I guess CA only have E85(85% ethanol) and yes not 10% ethanol Whatever you call it.nelson8708 wrote:they dont call it e10. Most pumps in indiana are e10. There is usually a little sticker some where on the pump that says could contain up to 10% ethonal. Its not a law in indiana that all gas has to have 10% ethonal in it though. Your tune will be fine. Its not going to be a noticable change.
