The mix is 1:40 for stihl oil and 1:25 for other branded oils.
A Stihl chainsaw typically runs on a fuel mixture of 50:1, which means 50 parts gasoline to 1 part 2-stroke engine oil. This ratio ensures optimal performance and lubrication for the engine. However, it's important to check the specific model's manual, as some older models may require different fuel mixtures, such as 40:1. Always use high-quality unleaded gasoline and the recommended oil for the best results.
I recommend 40:1 with good quality oil.
For the 1995 model 40 hp Evinrude, mix at a 50:1 ratio.
40:1 with high quality 2-stroke oil mix would be fine. http://store.chainsawr.com/
