I think you can run E30 to E40 in about anything. I stubbornly (even though it probably pays very little per hour) put about a third of a tank of E85 in when I fill non-flex fuel vehicles and then top it off with whatever they call their 15% ethanol blend. Never have any issues.

Should clarify I don't have any turbo vehicles so I'd have to think about that a little before I went ahead with it but I think that would likely not change my perspective.
