Mixture Calculator
How do you calculate the fuel mix for a 2-stroke engine?
Oil = petrol × P / 100, where P is the percentage stated on the engine. Example with a 50:1 ratio → P = 2% → 10 L of petrol × 2 / 100 = 0.2 L (200 ml) of oil.

How the Gasoline-Oil Mixture Calculator Works
The gasoline-oil mixture calculator is an essential tool for those who use two-stroke engines like chainsaws, brush cutters, vintage scooters and enduro motorcycles. This tool allows you to precisely calculate the exact amount of oil to mix with gasoline, ensuring proper engine operation.
What is the Mix Ratio?
The mix ratio indicates how many parts of gasoline are needed for each part of oil. For example, a 50:1 ratio means 50 parts gasoline for 1 part oil.
