A Stihl chainsaw is a powerful tool. It helps in cutting trees and wood. But to work well, it needs the right fuel. This fuel is a mix of gasoline and oil. Let’s learn more about this fuel mix.

For a Stihl chainsaw, the fuel mix ratio is important. The right mix is 50 parts gasoline to 1 part oil. We call this a 50:1 ratio.
| Amount of Gasoline | Amount of Oil |
|---|---|
| 1 liter (1000 ml) | 20 ml |
| 2 liters (2000 ml) | 40 ml |
| 5 liters (5000 ml) | 100 ml |
