FI and Ethanol Blend?

DIGItonium · 06-19-2010, 12:15 AM

No problem. I guess I should be more worried about the corrosive nature of running E85 on a stock 370Z, correct? I didn't know it had higher octane properties. So can it serve as a mild octane booster? :-P

If you add it in your tank it can actually have an adverse effect on your octane rating.
Corrosive.... do some reading up, some good testing has been done on 'nonE' motors and no wear signature was found, in fact some cases it was actually better..there are off course arguments for both sides as expected, I think the main concern is when the fuel is left stagnent, i.e. long term parked vehicle, also some seals , O rings etc could degrade if not sepcifically designed for E.
Personally I have converted 3 vehicles to E85 and all I changed was the fuel pump, injectors on two of them, the other had new fuel rails, new injectors, and an FPR, never had an issue, granted my tank never stayed full for long ;-)

I know plenty of guys running E today on non E vehicles, hell my pal down the road ran his 454 69 SS Camero on it lol no ****, guy one up from him has a blown viper at 700 WHP on it, designed for it? no, tuned for it, hell yeah

Finished up an 'E' tune on an 08 STi yesterday, 22 psi, 20 degs of timing through midrange and 11:8.1 fuel at WOT, thing was quick....

I'm looking into switching to E-85 now. Trying to get a quote on installing a fuel cell/fuel system and bigger injectors. So far the companies I emailed have not replied.. Might have to hit up AMS.

Is 93 bad?
That's all I've been putting in my z.

Kastley85891 · 05-08-2011, 06:03 AM

93 is great, especially when you had 2 years on 91 lol

I live in Virginia and all the pumps are 10% ethanol. I follow Pat Goss's (automotive guru, MotorWeek TV, Goss's Garage radio show) suggestion of adding some Stabil to my tank every couple of fill ups.

This has the added benefit of removing any water that may have formed in your gas tank.

Stabil now makes a dedicated ethanol treatment as well.

I don't know much about this stuff. Stage II on the way, and I don't want it to mess anything up even for daily driving:

Wow thanks alot dude i've always heard that E85 was good for boosted cars but i never worked the kinks.

I guess it's fine as long as it is tuned to support it. It looks like he has to dump more fuel to reduce the likelihood of running into a lean condition. Eh... this stuff is way over my head.

IIRC, ethanol warning signs are removed some gas stations so it's a hit or miss. That's pretty scary, but it would be nice to see some official testing and results other than stuff I've found here:

Ethanol Producer Magazine | EthanolProducer.com
The Independent > Archives > Opinions > Letters > Don?t remove ethanol labels at pump

I don't know how reliable the site below is, but it mentions some of the symptoms people described like water in the tank (possibly leading to leaner condition?)
