Have to agree with Patracy. Ethanol in a diesel is a pathway for water, and it will wreck ALL your rubber seals and hoses along the way. I was a small engine technician for 2 years. Best thing that ever happened to that business was ethanol in the fuel. It destroys the diaphrams in small carbs and all the o-rings in bigger carbs. And that's with only 10% ethanol up here. I recommend you run premium fuel in your chainsaws and stuff, since at least in Canada, they're not allowed to put ethanol in it (yet). I like ethanol in theory. But EVERYTHING rubber on an engine/vehicle/fuel-system needs to be replaced with fancy (expensive) special alcohol resistant rubbers for it to work.
