The only vehicles that should run E15 are those that are already flex-fuel certified (ie can run E85), anyone running E15 in a non-flex system is in for a world of hurt with very expensive repair bill coming most likely.
Where did that info come from. Toyo says to not run greater than E 15 in my highlander. :h
Maybe things have changed since I last looked into it then, at the time most vehicles were either made for E10 or E85 and those made for E10 generally had a bad time when run on anything more.
*Edit*
Ok, so after looking into it a bit it appears that more manufacturers and models support E15 than when I last looked, but even the Renewable Fuels association says that less than half the vehicles on the road carry a manufacturer support for E15. I guess the new answer I should give is if it's not flex-fuel then check your owners manual.
