Gasoline Guidelines Gasoline storage life: You may not realize it, but gasoline begins to decompose and break down into other compounds in as little as one month when stored. With the ethanol separated from the gasoline, the layer of gasoline now has a lower octane level than the original ethanol gasoline blend. Guidelines for using E10 gasoline in STIHL power equipment: U.S. EPA regulations make it illegal to use gasoline containing higher than 10% ethanol content in outdoor power equipment like your STIHL power equipment and doing so can void your STIHL Limited Warranty.

Only mix enough fuel to last you one to three days at a time; this limit keeps the fuel fresh and minimizes the risk of any buildup. If you find mixing to be too time-consuming or annoying, Stihl does offer customers other options to run their chainsaws, such as Stihl MotoMix, a pre-mixed, high-performance fuel that is ready to use straight away, eliminating the need for measuring, shaking and storing. Whether you purchase a pre-mixed fuel or mix your own, following the correct ratio can keep your chainsaw working properly and keep it working for years.
The focus of the presentation is not to make you a chemist, but rather to explain in simple detail what is in fuels, how to properly handle and store fuel, and to give you an understanding of the new fuels of today. Higher octane fuel may contain other additives that may enhance the fuels’ stability, and fuel system cleanliness, particularly in automobiles. Winter fuel will vaporize at approximately 34°C and summer fuel will vaporize at approximately 45°C. Therefore, on a warm day of 28°C and some added heat from the running engine, winter fuel may become active or percolate in the fuel tank and could vapour lock in the fuel lines or carburetor.
