Having been around E85 cars for a while, and our experiences, we have never used special oils or done anything different from a regular gas powered vehicle. I have yet to see an engine failure due to just making the switch to E85. Just make sure you have enough fuel volume and that you're tuner knows what he's doing.
Using diesel oils is a good idea for performance cars anyways as they carry more zinc and lubricants.
Yes your right , but my idea here is trying to determine how a motor longevity will be if it is daily driven on E85 ..where lubrication can play a big role during the usual 3k mile oil change interval ..I'm sure a lot of guys using e85 in here aren't daily driven cars so using it at the track on a Wednesday night or a dyno sesh with fresh oil wouldn't be an issue ..I'm trying to find out if is true I got to change the oil evry 1500 miles if car is daily driven on flex fuel and not wait til it has 3k miles ..also what would be the best oil due to the fact of e85 thinning the oil
