10% ethanol in diesel?
Well here over the past two weeks or so i've noticed a drop in fuel economy, and the dpf filling up and going into regen a lot more often. I have no cel, fuel and oil filter have been changed recently, and I can't figure out what caused it. When I went up to the same station I usually do to get diesel, I noticed fresh new stickers on the diesel pumps sayin that it may contain up to 10% ethanol. First off, I thought that was really bad for diesel or something? Also, I have a feeling that this is the source of my drop in fuel economy. Any thoughts?
