Re: E85 can I do anything to improve fuel mileage?

I would not run E85 in any engine wether it is rated for it or not. You are getting a little over 16 MPG and saving only 50 cents a gallon? 1. Ethanol is very caustic to an engine. 2. there is a lot less energy in a gallon of ethanol vs a gallon of gasoline. 3. You would probably get 5 to 6 more miles per gallon with gasoline and I bet if you did the math it would almost be a wash. Aside from the fact that the ethanol is eating up the innerds of your engine much faster than gasoline would... Look for non ethanol regular unleaded gasoline and see what your MPG goes to then. I bet you will be shocked by the emprovement.

Re: E85 can I do anything to improve fuel mileage?

The fact is that you will be spending more money using E85 vs normal gas. Why people want/like e85 is pass me.

Re: E85 can I do anything to improve fuel mileage?

only time i would even consider e85 is if it was $2/gal cheaper than pump gas. other than that it's not worth it.

Re: E85 can I do anything to improve fuel mileage?

I'm going to leave the politics to the politicians here, but e85 has the potential to create more power in a tuned environment compared to standard gasoline. e85 has the properties of approximately 105 Octane, so if you want to compare prices then compare it to 105 which is about $8/gal out here.

Since Ethanol is Alcohol based it has natural cleaning and cooling capacities, the same reason drag cars use alcohol or meth injection. Even NOS injection - creates more oxygen in the system and has natural cooling properties.

Since the fuel is 105 octane it has less chance of predetonation meaning you can run a more advanced timing map given the same fuel.

So we're not saying that e85 will give you advantages by just putting it into your vehicle. But if you have the ability (currently we do not) to boost or tune your vehicle, e85 becomes the obvious choice. Most basic tunes for our motor require the use of 91 octane so already the price differential becomes significant for e85. Once you boost or run highly aggressive timing maps you'll need higher octanes and thus e85 is the only choice unless you enjoy paying $8/gallon.

So yes, for a stock vehicle I wouldn't vote for e85 unless the price is more than 25% cheaper. But once you start tuning, e85 is obvious.

LOL, the money isn't going into the pockets of American farmers.
It's going into the pockets of the ethanol producers and the congress-critters they bought off to give them subsidies.

Mandated ethanol in fuel is a joke.

When the 10% mandate was first introduced it ruined a LOT of fuel injected cars. The injectors simply could not handle the corrosion introduced by the ethanol.

Now it simply reduces gas mileage for everyone. The minutely smaller amount of pollution out the tailpipe is offset by needing to use more fuel in general to drive the same distance.

Don't even get me started on how bad it is for the marine recreational industry (yes I'm a boat owner and I'm glad my marina only sells non-ethanol fuel).

I'm an American farmer and money goes into my pocket when I sell corn that will be used for ethanol.

Boom

Re: E85 can I do anything to improve fuel mileage?

That statement tells me a lot, and I'm not buyin it. Ethanol is a wonderful misplaced product touted by misguided partially educated lobbyists and liars. All math and fact tells of it's actual heavy costs. From production to use, and it's loosing subsidy so it'll become clearer. It has its place, and will become more functional in the automotive world, but where it is and why it's there, it's a huge farce and a detriment. I told my buddy to stop talking crap and take a few engines apart, after seeing inside a crusty one he was blown away at how much more and less valid opinions became. I love e85 my jeep smells like pool chemicals when I run it.

Ethanol is a drug, a solvent, even an antiseptic. Stupidity is the poison. :-) Both kill one takes others down with it.

So when there was a drought 2 years ago and the corn prices were high and some ethanol plants went bankrupt, where was the subsidy then?

Now that there is Enogen corn it takes the production costs way down for producing ethanol.

It is possible you won't get great mileage with e85, but it is very likely you will pay less for it. Its a give and take.
