it there is oil for motor lubrication, so that the machine of this type will function normally, it is enough to fill it only with gasoline. But it has its own special features. Since the technique does not have an oil filter, which means that it is not cleaned, it should be changed after about every 50 hours of operation.

As for the gasoline you need to fill the mower with, it should not be a higher grade than recommended by the manufacturer of the equipment. The higher the octane number, the longer the fuel burns. This, in turn, can lead to significant problems and premature tool failure.

It is well known that gasoline is highly flammable and its vapors are explosive. With this in mind, we recommend always following a few simple rules to ensure the safety of each user:

  • Let the engine cool down before refueling.
  • Only fill up with 92nd gasoline (not lower);
  • It is forbidden to work with fuel if there is an open fire in the vicinity.
  • To avoid exhaust poisoning, fueling and starting should be done outdoors or in a well ventilated area.
  • 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 heats up.
  • Try not to get fuel on your clothes and shoes.

Husqvarna lawn mowers are lawn care products worthy of the name

Countryside maintenance equipment is available in a wide range. Husqvarna lawn mower is one of the best models at an affordable price. The highest quality products in any price category. a distinctive feature of Husqvarna, which is a world leader in the production of tools with diesel and electronic traction.

Filling up the equipment

What petrol to use

Gasoline for lawnmowers is suitable for regular car gasoline, which is sold at all gas stations. Some models are equipped with a motor, working mainly on diesel, but these are quite a few. Gasoline-powered machines are usually sold in shopping malls.

The manual for each machine specifies the recommended brand of fuel to fill the gas tank. That’s why it’s important to look closely at the owner’s manual right after the purchase. This will get rid of a lot of problems and prolong the service life of the equipment.

Additional information. The higher the octane number, the more resistant the gasoline is to detonation. Manufacturers accomplish this by adding different chemicals to the fuel. So the flip side of the coin here is an increased combustion time for brands with a high octane number.

gasoline, fill, husqvarna, lawnmower, fuel

Machine manufacturers create machines with parts that have different tendencies to detonate. That’s why each vehicle has its own petrol. There is no one general recommendation for a four-stroke or two-stroke motor by brand of gasoline. It all depends on the manufacturer and their advice.

If you ignore the instructions and use fuel stored in the garage but not suitable for the unit, it will lead to the following malfunctions:

  • On the plugs, the cylinders will appear fouling;
  • The piston system will fail;
  • The engine will constantly overheat and work unstably;
  • The power of the technique will drop and so on.

How to fuel

It is important not only to understand what kind of fuel to fill the tank, but also how to do it correctly. Depending on the type of power unit, selects the way of refueling. There are two types of internal combustion engines:

Each of them has its own peculiarities. The main difference is in the work cycle. In the first case, the piston takes two strokes per cycle, and in the second case, it takes four. Four-stroke. less expensive in gasoline, oil and more environmentally friendly. This motor element releases fewer exhaust gases. It is more powerful. In turn, on a small plot, you can use the technique with a two-stroke motor. Such models are simpler and cheaper. Grass trimmer, like a lawnmower, has similar types of engines.


In order to fuel this unit, fuel must be prepared. Pure gasoline is no good here. It has to be diluted with oil. The thing is that the two-stroke engines have no extra capacity for oil, so the oil is poured into the engine along with the gasoline.

Lubricant must be plentiful. If you save on it, it will be difficult for the piston to perform the work cycle. Eventually the cylinder and piston wheel will be damaged. This will lead to a change of the engine. If, on the contrary, you pour too much oil, the piston will be covered with carbon deposits, and the power of the equipment will decrease many times.


Such an engine has a complicated design. In addition to the tank, there is a special container for oil. It’s called a crankcase. During operation, fuel and lubricant are fed in the right proportions to the motor. The advantage of a four-stroke engine is that there is no burning oil smell like a two-stroke engine.

The fuel tank must be filled with pure quality raw materials of the brand intended for the machine. Usually it is gasoline AI-92, AI-95. Fill as required. There is a mark in the petrol tank up to which the liquid is poured. If there is no free space, the tank must not be filled as much as necessary. It is important to leave enough free space. Otherwise the engine will not run properly.

Mower oil

Choosing the right oil for your gardening equipment should be based on the technical specifications of the machine. The oily fluid is necessary so that it can spread out in the spaces between parts and on the parts to make them slide smoothly. This keeps wear and tear to a minimum.

Please note! Lawn mower oil for 2-stroke engines is categorically not suitable for machines with a 4-stroke engine. Due to confusion, you can lose the warranty and break the engine.

According to the characteristics of the oil 4 x tact for lawnmowers should retain its chemical and physical properties for a long time, as it does not burn during the engine operation, and continues to move the mechanism. The oil for a lawnmower with a 2-stroke engine is in turn burned with the fuel. The oil level is the amount of soot particles in the brake fluid. When using a quality product, the fouling should be minimal.

Important! Do not purchase automotive oils. Lubricants for passenger cars and commercial vehicles are designed for use in water-cooled machines. Lawn mowers, like snowmobiles, power tillers, are air-cooled. Because of these differences, manufacturers make their own products for garden equipment. They are oriented to air cooling.

For two-stroke engines

Lubricants are suitable for two-stroke engines:

The packaging should indicate the type of engine for which the product is suitable. Machine manufacturers often indicate the recommended lubricant varieties in the instructions for use. The manufacturer advises the brand, based on the appropriate viscosity level, which is acceptable to this unit.

For four-stroke engines

An oil marked SAE-30, SAE 20w-50, 10W-30 is suitable for four-stroke engines. These numbers and letters define the oil’s peculiarities, more exactly its viscosity and permissible weather conditions. The first two options are suitable for work in the summertime. The third option is preferable for cool off-season. Product labeled 5W30 may be used. It is an all-season fluid. If the internal combustion engine is 4-stroke, the advantage is given to a semi-synthetic or mineral product.

Further information. Some gardening equipment companies state in the instructions that you should only buy brand name oil with the company logo on it. These products are more expensive than conventional products.

Gardeners get confused: which lubricant to buy? Employees of repair services explain that it is not necessary to buy branded oil. Companies that specialize in the production of equipment do not make their own lubricants. They buy it from specialized suppliers, and then pour it into containers with their own labels. That’s why it doesn’t matter what brand name is on the can, the main thing is to buy a product that perfectly matches the parameters of the engine.

How to fuel and maintain four-stroke engines

For 4T engines, gasoline does not need to be mixed with oil. But you should use only the gasoline type recommended by the manufacturer. This is because with different octane numbers, the combustion rate is very different, while the ignition system is set to a specific time value. Also different combustion temperature: piston and cylinder materials may simply not be designed for it.

What’s really important when operating four-stroke motors is to keep an eye on the oil level in the crankcase and to renew it periodically. Most engines have a dipstick in the oil filler plug, on which marks are printed the minimum and maximum permissible oil levels. Oil from the crankcase goes into the cylinder in microscopic portions and burns there, respectively, its level in the engine gradually becomes lower. this phenomenon is absolutely normal, but the consumption rate should not exceed the limit set by the manufacturer.

a complete oil change is necessary after a certain interval in engine life. If the manual does not specify this indicator, you can assess the oil quality visually. The darkening of the lubricant is not a reason for changing it, some soot is inevitably accumulated in the crankcase of a four-stroke engine, so that the oil turns black even after a few hours of operation. Keep an eye on the clarity: Cloudy or shiny specks of metal chips are the basic prerequisites for flushing and changing.
