This equation works for any amount of petrol. For example, if I have 5 Litres of petrol I would times 5 x 20 and this would give me a result of 100ml. [links]

This equation works for any amount of petrol. For example, if I have 5 Litres of petrol I would times 5 x 20 and this would give me a result of 100ml. [links]
Here is a recap of the equation: [links]
This gives us a result of 20. here
You will need to divide 1 Litre (1000ml) by the 50 in the ratio (see example below). more
The result we have is 40 which tells us we need 40ml of oil. [links]
Forty to one (40:1) is a pretty easy 2 stroke ratio to calculate, you simply multiply the litre amount by 25.
To make it easier you can use the following old school reference chart. more

For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas.
Similarly, what is the mix for 50 to 1? You want to mix 2.6 ounces of oil to one gallon of gasoline for a 50:1 mixture. If you're mixing up two gallons of gasoline you will have to mix 5.2 ounces of oil to two gallons of gasoline for a 50:1 mixture. more
Likewise, people ask, how do you calculate 40 1 gas oil mix? [links]
So what does 40:1 mean? It’s simply 40 parts of fresh, unleaded fuel with 1 part of semi-synthetic 2 stroke oil. more
Mixing 2-stroke fuel is a process which confuses many people, but is actually incredibly simple if done the right way. With so many machines powered by 2-stroke fuel, especially garden equipment, knowing how to correctly mix it is essential.

Your first step should always be to refer to your user manual to find out what the required ratio of fuel and oil is for the machine in question. For many machines you will have a choice between 25:1 with mineral oil, or 40:1 with semi-synthetic oil. For the purpose of this article, we’ll use semi-synthetic oil.
