I use E-10 fuels and Mercury Quickare and Quickleen with every fill-up... Recently had the lower crankcase seal go bad. My mechanic said i had one of the cleanest engines he'd seen in a while... Only time I idle is to get the engine up to operating temp and the cool down after a long hard run... Dan
