What it is
Stihl MotoMix is ready-mixed fuel at 1:50 for two-stroke and Stihl 4-MIX engines, in a 5 litre can (part 0781 999 6301). The listing says it suits all Stihl engines, contains no ethanol and has a five-year shelf life. When we checked in October 2026, it couldn’t be dispatched to our location.
Why ready-mixed?
Most small-engine starting problems come from old or badly mixed fuel. Ethanol in pump petrol absorbs water, separates and attacks carburettor diaphragms; mixed fuel goes stale within weeks. MotoMix avoids both: it’s ethanol-free and keeps for years, so a machine you use a few times a season starts as easily in spring as it did in autumn. See ethanol petrol and brush cutters.
Is it worth the price?
It costs several times more than mixing your own. It makes most sense for occasional users, for machines stored over winter, and for anyone who wants to avoid mixing errors. Heavy users usually mix their own with fresh E5 petrol and a good oil such as Stihl HP Super.
Use only at 1:50
Check your manual: most current machines run at 1:50, but some older or budget engines need 1:25 or 1:40. Four-stroke engines with their own oil sump take plain petrol, not MotoMix. Compare options, including Aspen 2, in the best 2-stroke oil and fuel.
