Oil mix ratios explained
If your manufacturer recommends a 50:1 fuel/oil mix, it means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as shown in the chart below.
What is the ratio for mixing oils?
Common gasoline and oil mix ratios are 50:1 and 40:1. Meaning there is 50/40 parts gasoline to one part oil when mixed. The lower the mix ratio number the more oil per volume in the gasoline. To mix properly add oil to your gas can, then add fresh gasoline from the pump.

What happens if you mix too much oil in a 2 stroke?
What happens if the mixing ratios in a 2 stroke engine are incorrect? If you put too much oil, it can generate additional carbon build-up, making it difficult to start the engine, blow excessive smoke which is particularly bad for the environment and may (with time) cause the engine to stop operating correctly.

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.
Do 2 strokes burn more fuel?
Compared to four stroke engines, two strokes are lighter, more efficient, have the ability to use lower-grade fuel, and more cost-efficient. Therefore, the lighter engines results in a higher power-to-weight ratio (more power for less weight).
Why do 2-strokes not last as long?
Two-stroke engines don’t last nearly as long as four-stroke engines. The lack of a dedicated lubrication system means that the parts of a two-stroke engine wear a lot faster. Two-stroke oil is expensive, and you need about 4 ounces of it per gallon of gas.
Why do they not make 2-strokes anymore?
Answer: Two-strokes left the market because they could not meet steadily-tightening EPA standards for vehicle exhaust emissions. The very feature that makes two-strokes attractive—the simplicity of having only three moving parts (crankshaft, con-rod, and piston—was also their undoing.
Why is 2-stroke engine rarely used?
Two-stroke engines are not quite efficient in combustion because of which they have less mileage. The incomplete combustion is one of the reasons they produce less mileage and because of the other stroke that occurs that unburnt fuel is also passed out to the exhaust increasing the inefficiency even more.
Why are 2 strokes so fast?
Because combustion takes place with each revolution of the crankshaft with a 2-stroke, this format puts out more power than a 4-stroke engine and the power has more instantaneous delivery. This are some reasons why 2-stroke engines have a long history of use on many different types of motorcycles.
