On boosted motors do they add in boost? I know the tuner guys have done it, seen one where they took a Eco tech F150 and got it into the 11-12's something crazy like that. Not sure how long it would last at that boost level but fun never the less.

This.

Just about any car that uses an oxygen sensor will be able to run e15. The sensor will adjust accordingly.

Every now and then I put some e85 in all my cars that are not e85 rated. E85 is a super detergent. In my testing, I have been able to run up to e30 without any issues. Any more than that and the 02 sensor can not adjust enough. That is because there are limits programmed in the ecu for 02 +/- adjustment.

Around my house, e85 comes out between 87 and 93 price wise. I run it because it is race fuel for the cost of premium. Mileage definitely suffers. Every more and than I will put a full tank in my Tahoe (e85 rated). The engine is rated at a higher hp in the owners manual running it. IMO the engine runs better/ smother on it. That goes for my street turbo car as well. If I have 93 in the tank and fill it with e85 while running, you can actually hear the engine run smoother.

I think they just adjust the timing table.

I plan on running 25-30lbs in my 9:1 old school sbf on pump e85, if i have the nerve to go that high lol. Hopefully 13-1400hp. Not bad on 2.69 a gallon, that last I looked.

That is incorrect information.

Probably...but it doesnt realy matter to me....the ethanol fuels i stay away from. I have tried them in my truck before and i do notice a nicer responce from the engine....but the fuel economy sucks!
Around my house regular gas as of this morning when i filled up was $4.54/gal
E85 at that same station was $4.15/gal
So at my 26 gal that i filled up on, it was $118.04 and it would have been $107.90 for E85
I get on average around 13mpg on reg gas
when i have run the E86 im down to 10mpg
so if i was to run my truck all the down on those 26 gallons i would be getting 338miles to a tank on reg gas but only 260 on the E85
So im loosing 78 miles just to save $10.14?
Even if i had extra fuel jug in the truck and used up that $10.14 differance and got an extra 2.4gal of E85 I could only go another 24 miles....still 53 miles short from using reg gas....
So where exactly is the benefit of this stuff? I can understand for racing purposes due to the higher octane of the E85 but daily driving i just dont see the benefit of it...

My concern as well. My 502MPI VST generation engines are very vapor lock prone with E10. I avoid it at all costs. No way I would run E15.

For performance, it's a no brainer imo.

I can't speak about the pro/cons for the environment. I've read it both ways.

For a daily driver, it comes down to how much a mpg would cost compared to what ever octane you need to run. Depending on the cost, the e85 could be lower, the same, or more per mile.

If it was the same or lower cost, I would run e85 all the time. Pistons and heads stay cleaner. Exhaust temp is lower as well.

One downside is you have full up more, less miles per tank.

Also depending on ethanol percent blend, which is usually 70-85%, the mpg will change. You will get slightly better mpg with the lower % blend.

New research out of University of Wisconsin - Madison, suggests that "the carbon intensity of corn ethanol is no less than gasoline and likely at least 24% higher."

I’m more worried how this is gonna affect the price of a bag of Fritos? More corn in gas, less for Frito Lay. :party-smiley-004:

Had gas boats for years however I've had a diesel for the last couple years and most of the places I frequent have one diesel tank....and one gasoline tank. The majority of them have E10 in 89 octane. The ones that do have E0 or 93 octane make a big deal about it since it's rare.

My concern is that these marinas are getting gas from the same sources as the road stations........and if E15 is the only option, that is what they are going to put in marina storage tanks.
