Your petrol linetrimmer runs on a fuel mixture made up of petrol and engine oil. Use the right blend to keep tools at their best for years to come.

It’s important to power your linetrimmer or brushcutter with a fuel mixture made to the right recipe: unsuitable fuels and the wrong mix ratios can cause serious damage, leading to piston seizure, excessive wear, and ultimately a shorter lifespan for your linetrimmer. The mix ratio you need to remember when making up fuel mixture for your trimmer is:
1:50 = 1 part oil + 50 parts petrol
Any two-stroke oil you use in your linetrimmer must have the TC classification, and you can use the same ratio for your fuel mixture as with the STIHL engine oil:
1:50 = 1 part oil + 50 parts petrol
You can achieve a fuel mix ratio of 1:50 with 5 l of petrol and 0.1 l (100 ml) of oil.
You should only use high-quality oil for 2-stroke engines, that meets the requirements for TC classification. We recommend STIHL 2-stroke engine oil, which is specially formulated for STIHL tools and will prolong the life of your grass trimmer.
Caution: Inferior products can damage the engine, sealing rings and fuel tank of your trimmer.
Information on mixing: Make your fuel mixture in a vessel that is approved for use with fuels. Pour in the oil first, followed by the petrol; seal the canister and give it a good shake to combine the fuel mixture. Now you’re ready to use the fuel mixture in your linetrimmer or brushcutter tank. Carefully open the canister, in case pressure has built up inside.
Using unsuitable fuel or an inappropriate mix ratio could damage your linetrimmer. The easy way to give your STIHL tools the best treatment is by opting for STIHL MotoMix fuel, a premixed fuel mixture that contains no ethanol, is specially formulated for STIHL tools and guarantees high performance and a long service life.
