E10 fuel has been introduced throughout the EU to preserve crude oil stocks and combat climate change. What the abbreviation E10 means: “E” stands for ethanol, which is mixed with petrol. The number 10 indicates that the mix contains a maximum of 10% ethanol. Standard four-star petrol which has a maximum of 5% ethanol will continue to be available. You can find E10 fuel by looking for the “NormalE10”, “SuperE10” or “SuperPlusE10” labels at the pump.
E10 fuel is suitable for all STIHL chainsaws and power tools driven by engines from Briggs & Stratton, Kawasaki, and Kohler. Your carburettor may have to be adjusted to compensate for the altered composition of the fuel. Contact a STIHL dealer for help and advice.
STIHL recommends that two-stroke fuel mix prepared with E10 fuel is stored for no longer than 30 days to minimise phase separation. Phase separation of these mixes can occur when ethanol absorbs moisture from the air and settles on the bottom of the canister; this phenomenon can stop the engine from running. Phase separated fuel is no longer usable even after it has been well shaken.
In short, unsuitable fuels and lubricants, or a non-standard fuel-oil mix ratio may damage your engine. STIHL MotoMix and STIHL Moto4Plus fuels are always the right choice, as they are specially designed for our engines and guarantee high performance and a long service life. And what’s more, these fuels can also be stored for long periods, unlike conventional fuel from the petrol pump.
