AREAS TO AVOID IN CROSS COUNTRY MPG TRIPS
courtesy of ExxonMobil

ETHANOL IS FORCED ON CONSUMERS OF SEVERAL STATES AND METRO AREAS, REDUCING MPG BY ABOUT 30%. ALL OXYGENATED GASOLINE CONTAINS ETHANOL. FUEL UP OUTSIDE THESE AREAS FOR DRAMATIC MPG GAINS! I DO - AND I GUARANTEE THAT IT WILL MAKE A HUGE DIFFERENCE.

IF YOU REALLY LOVE ETHANOL, YOU CAN MODIFY YOUR ENGINE WITH HIGHER COMPRESSION AND DIFFERENT TIMING TO RUN ON ETHANOL-RICH GASOLINE OR PURE ETHANOL FOR AROUND $2000 TO $5000. BUT IN CONVENTIONAL GASOLINE ENGINES, INCLUDING "FLEX FUEL" TYPES, ETHANOL SERVES A PRIMARY PURPOSE AS AN OXYGENATOR AND A SECONDARY PURPOSE AS A LOWER QUALITY FUEL. THIS ROBS MILEAGE AND THROWS AWAY ANY SO-CALLED "GAINS" FROM AGRICULTURAL FUELS. IF YOU HAVE ANY DOUBTS ABOUT THIS, SIMPLY MAINTAIN A MILEAGE LOG ON YOUR NEXT CROSS COUNTRY TRIP - USING THE ABOVE MAPS. THE DIFFERENCE IN MPG WILL BE LIKE A SLAP IN THE FACE.

THE ETHANOL MANDATE IS A PAYOFF TO THE FARM STATES BY POLITICIANS. AND NOTE THAT MOST OF THE FARM STATE AREAS DO NOT HAVE ETHANOL MANDATES.

I ASKED A FARMER WHY THEY DON'T RUN THE ETHANOL THEY MAKE IN THEIR OWN FARM EQUIPMENT. "WE'RE NOT STUPID," HE TOLD ME. "WE CAN'T GET ANY POWER OUT OF IT!"

Pardon my french, but don't be stupid. :mad:

Edit: I found the link.

So Exxon/Mobil is recommending to not use ethanol?

I tried a 10% blend with ethanol and a non-ethanol.

There was no difference in mileage.

This was with the same fuel table and ignition table.

Pure ethanol (e100) has 76,100 BTU/gal.
Gasoline has 114,500 BTU/gal.
You're saying mixing has no effect.
Really?
Perhaps you need to pay closer attention.

but noone (that i know of) mandates more than e10, so youre looking at 3% reduction in btu, not 30%

i do seem to get slightly better mileage when i've ran straight gas vs. e10 (i've only ran like 5tanks of it) but, where i live, e10 is cheaper. i get better miles per dollar with it. i run e10 unless straight gas costs less than 3% more, which almost never happens here.

This has already been hashed out about 1000 times.

Perhaps you need to pay closer attention. :rolleyes:

Using E10 does slightly decrease MPG, but it's just not feasible for it to be anywhere near 30%. Even if the ethanol didn't contribute at all, it would just be a 10% reduction...but the ethanol DOES contribute.

I here what your saying. I only tested the two fuels back to back one time. So it was not enough data to truly come to a scientific conclusion.

But trust me I'm very careful when refilling to get the same amount per tank.
(I use the same level spot at the same fuel-station, I check the fuel level with a measuring rod, I take notes on the ambient temperatures to account for the coefficient of volume expansion for gasoline being 950x10-6, I test the alcohol % of the fuel)etc.

I thought for sure I would see somewhat a gain when running the
non-ethanol fuel. But after seeing none I decided it wasn't worth it at this point and time in tuning my car for maximum FE. So now I have been doing all my test with the 10% blend.

Couldn't see either link.

Also wtf are you talking about? 30%...
