Please keep politics out of this, it's not meant to be that kind of question.

I know it's been on the news that they are going to bump gas from E10 to E15 to help reduce prices at the pump. Is it ok to run E15 in cars? I see some stations around here are 10% ethanol and that's usually what we use. I am not sure of some other stations because I never really paid attention to what percentage of ethanol it is. We have a 2008 Dodge Avenger with the 2.4L and 2014 Dodge Durango with the 3.6L engine. Would going from E10 to E15 do any harm? I do not think the Durango is flex fuel and I know the Avenger is not. If they were flex fuel, I wouldn't worry about it. I looked at the owners manuals for both and did not see a certain percentage limit listed.

The Avenger has lifetime factory drivetrain warranty and the Durango has lifetime max care. Don't want to void a warranty because I can't find E10 and have to use E15.
