> the sunoco at the circle in ea has 91. but, as stated earlier, 91 is literally 2 cents cheaper, so even if i pull in to the gas station running on fumes, i will spend 22 more cents for a full tank of gas so i just get 93.

:word:  
but i guess his car gets way better mpgs, and isnt so rich

hey kind of a same Q… are people still killing themselves to save 10 cents a gallon at the res? or they are starting to realize the 10 cent difference in terms of percentage difference isn’t worth?

what i mean… in case this drunken state is unclear…

1.00 a gallon normal (filling 10 gallon tanks) = $10  
.90 at res = $9

10% difference

3.00 a gallon normal = $30  
2.90 at res = $29

4% ish difference

also i haven’t been out the res in a while… what are the price differences between the two… about 10 cents?

apparently the dr. has heard that other people that own the same car as he does 😉 have been getting better gas mileage with 91 as opposed to 93. they will allegedly will run less rich with the lower octane gas and he wants to find out where he can buy it to see for himself

"octane too low = hot - detonation - engine compensates to shitty mode  
octane too high = cold - unburnt fuel - no compensation just wasted gas

see that’s the other side of the spectrum, which can be just as inefficient. Too much octane and your car has a hard time igniting the mixture, and will tend to leave more unburnt fuel, and resulting shitty performance, sluggish acceleration, bad MPG.

I remember when I ran 94 and I always had this hesitation every 500rpms or so under WOT acceleration. I ran it down to empty and tried a little experiment and bought 91. Problem never returned, then I looked into it and figured out what happened.

high-octane is all hype, they claim great mileage and performance, but it is only true if you can advance ignition timing and raise engine compression to take advantage of it.

You should always run the recommend octane, as the maps were designed for it, unless you have changed timing/compression to warrant it. "

I figure that I will give this a try
