Jeff, go Google "Volumetric Efficiency."

 

Dan, just explain you point

 

The OP was asking if we can run E85 in our cars and your simple answer was NO. When in actuality you can and it could be advantageous, but not worth the $$$ IMO.

Then you blurred out that in order to accommodate higher octane fuel in a car you need to build the motor which is wrong. The only fuel that you would have to change things for is E85 which I did point out. He would need a tune which consists of fuel and timing maps and thats because of lower energy content associated with E85.

I also said I can run C16 in my car without problems ........ I didnt say it would be advantageous without FI or higher compression....did I??

I think your definition for accommodate differs from mine and thats why you got your panties in a bunch.

Also in the engineering world compression ratio is not the same as compression pressure, but Ill save you the embarrassment.

And please save me the explanation of what C16 is since I have a drum in my garage for my other car.

 

You can't run E85 w/o extensively modifing you fuel system. Not that facts are really important here anymore.

Again wtf does C16 have to do with E85? I could say I could run ape **** in my car but that has nothing to do with convesation now does it?

At anytime you want to start making sense, let me know.

 

Me making sense. LOL!!!!!!!!!

I didnt say that in order to accommodate higher octane you need to build the motor. YOU DID!!! Thats why I said I can run C16 in a car without problems.

 

To take ADVANTAGE of the E85. Which includes what? Altering the fuel system.

Now listen closely. E85 and C16 are NOT the same things. What part of that statement is NOT clear to you?

 

Where did I say that E85 and C16 is the same thing.

 

When you said you run C16 w/o problems. I never said you wouldn't have problems running C16 now did I?

Look I can run whatever octane also "without" problems. The problem is you are wasting your effort WITHOUT building the engine with that octane in mind. Turbo cars can up the boost. NA cars need to up compression. Running advanced timing won't do much.

Lastly, you cannot overcome the lower energy content of E85 w/ timing mods.

 

too corrosive for our engines.... would **** them up.

 

Actually I think it's just the fuel lines that need to be taken care of.

 

Ethanol in E85 will oxidize and ruin your injectors.

I don't even know why they market these fuels that are supposed to be cheaper and environ mentally friendly when they take unsustainable amounts of corn to produce the alcohol and it ruins engine parts prematurely. It isn't even that much cheaper IMO.

Kind of a half ***** band aid for a huge problem.

 

There is a section in the owner's manual that specifically addresses E85 and states not to use, good enough of a reason for me

 

I know this is an old thread, but I thought I'd post my results here and bump in case anybody's interested.

I've been putting pure E-85 into my 2008 G35x without any problems yet. I'm in five tankfuls, so I can't speak for longevity.

As for power, and the car is bone-stock, I made some 1/4 mile runs today with an accelerometer, and was running a high 14 (we're in Denver, so remember altitude power losses for being at 5,200 feet). Based on car weight and this 1/4 mile time, I calculated roughly 260 WHP, definitely not "significantly decreased performance" like people seem to think.

I used pure E-85 in my old '96 Mercedes E320 for almost two years, and never had a damaged fuel line, injector, or anything.

 

I don't know if I'd take that chance. Especially since you're still under warranty, if a fuel-related component should fail down the line, I doubt they'd cover it since you used unapproved fuel. Have you checked your fuel economy to see if it's better or worse? Most MPG with E85 is worse than with regular fuel, so economically it really doesn't make sense to use E85. E85 is really to satisfy environmental peeps and those who want to take away a little from Big Oil's profits.
