After Bush's State of the Union addres this month, wherein he called for the use of E85 (85% Ethanol) to reduce our dependence on foriegn oil, I emailed Nissan N.A. asking about using E85 as fuel for our engines. Specifically, I was asking about whether or not parts of the engine/fuel system would need modification apart from the ECU. There are companies out there who make tuning boxes for many automotive makes/models, i.e. the Brazillian company, Flextune: www.flextune.com

These boxes manipulate the fuel injection systems of non-flex-fuel vehicles to account for the specific properties of Ethanol, producing a clean and efficient burn on every stroke. For those of you who are wondering if I'm smoking crack, see: http://www.ethanol.org/talkingpoints.html for more information on ethanol and what it means for the future of US transportation.

At any rate, I'm sure at least a few of you have been wondering about our Frontiers, and without further ado, here is the response I got from Nissan:

"...the Frontier cannot run on E85 (Ethanol) fuel at all at this time. Only the 2005 Titan FFV can consume this type of fuel. There were special fuel tanks, pumps, and hoses that were installed at the time of manufacturing, that can withstand this more corrosive fuel for the 2005 Titan FFV. Modifications cannot be made to the vehicle to accommodate an alternative fuel, due to the vehicles internal parts being designed specifically for the vehicle and installed at the time of manufacturing. At this time Nissan North America, Inc. has not released any official information regarding a tuning box for these motors, or if or when Nissan will produce a 4-cylinder diesel version of the Frontier."

The good news is that it appears as though it's only going to take a new fuel pump, tank, and fuel lines to be flex-fuel ready. Then, it's just a matter of finding a tuner to remap the ECU. I don't know how expensive the fuel pump will be, bu the tank and lines shouldn't be prohibitive at all.

If you've found a source for Ethanol ECU remapping, or for the parts mentioned above, please post it here. After running biodiesel for years in my Golf without issue, I'm ready to kiss another warranty goodbye in the name of reducing foriegn oil dependency.

I don't understand why they would need to replace the fuel tank, isn't it already plastic? My Explorer was FFV and it had a plastic fuel tank! Of course gas mileage sucked using E85, and you could feel the difference in power as well! I never actually sat down and figured out if it was more econimical to run E85 based on the higher fuel consumption, because the only E85 station was by no means convienent to where I live! If they could figure a way to increase the mileage a bit using E85, and the fuel was more widely available, I would be interested in a conversion! As it stands now, it wouldn't be worth the cost and inconvienence!

It was $2.02 here on Monday, and last night it had jumped to $2.25! From what I've read recently the price of crude dropped, so I don't know what is going on (other than gouging!).

Right now in Denver the cheapest I saw was $2.06 for 85 octane (not E85) at a Costco. I use 87 octane which is anywhere from $2.16 to $2.35 depending on where you're at. But I'm sure glad I don't live in California, my brother lives in Northern Cali and says gas prices flirt with $3 a gallon all the time!!

As for the Ethanol 85, I'm not really suprised that Nissan isn't really on the bandwagon yet. It seems that only the American manufacturers are really pushing it, especially GM.

So can you run regular fuel when you tune the motor for E85 or is it one or the other?

Sorry, the sign was a stock photo from google images. It doesn't represent the price of fuel here in Phoenix..where, like everywhere else, we're getting gouged too. Please keep this thread about E85 so it doesn't get too convoluted.

Thanks,

I filled up for 2.19 at Chevron last night, then saw another Chevron on the other side of town for 2.05... jerks. Lowest price in town is probably Arco at 1.95 but I'd rather put Jack Daniels in my tank.

Not yet. Biodiesel is available from Western States Petroluem near downtown Phoenix, but no one has opened an E85 pump up here yet. I suspect that will be changing soon though.

Yeah Nothing in Phoenix, or Tempe, I've been looking for it. Not that it matters anyway, we cant run it. Its interesting, because I think pretty much all the Titans/Armadas are FFV. I know our Armada was, and we didnt add any extra options to run E85...it just came that way.

The Ford Flex Fuel Vehicles like the Ranger and Explorer can run both. I would think a conversion would be able to as well.

Has anything changed with this. E85 is 1.00 cheaper then gas around here. So looking to see if I can use it.

no. basically, E85 destroys certain parts like o-rings and seals that it comes in contact with unless they are made to handle it. I think there's a whole lot more you'd have to change out to run E85.

not only that, you get 2/3 the mileage with E85 that you do with regular gas. a buck less a gallon is still 75% of the cost of regular so in the end, it will cost you more.


...Troy, NY....almost spent 4 years there...

I had to look back at the dates when I first saw this post to find out how their price was half of mine. What a difference a little time can make.
