Question: what is the ratio for 2 stroke mix?
Answer: Mixing 2-Stroke Fuel. Need to mix fuel for your STIHL 2-Stroke engine? You'll need STIHL 2-Stroke oil, an empty and clean fuel can & fresh unleaded fuel from a reputable petrol station. Mix at 50:1 (20mls oil per 1 litre fuel) when you're using STIHL 2-Stroke oil.
