Flex fuel conversion possible?

Not really, an answer but I had a Nissan Titan at the time when it sounded like E85 would be everywhere. It was easy to figure out on that as there were some Flex-fuel Titans sold. On the Titan the only difference was a few stickers and the alloy on the fuel injectors. I would speculate that a 4th gen T4R would similar.Mtneer001 said:

Flex Fuel
I suppose it is possible to do a Flex-Fuel conversion......but is it feasible? Using E85, which is less expensive than unleaded gasoline, may seem like the prudent thing to do; but bear in mind that E85 (85% ethanol - 15% gasoline) has less "energy" per gallon & fewer BTUs than gasoline alone.
If it costs 20 percent less, but gives 30 percent fewer miles per gallon, do you really save anything in the long run? Probably not.
Still, though, I am happy to see that there are more E85 stations popping up. Ethanol is not the solution to our energy woes, but certainly is part of the equation.
:awais:
P.S. GM and Ford both have "Flex Fuel" vehicles available now. Well, okay, I know that few people here would ever buy anything from Detroit; but maybe someone else might.

I have converted my Honda over to E85 only for the 105 octane benefits and the lower egt's with alc. Almost 200 degrees cooler I had to get way bigger injectors and then some engine management to control it. It does use about 30% more fuel than regular gasoline though. I want to do this to the runner, but the engine management is what is stopping me. Must be obd2 compliant, and you just can't find a tuneable obd2 ecus for the runners.

Well, best of luck to you! Such a conversion doesn't seem like it is worth the hassle, but I am not one to 'dis' anyone for being innovative or coming up with an alternative to the status quo.
Have a great day!

:iagree: not only is does ethanol have less energy than gasoline, IIRC, GMT900 with Flex Fuel engines cost more. Which brings back the question, like hybrids, how long will it take to break even compared a traditional gasoline version of the same car. But if more of us can be less dependent on fossil fuels, the price will eventually drop.
Flex Fuel vs 10% ethanol
I am curious on this. More and more stations around here will have stickers on their pumps, "this fuel contains up to 10% ethanol). I try to avoid these as this type of fuel does impact overall gas mileage.
How much ethanol is in E85? 85% or 15%.
I also wonder if using just 10% ethanol is harmful to an engine like the V6 Toyota which is not designed to use it.

Engines designed to run ethanol only actually can get really good fuel economy. E85 has a high octane so the compression can go way up, increasing economy. But unfortunately, then you can't use gas.

E85 indicates 85 percent ethanol and 15 percent gasoline. Likewise, M85 refers to 85 percent methanol and 15 percent gasoline.
Every gas station I've seen here in VA has a 10% ethanol blend (E10) to satisfy our oxygenated fuel requirements as per the EPA.
Any car on the road should run fine on "gasohol" blends of up to 10 percent alcohol and 90 percent gasoline. I don't even know of any stations anywhere that still have "real" gasoline.
