Are all gas stations the same?
Ive always heard mixed stories about the companies. About how the gas isnt good quality or some crap like that. But I only use Mobil, Shell, and on the occasion when I really need gas is 76.
my dad used to be an exec for mobil about 10 years ago, and he was always asked this question and he would say all this random stuff about their process. after he left whenever he gets asked now he says its all the same 
and most small gas companies buy gas from the large companies. a family friend of mine owns about 100 stations in arizona, most mobil and some with a bunch of randomly named ones too... all get their gas from mobil.

76 is a united oil brand along with arco and their refining process isn't as good as cheveron. German car companies say to only use cheveron when you don't have 93 octane around. Cheveron, shell, and mobil are not part of united oil and they all do their refining by their own companies.
In my VW, I had to run 91. My VW mechanic had independent tests run on all the major fuel companies, and ARCO was by far the worst. ARCO's seemed to eventually rot rubber tubing in the cars (fuel lines, seals, etc.), and created a knock. I believe he concluded that Shell was the best, and followed by 76.

I run either chevyron or 76. Ive heard Shell's v-power uses a sulfur additive which kills fuel level sensors. I used to run only shell and never believed the sulfur thing until my level sensor took a crap a few months into running only shell.

76 is owned by ConocoPhilips.
If you're referring to Union Oil/Unocal (not "united oil"), they don't exist anymore. They merged with Chevron years ago.
After years of testing gas stations in many of my different vehicles (Corvettes, Trans Am, Bikes, 4-bangers, trucks) i have come to see that CHEVERON is superior...after looking at gas mileage results, and performance... i choose Chevron. ALTHOUGH it is pretty BAD *** how 76 carries 100 octane!!!

what gangbang said is pretty much acurate but arco additives are not as good as most. the reason why arco is so cheap is because they make most of there money on customers buying crap from the am/pm. there profit margin is much higher inside the store then it is on gas.
