Where do you fill up?

[CHOO CHOO]

Chevron w/ techron usually. When I first got the truck, I started w/ 2 tanks of 87, then 2 of 89, and lastly 91. Despite the price listed on the street markers @ gas stations I've realized a tank of 87 vs 89 vs 91 is only $4-$6 per fill up. Considering the trucks drive ability is supreme w/ 91, IMO, I just use that.

Yeah, I always use 92 or 93 oct. Like you said, its only a few bucks more so might as well have my tahoe drive better.

Soulsea, I have to disagree with your article. If all the gas comes from the same place, then why do all the trucks look different and come from different refineries? I'm going to use Salt Lake City as an example because that is where I'm from. In North Salt Lake there are a few refineries, and each of them have their own companies logo that is visible to the public from a good distance away. These refineries are where the fuel that goes to gas stations is sourced from. If the gas is all the same, and comes from one source, why are there all these different refineries? Why did GM conduct its own testing and determiner who was Top Tier, and write a TSB on it? GM wasn't the only one. Mercedes and a few others did this too. It's just like the oil debate, are all oils the same? The answer is no. Ashland bottles Valvoline and Parts Master oil. Parts Master is cheaper. Why? It lacks some of the protective qualities as Valvoline, thus I would never recommend using Parts Master ATF type VI synthetic transmission fluid which is used in GM vehicles. Even if the gas did come from the same place, I would wonder why each refinery has a different holding unit for each type of gas.

each refinery has a different holding unit for their specific brand because each brand has markers in it to say that its that brand when tested by the government

edit:

place where i used to work ended their contract with BP because some BP branded station in like KY decided to run unbranded fuel, same stuff but they got fined up the ass for not having the markers saying it was BP fuel

I was going to try e85, but each station is 30min away from me in either direction, so I'll spend the extra dollars on pumping 91 locally, plus e85 is hype.

I'm not entirely sure if I buy into that Serge. When Justin did my in person tune, even though I had 87-octane running in the tank, it was showing alot less of an octane actually being burned. First thing he asked was "where did you fill up at?" Then suggested going elsewhere because the octane wasn't burning at a true 87. Atleast that's how I understood it. But who knows... not that big a deal for me, truck runs good and gas is what it is.

QT. One near the house and one near the office. They usually get my business. However, if the chime dings, I start looking for the closest station around. I found out early that my doesn't ding just when it's low, a ding on my Tahoe means start looking for a station - NOW.

Costco or QT.

I have seen many of the same articles that soulsea is posting. The only thing I have read that is any different is that a few do not use ethanol (though it seems VERY few and perhaps getting to be none... Around here at least) and that seems to make bigger difference than anything else they do.

Damn, 33 miles to the nearest ethanol free station....oh well.

I always go to Quiktrip. If that's not available I stop at Shell stations. Either way I fill up with Premium gas

...Oh..errr, except the premium part. 89 all the way!
