How To Mix 2-Stroke Fuel

Mix 2-Stroke fuel in 3 easy steps

Need to mix fuel for your STIHL 2-Stroke engine? Follow our three easy steps to ensure you get the perfect mix. 

Step 1: You’ll need STIHL 2-Stroke oil, an empty and clean fuel can and fresh unleaded fuel from a reputable petrol station.

Step 2: Mix at 50:1 (20mls oil per 1L fuel) when you’re using STIHL 2-Stroke oil. If you’re mixing a larger quantity, check out our useful mixing chart.


Step 3:
To prolong the life of your 2-Stroke fuel mix you can add STIHL fuel stabiliser which will extend the fuel’s shelf life up to 12 months. To treat 5L of fuel you’ll need 15ml of STIHL fuel stabiliser.
Note: Petrol has a limited shelf life (as low as 30 days), so always mix with fresh, regular unleaded, purchased from a reputable large volume fuel supplier.
