How To Measure 2 Stroke Oil To Petrol?

It’s critical to understand your engine’s 2 stroke mix ratio. The first thing you should do is look over the instruction booklet that came with your equipment. It should inform you of the proper percentage for your 2-stroke mix.

If you can’t discover the exact ratio for your mix, a 40:1 ratio is commonly used for two-stroke engines. This is 125 milliliters of two-stroke oil to 5 liters of gasoline.

How can you figure out how much 2 stroke oil per litre is?

Because each engine has different requirements, the exact 2 stroke oil ratio is determined by your manufacturer’s specifications. If you’re unsure, a 40:1 fuel ratio for a two-stroke engine is a good starting point. This equates to 25 milliliters of two-stroke oil per litre of gasoline.

The two-stroke mix ratio is determined by the equipment’s year of manufacture and/or make.

Your oil mixture should be as precise as possible, with neither too much nor too little oil.

If you put too much in, the engine will stop, carbon will build up, and smoke will be produced, all of which are terrible for the environment. However, if you put in too little, it will permanently damage your engine and cause it to overheat.

What is the formula for calculating the 2-stroke fuel ratio?

Use a 40:1 oil mix ratio for two-cycle engines. One gallon of gasoline plus 3.2 ounces of two-cycle engine oil Are you unsure how old your equipment is? Utilize the 40:1 ratio.

In Litres, what is a 50:1 mix?

When using STIHL 2-Stroke oil, mix 50:1 (20ml oil for 1 litre fuel). You can add STIHL fuel stabiliser to your 2-Stroke fuel mix to improve the shelf life of the fuel by up to 12 months. 5 litres of fuel can be treated with 15ml of STIHL fuel stabilizer.


There are (8 + 1) or 9 pieces if your mix ratio is 8:1, or 8 parts water to 1 part solution. The percentage of mixing is 11.1 percent (1 divided by 9).

There are (4 + 1) or 5 parts if your mix ratio is 4:1, or 4 parts water to 1 part solution.

The percentage of mixing is 20%. (1 divided by 5).


For example, if your percentage is 4%, multiply it by 1004 (96) to get a 96:4 mix ratio, which can then be lowered to 24:1.

If your percentage is 10%, multiply it by 10010 (90) to get a 90:10 mix ratio, which can be decreased to 9:1.

How much oil does a two-stroke engine require?

Calculator for 2-Stroke Oil Mixtures Use 2.6 fluid ounces of oil per gallon of gas for a 50:1 ratio of gas to oil. Use 3.2 fluid ounces of oil per gallon of gas for a 40:1 ratio. Use 4 fluid ounces of oil per gallon of gas for a 32:1 combination.

Which 2-stroke mix ratio is the best?

A 50:1 chainsaw oil mix ratio is recommended for most 2-stroke chainsaws. However, some experts advise a 40:1 ratio. Older two-stroke machines may even require a 32:1 ratio. It’s a pain to untangle the many instructions and mix several fuel containers, especially for professional landscapers who operate multiple pieces of equipment. We’ll go over chainsaw oil mix ratios, a solution for mixing several fuel cans, and what we think is the best 2-stroke oil for your chainsaw in this post.

What is the 2-stroke petrol strimmer’s mix?

If you’ve just bought a new brushcutter or borrowed one from a friend, starting it up for the first time can be intimidating.

This instruction will show you how to properly fuel a petrol-powered brushcutter, which requires a mixture of gasoline and engine oil.

The quality of both of these is crucial to the engine’s efficient operation and longevity.

Unsuitable fuels or wrong ratios can cause major engine damage, such as piston seizing and excessive wear, therefore please carefully follow the recommendations below.

Safety first

There are a few things you should think about before filling up your strimmer for safety reasons:

  • Because gasoline is extremely flammable, avoid using it near open flames. Also, take extreme precautions to avoid spilling any fuel. It’s best to fuel your machine at least 3 meters away from where you’ll be starting it up.
  • Before refueling, the engine must be totally turned off. Before filling up, ensure sure the engine has cooled down.
  • When opening the tank cap, make sure to do it slowly to enable excess pressure to escape and prevent petrol from spraying out.
  • Only refuel in a well-ventilated environment.
  • Take additional caution when fueling to avoid spilling any on the ground or on yourself. If this happens, you must clear it up right away.

Mixing the correct ratio of fuel

If you’re using 5L of gasoline, for example, you’ll need 0.1L (100ml) of 2 Stroke Oil.

Pour the 2 Stroke engine oil into a mixing can that has been certified for use with fuel, then add the gasoline. Shake the can to properly combine the ingredients. When opening the can, be cautious because pressure may have built up within.

How to fill the brushcutter with fuel

Place the brushcutter on a smooth, clean surface. Place it so that the tank opening is facing up.

Raise the tank cap flap, then remove the cap by turning it anti-clockwise as far as it will go.

Fill the tank slowly and carefully with the fuel mixture, being careful not to spill any.

Reinstall the filler cap and crank it clockwise until it stops, then fold the cliplock down. This will help to prevent the chance of an inadequately fastened cap loosening or coming off and spilling fuel due to unit vibrations. Check for leaks and do not start the engine if one is found. This is a major fire hazard that could endanger people’s lives.
