Costco Gas

[Newman]

Chevron goes in mine unless I have to go to shell or texaco ...

I usually get shell since it's down the street from me but next time I get gas I'll try a tank of chevron and see if I feel a difference

 

[Mr. Q]

does anyone have any concrete evidence that fuel rated at 91/93 octane at one gas station is better or worse than the other?
so far, a bunch of people who claim "butt dyno" and an incident at the track blaming on fuel.
i thought this forum was better than "butt dyno" and a single incident at a track and jumping to conclusions stating arco gas is shit, etc.
why, then, does ford promote bp fuels? bp fuels is arco, btw.
i've never seen any difference between different fuel stations, chevron, shell, 76, arco, even a pos gas station. so far as i can tell, my car only runs worse with lower octane fuel.
yeah, my car's not fi atm. but i've had fi cars before and put in all kinds of 91/93 octane, taking it to the track and running her full out. never had issues.

i'd like to see if anyone has any REAL evidence of fuel being "watered down". it would seem like a really big deal if gas companies were doing so, no? we're not the only ones filling up on 91/93 octane. so the guy in mercedes s550 pumping 91octane next to me at costco is likely to eff up his motor because he's filling it up at costco? c'mon man.

Out here over the hump, our Union 76 station used to sell racing gas. Then Rebel took it over and all we get is 91 octane, too. Since that's where most of the modded cars go for fuel, at least I know it's fairly fresh, hasn't been sitting in their tank for months.

Select Rebel stations here in town (mostly the ones that used to be Union 76) still offer 100 octane. But I sure as hell am not going to get tuned for 100 octane and suffer the $7/gallon. And it's pointless to put 100 octane in when tuned for 91. If I remember correctly, my dyno guy said putting in a higher octane than what you're tuned for won't yield any extra power, and may actually might bring power down. I've been filling up at a Texaco (chevron) station near my house. The car likes it, so I'm pretty happy with my fuel situation... for now...

I wish I had this car like 11 years ago, when 91 was just $1.09/gallon.

9 yrs ago.. I'd fill up my 01 GT @ 99c/gallon at local gas station in atlanta.. good time...

My mom loves Costco gas … because it cost less than anything else in Ft. Lauderdale. extra gallon just to get there though.

They probably get their gas at the same bulk plant as the Chevron's and Exxon's in your area, but they add their own "propriety blend" additive.

Original Poster...search gasoline...each city has tank farms. What you get all over town comes from two or maybe 3 sources--pretty much all the same.

true...ish... some additives effect a/f more than others; thus NOT the same. get a gallon of several, pull pump and stick in each gallon, do a run on dyno and watch a/f.
