The stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.
Mixing 2-stroke

For example, if you need to mix 5 litres of 2-stroke fuel at a 50:1 ratio, you will need 5 litres of petrol and 100ml of oil.

For a mixing ratio of 1 : 50 you need 5 litres of high-octane gas and 0.10 litres (100 ml) of STIHL two-stroke oil.
1:25 = 1 part oil + 25 parts petrol, or 40 ml oil per litre of petrol when using other brands of oil. Any two-stroke engine oil you use in your petrol gardening tool must have the TC classification.
The science behind air fuel ratio

The scientifically “perfect” mixture for normal petrol is 14.7:1, that is 14.7 times the mass of air to fuel. However, that doesn`t mean a car should run at that. For optimum fuel economy 16-17:1 is usually best, leaner than that and the car will begin to misfire.

Mixing ratios

For a mixing ratio of 1 : 50 you need 5 litres of petrol and 0.10 litres (100cm³) of STIHL two-stroke oil.

100:1 – Mix 50ml of oil per 5ltrs of fuel.

Recommended by Yamaha and Suzuki for most of their small two stroke engines up to about 30hp, this ratio requires the least amount of TCW3 two stroke oil. The result of using this ratio (less oil) is reduced spark plug fouling and less smoke.

For a mixing ratio of 1 : 50 you need 5 litres of petrol and 0.10 litres (100cm³) of STIHL two-stroke oil.

What is fuel mixture for solo motosage 60135
ANSWER : Some say 100:1 with synthetics. I use synthetics on 80cc and larger saws in the range of 40/50:1. I never go higher than that….saws are just too expensive to be stepping over dollars to pick up pennies. A lot of people are trying to make mixing ratios like some kind of mystery voodoo. You’ll always be fine in the 40/50:1 range with a good synthetic oil.

Roundup superconceterte mixing – Roundup "" Weed & Grass Killer
ANSWER : I assume you are talking mixing ratios. In most cases a 1% roundup to water mixture will kill many plants. On very stubborn species you can go to a 2% concentrate but anything above that in my opinion you’re just wasting your money. More isn’t always better when it comes to weed killers.
