How did you know ?

If it is ethanol free, it would be because they mixed in so much other shit into the gas they cant legally get away with it. I know here in Boston, I can't find a gas station that doesnt have ethanol. Ethanol contains about 30% less energy by volume than gasoline and it absorbs water. That means we get worse gas mileage and worse performance. It also absorbs water, but theres no water in our gas :uhh:.

Shell and most other companies use ethanol. If your local gas station does not, feel lucky.

Federal law states all stations using ethanol must mark their pumps as such.

Also I asked the gas man about 5 weeks ago.

Their are 3 stations in a 2 miles radius that's ethanol free. Also there is no emissions testing or inspections in my area. So no cat for me.

You gotta ask yourself do you fill lucky?
I sure do!

Well then obviously you are not like 99% of the members on the forum. No emission testing or inspections? What does your city grow pot and make crack so laws dont mean anything lol. Good for you, I can only dream.

Out 0f the 7 Shells I went to, all 7 had ethanol stickers on the pumps. Gotta love that 10% that your getting. We should sell everything with a performance robber or something that degrades the original product. Atleast we would make more money. Oil now with 10% peanut oil, Kool Aid with 10% tomato juice, Women with 10% herpes.

Actually marijuana and meth is our 2 major exports. Look up north georgia and SE tennesee sometime you'll be amazed.

I knew there had to be a reason. Ethanol is bad for the meth :)

I topped off and went around 5 miles and I saw my gauge go down to 3/4 tank (8 gauges lie allot) so I filled it back up with Mobil and it took .8 gallons.. I might have hit red line a few times but still that's a bit much.. I was in a rush so maybe I didn't top off all the way at the shell station, that could explain the issue..

...Yea that was most likely it.

Maybe I'll give it another try.

I have seen pump prematurly stop pumping. It happened to me once. I was filling up from about 1/4 a tank and I put in less than $7 of gas and it stopped. I know I wasnt full, so I squeezed the handle again and it stopped after another $2 or so. Got in the car turned it on and I was close to being full but not quite there. Drove a little bit, when back to the gas station and put in another $3. Shit happens. To really get a good gauge of MPG and performance from gas, you really need to fill up with the same gas a few times. I have noticed a decrease in mpg for me. Probablly since I get all the Nitrogen crap and Ethanol were I live. I'll stick to Hess and Mobile were I seem to get better mileage. Im going to try Sunoco eventually, but its ever open when I need a fill up.

yea its happened to me before oh well.. I think I am partial to mobil becuase I get 1% cash back on my check card..

I like Shell because there's a 5% discount with their credit card. Hess used to be 5% but now it's 3%.

I don't think the shut-off pressure sensors on gas pumps are a consistent way to measure anything. It's very hard to fill up the 8's tank completely and I suspect that's on purpose because over filling is supposedly bad for the charcoal filter thingy.

yea I don't like credit cards though I get 1% back from my bank..

I haven't read any of the other posts in this thread yet. I use Shell Premium gas only. The engine is running fine, I've been using their nitrogen gas or w/e since it came out. I'm going to read the rest of this thread later...

lol. Cliff notes. Mazda does not recommend it. Shell has no comment. Some of us experience decrease in MPG while others claim an increase. I believe your MPG may have to do with where you live since some Shell stations do not have Ethanol while most do. Thats pretty much it.

I say we continue beating the subject to death...

we should start filling up on race fuel and premix for a month or two... That would be fun.

I would love to fill up with pur gasoline. No additives or extra enriching bs. We all know that will never happen though

i want to use jet fuel and have a turbine powered 8..

OK, read the thread, and I have to say, now that I think about it, my MPG has been lower lately. I attributed it to it getting nicer out and me using a heavier foot. But it might be the gas. I'm catless and get about 220 now whereas I was getting like 235 or so. I think I'm gonna try running a couple tanks of sunoco and see what the difference is.

Shell 93 is always 100% gasoline without ethanol, and with additives. That is why I used it all this time. My mileage dropped quite a bit with my first tank of 93 w/nitrogen. So I guess there could be an issue. So I am probably going to go 93 w/ethenol at some other gas station. If your car has a 100k power train warranty and only has 20k miles on it like mine, I wont bother with the little difference between 93 w/ethanol or without ethenol...just my $0.02

Come to Boston and you will learn how wrong you are. If you can find an Ethanol free gas station in Boston, I will find you manbearpig.

heh, all my co-workers are wondering why i just laughed so loud.. manbearpig

ITS HALF MAN, HALF BEAR AND HALF PIG!!!!!!!! IT ROAMS THE EARTH ATTACKING HUMANS FOR NO REASON!! PEOPLE WILL TAKE ME SERIAL

Manbearpig?!

:rofl:^ half man half bear half pig!

Depends on where you live. Some states has a regulation to have 10% ethanol. So in my area, I haven't found Shell 93 that doesn't contain ethanol - all pumps have the obnoxious "Contains Up To 10% Ethanol" stickers.
