Most people wrongly assume that if pump gas is good enough for their vehicle, it's good enough for their equipment. The truth is, using pump gas is the absolute worst thing you can use. Why is that? In a word, ethanol. Pump gas contains ethanol, which is an oxygenate additive. However, ethanol absorbs water. Secondly, water promotes corrosion, and that's not a good thing for the vital components of the hard-working 2-cycle engine that powers your outdoor equipment. Today's 2-cycle engines run hotter and demand better maintenance. Moreover, you can't store pump gas long-term because it degrades quickly and forms gums faster. That's why people have to put fuel stabilizers in their tanks when they store their outdoor power equipment.
