Night Fury Posted April 12, 2008 Report Share Posted April 12, 2008 The gas station I go to has regular 89, then 10% ethanol blended with 90 at the same price, and premium. Quote Link to comment Share on other sites More sharing options...
ismellrealbad Posted April 12, 2008 Report Share Posted April 12, 2008 If all the acetone does is increase octane rating, then there shouldnt be any benefit, because... Isn't a higher octane rating only helpful on higher compression engines to prevent predetonation? I'd imagine it would be detrimental to performance if you put it in an engine that's supposed to run 87 octane... Thats's true, but using higher octane on something that doesnt need it wont hurt, but wont benefit either. Its just simply a waste of $. Don't go putting race fuel in though Should say LACED with ethanol <sigh> agreed Quote Link to comment Share on other sites More sharing options...
Brian P Posted April 12, 2008 Report Share Posted April 12, 2008 Acetone doesn't raise the octane much at all, we're talking maybe a few decimals. I think its "equivalent" of 110 octane. Quote Link to comment Share on other sites More sharing options...
olds cutlass Posted April 13, 2008 Report Share Posted April 13, 2008 I gritted my teeth and bought a K&N air filter last week. Cant tell if there is a HP increase like they say although I try to take it easy now that gas is so high, but I did notice one thing, I got 433 miles out of a tank of gas. 420 miles is the most I ever got before.

Good job getting that filter. They're definitely worth it and pay for themselves and then some over the life of your vehicle. Quote Link to comment Share on other sites More sharing options...
ZoomZoomFan Posted April 14, 2008 Report Share Posted April 14, 2008 Around here, Wal-Mart's gas station is the only one that blatantly has 10% ethanol gas. And the GA always drinks more after a fill-up there. Quote Link to comment Share on other sites More sharing options...
AWeb80 Posted April 14, 2008 Report Share Posted April 14, 2008 our premium around here is clean of ethanol....and so is 87....just 89 oct. is 10% ethanol. I calculated one time (don't remember how I did it) that if you get more than 22-24 mpg using ethanol is cheaper even w/ the mileage loss.

I calculated one time (don't remember how I did it) that if you get more than 22-24 mpg using ethanol is cheaper even w/ the mileage loss. Now that you mention that, this brings up my next question.... Is it all the levels of fuel that contain this 10% or just 87 or regular? I said fuck it last time I filled up, and put 89 in the car ( we have 3 octanes here 87, 89, 93 ) and it seems like the car is running ALOT better. ( either from the gas or the computer has just really learned everything ) So is it just regular, or does everything contain 10%? Quote Link to comment Share on other sites More sharing options...

Regal_GS_1989 Posted April 29, 2008 Report Share Posted April 29, 2008 It may be hit or miss here. The signs at the pump say that it can contain up to a certain amount. Regular 87 may contain up to 10% ethanol, mid grade may contain up to 5%, and premium contains no ethanol. Quote Link to comment Share on other sites More sharing options...
Fleeingpepper Posted April 30, 2008 Report Share Posted April 30, 2008 Son of a gun! I found out QT (THE gas station here) started ethanol in the second half of last year. But apparently we have an odd summer blend here that contains no ethanol! And I read that ethanol 10% mixes decline by 2% mathematically speaking in a best case scenario.
