I'm not sure how many engines can't run ethanol. The worst I've heard is some fuel lines and pumps would corrode or fail sooner, but never heard or read anything like that happening specifically due to ethanol. I believe it can since there's ethanol-specific fuel pump upgrades.
What I'm looking at is the boost in tuning potential. E30 makes a huge difference over 91-93 pump gas so E25 should be similar. I was able to run 5 more pounds of boost in my WRX with 5 gallons of E85 mixed in with 91 with absolutely no issues over 3 years/40K miles.. With a 16.9 gallon tank, that's about 33-34%.
If all cars had to run it, I would imagine fuel systems would have a little more overhead to compensate for the lower volume of ethanol. We'd get bigger factory injectors, and possibly pumps. Also, if the engine were the issue, maybe we'd get better pistons and valves.
Thoughts?
