I use 40:1 mixed with high quality 2-stroke oil. I have used this mix in 1000s of chainsaws without any problem.

25 to 1 is the mixture for the fuel
The fuel ratio for a Stihl MS250 chainsaw is typically 50:1, which means 50 parts gasoline to 1 part oil. It's important to use a high-quality two-cycle engine oil that is specifically designed for outdoor power equipment. Always follow the manufacturer's recommendations for the fuel mixture to ensure proper engine lubrication and performance.
