OK, here's my concern........... I fish a lot and have many friends who run 2 stroke and 4 stroke outboard motors on their boats. They have been warned of pump gasoline about to be sold with 15% ethanol and that it could do serious damage to their engines. It's supposed to be 10% at many stations currently. I ride an 06' KTM 300XCW with Chevron supreme mixed at 50:1 with Motul 800. I've used this brand and ratio since the bike was new with no problems. Runs great and clean. I don't know if Chevron will be going to 15% ethanol but if they and the other name brands do, is this something to worry about or am I making something out of nothing? Thoughts?
