110_motomixSTIHL MotoMix® is our patented premixed fuel, specially blended for ultimate performance. Like a sports drink for your engine, this 50:1 mixture of premium non-ethanol, high-octane motor fuel and our highest-quality STIHL HP Ultra oil. Clean and convenient, MotoMix® eliminates the hassle of mixing your own 2-stroke engine fuel while providing superior performance and lubrication. Plus, we stand behind this formulation by doubling the limited warranty when you include MotoMix® with your power tool purchase. STIHL MotoMix® contains no ethanol, allowing it to maintain stability for up to two years after the seal is broken – so it stays fresh in your equipment during long storage periods. MotoMix® is also made of non-aromatic fuel and fully synthetic, highly biodegradable engine oil. It’s no surprise that MotoMix® is the official fuel of the Stihl Timbersports Series

Motomix works in all Stihl engines and any other 2-cycle engine that requires a 50:1 mixture.

Stihl recommends that you keep fresh fuel in your equipment, and your fuel container. Do not let your fuel in the engine or fuel can sit more than thirty days, as the ethanol will evaporate and reduce the fuel efficiency. This degradation of the fuel will also allow the water that is trapped in the ethanol to settle to the bottom of the fuel tan and container. The stale fuel will also begin to form a varnish on the parts in the carburetor and fuel system, which will be partially dissolved by any new fuel added to the tank; which, in turn will clog fuel lines and the small jets in the carburetor.
