Well that E10 ethanol is a bit worrisome. In many cases there is no choice if you want to put gas in there at all. I have had some bad experiences of rubber parts not holding up, but kits are not that expensive. All the rubber fuel lines are new, I hope they last.
What is really scary is the proposal to increase the ethanol to 15%, but from what I have heard manufacturers are pushing back as they say that level is too destructive on the fuel system.
What I have noticed on my newer vehicles is a significant drop in mileage this winter. They purport that the winter mixture is for pollution. What I don't understand is if you get 25% less mileage, you use more fuel to cover the same distance, what is gained??
