Costco gas does not have to be the same brand of gas each time they get a delivery. The only Brand Name they have to "live up to" is Costco. I'm sure they buy spot market too.

...i heard 76 gas burns better for performance. .... most auto racing tracks (around here) use 76 gas... (the octane is in the 100's)
..... i use chevron,, i've heard it burns cleaner because they added techron... (kinda like heathy food for you car)
.... one time my wife put safeway gas (in vallejo) in her honda, and the car ran like sh*t, sounded like sh*t and wanted to die.

I always stick with the main 3 in the area, Mobil, Shell and BP-Amoco. I think Exxon is pretty good too, but we don't have those here.
Interesting reading about the toptier brands. Does MB recommend any specific gasoline brand?

Gasoline Question
I use Shell premium, however it contains 10 percent ethanol. I contacted MBUSA and asked if the 10 percent level would affect my injectors. They responded by saying no problem so long as the concentrationis less than 15 percent and /or the octane rating is 91 minimum. No problem burning the Shell gas in my car... ' 05 E500. I have been able to get 23mpg thus far, wonder what my mpg would be without the alcohol.

didnt mean to resurrect this thread, but I've been looking at chevron alternatives, and I noticed you mentioned that website as did a lot of other people, without investigating who actually owns it..
How can a bottling company know anything about fuel ? It is obviously a FAKE site.

I run 93 in our E320 as I don't have 91 available in the Atlanta area. It runs fine on BP, Costco,QT, Shell, Standard etc. I can say that I run 87 in my 3.5 liter Maxima and on occasion the Costco gas pings like crazy to the point that I have to dilute it with better gas. The Maxima has noticeably better power on premium but I rarely treat it. It "performs best on premium fuel"
As for the differences in gasoline. As far as I know, all of the gasoline in this area comes in a pipeline from Texas. It is stored in a tank farm in Doraville, GA. I have seen every flavor of fuel tanker come and go into that facility. Several name brand companies have their logo on individual tanks but I suspect that all of the gasoline that comes in the pipeline is refined as one. Any improvements claimed by individual brands would have to be an additive, not a refining technique.

Strangely, in my 2002 Caddy, performance and gas milage always went down whenever I used BJs or Costco gasolines. These gasolines also have weak detergency. ...and yes, supposedly the additive package it the last thing that gets dumped into the tanker truck... but one of the additives could also be an octane booster, which will cause your cars computer not to retard the timing, which will also give you more power.
Higher octane and higher detergency is whats best for our cars, but nowadays, for many, the cost of a fill-up mixes into the equation too.

I've always been a Chevron/Texaco man, running it in all of my cars....
But after Hurricane Katrina, I started running Racetrac and Quik Trip gas in my suburban and really didn't notice any MPG dropoff. But I still run Chevron/Texaco in my E500.
I went to Mississippi a couple weeks ago and filled up at my local Chevron and got 24.4 mpg for the 451 miles I drove. But on the return trip, I stopped at the only gas station I could find (a Racetrac) and got 26.8 MPG!!! I've never gotten over 26 on the highway... I've yet to duplicate that kinda performance but I'm interested in seeing if it was a fluke or not...
I'm going to run Racetrac (93) on my next 400+ mile jaunt, and see....

During our recent Christmas trip from New York to Denver and back, I noted through Ohio, Indiana and Illinois in both directions that my mileage dropped. Normally get 25-26.something cruising at 70mph, but through these states, this dropped to the low 23's. As soon as I noticed this, I refueled with the highest grade Shell I found (93 I think) with no improvement.
Could it be that some states put more ethanol in their gas that what we're used to here in New York?
Anyhow, finished the 4,353 mile trip at 24.6 mpg vs 25.5 for the exact same route last year.

I'm more of a Mobil person, I have Chevron, Mobile, 76 and a Shell gas station all within 1/2 a mile of where I live. For some reason the car just seems to be more responsive while on Mobil.
Probably my head playing games or something

I know that states that require emissions testing usually require higher-detergent gasolines be sold...
Maybe some of the no-emission states aren't requiring the hight detergentcy levels in the gasolines....

Ohio is only one of 4 states in the country that has no mandatory fuel quality inspection. They do measure pump accuracy, but make no inspections as to quality or octane of the fuel.

There was an interesting article in the Chicago Tribune regarding gas quality. All gas marketers (Shell, Costco, Exxon, etc) buy from the same set of refineries. These refineries are required by the Fed Govt to have minimum quality and detergent levels. The difference between say a Shell vs. Costco is that Shell takes the gas from the refineries and blends addional additives (such as additional detergents to keep valves clean). This explains why Shell gas tends to be more expensive than Costco.
The real interesting part of this article was that it would be cheaper to buy four bottles of, e.g. STP engine additive from the auto parts store to use every three months with Costco gas than the incremental price difference between Shell vs. Costco.
I still only buy from Mobil, Shell or BP.
