E85 Ethanol Gas

[jurgs01]

I get 93 Octane at a Stinker gas station which is always 10% ethanol. My car runs better on that than anything else.

I did try to contact Mazda through a service manager friend here in KC for another guy's question (read here: Thread ). he tends to know what he's talking about and he told me that its a bad idea. I'm sure that you can do it, I'm just not so sure its a great idea long term...

I called a couple of local dealerships (detroit) and the service guys there said that running e85 will dry out the seals very quickly.

Dog knows we don't want dry seals... Walruses are OK, but not seals...

lol fun stuff

wow you guys are behind on this stuff, ive been injecting methenol into my motor for a few years now with great results. ran up to 14psi on the stock ECU and injectors without detonating and my motor is in great shape. Ive got few threads about the effects around somewhere. Using it in the fuel should not be too bad, i used 94 pmp gas thats about 10% ethenol, pour maybe a liter into the tank with maybe 6-7litres of fuel and inject it into the motor as well. Its called the easy way to run high boost and not blow a motor. There was an equation on the net I found once that said if im running 94 base gas(nothng added from me) and injecting methenol into the charge piping you work out to having the equivilant of over 103 octane. Not too shabby. Wesman also ran 14psi for quite a while on the stock motor, NO EMS of any kind, then his clutch died so he built the motor at the same time i think.

anyone here want to do the necessary mods to run strait e85? It's a small pipe dream I have, standalone and upgrade fuel system... can't be that hard, of course my carputer comes first.

Your mileage definitely decreases with ethanol blended gases because it does burn quicker.

Etanol has lower energy coefficient and you need a greater amount of it in order to provide the same energy coming from fossil fuels.
Therefore you need more ethanol than fuel to have the same energy output.

^^ ahh but Ethanol is a renewable resource vs fossil fuels which take a few million years to make.

also more money goes to famers and less to towel heads in the middle east (I don't have anything against them, its just the first descriptive word I could think of --eh, its the internet)... also the byproducts of making Ethanol make a real cheap pig feed...

we're not behind,we're trying to learn about running ethonal on a stock fuel system,and what the ECU reactions would be.




very aware of methonal injection,aswell as water injection.

if the car was not designed for E85, DO NOT RUN IT
you WILL corrode your fuel lines and seals and possibly ruin intake manifold gaskets

So hypathetically, if someone wanted to run E85 on a stock motor, stock ecu, stock internals, then they would need;
New fuel filter & lines- would they need a new fuel rail? how about injectores? are they plastic?

and they would have to get a new intake mani gasket, maybe copper? What other gaskets would need to be replaced?

I would think that if the ecu can do the calculations automatically, then the rest is just a matter of changing the items that would corrode. I have day dreams about this, but the actual details escape me.

one other issue is E-85 needs to be run at 9 to 1 A/F rather then 14.7 to 1

Some of the fastest N/A hondas in PR still use STOCK ecu with mechanical injectors to run alcohol.

Blending it with gasoline, yes, it gives potential to run more power, but I recomend a dyno and to monitor for knock if running stock...since it may lean out a bit the fuel mix.

What do you guys think of Toluene?

Have anyone try it and where did you guys purchase it from?

That's a big if. I don't think our ECU will adjust that much.
