The feds will be diluting 10% ethanol to 15%, which some auto manufacturers say you shouldn’t use, but…

…today I checked the pump when I got some of what I usually get, which I’m sure is E10 (and 87 octane) and NOWHERE did it say E10 or anything about ethanol content anywhere on the pump.

How the hell are we going to tell which one to avoid when the E15 comes out?! (I know they are saying E15 that it’s okay for cars 2001 and newer, but I’d rather go by what the manual says, especially when it says damage can result.)

EDIT: Attaching one of the articles I read (there are more).
