Anyone know anything about this?? I saw it on the news last night. It's called E85 fuel. It can be run in some factory cars. I was wondering why it cant be run in all car's. Would it mess with the cat's or injectors, maybe it's timing??? It's about 50 cent's cheeper than gas, that's why I'm wondering. It would be great to run in older carb. motors (if you can) or in older trucks that use a ton of gas. That would be one hell of a savings on fuel. Shocked

If anyone know any reasons why it can be run in older trucks? Or new cars. I know that it's high octane it's 85% ethanol & 15% unleaded gas. It should make Mother Earth happy. It burns clean. Laughing

Well I thought I would bring up the subject.

If you have a Flex-Fuel Vehicle, then you don't really need to "switch"... just go buy E-85 and try it. If you don't like it, quit buying E-85.

I think that whether it decreases MPG or not depends on your driving. Modern engines have a "knock sensor", and they detect when the engine is pinging under load. This happens when you're pulling a loaded trailer, or even when you're climbing a hill, but haven't bothered to downshift yet. When the knock sensor senses preignition, it backs-off the spark timing, which can reduce gas mileage.

E-85 has an octane rating over 100, so you can think of it as "very super premium" fuel. It should be practically impossible to get preignition/pinging while burning E-85. This means that the spark doesn't need to adjust, and gas mileage may actually go up with E-85. Laughing

Even if you find that mileage goes down a bit, E-85 is cheaper than gasoline, so it mostly balances-out.

Now, if you are thinking of converting an old (non-FFV) engine to burn E-85, then gas mileage will go down, unless you modify the engine a bit (such as increase timing & jet's in the carb.). that will give you more power. That's what I found out so far. Shocked

It would be interesting to find out it there is an alternative fuel tax credit available for using this stuff.

Joe had done some more research on this yesterday. Looks like older Carbureted vehicles need to be jetted differently so that the engine doesn't run too lean.
