Gas is pretty expensive in my area. Is there a difference between am/pm and chevron for example? I hear that shell is the best to use followed by bp. chevron and am/pm are the only 2 stations closest to me, otherwise I have to drive like 5-8 miles. What's the difference in gas at other gas stations?

I never buy any gas from a station that's name ends in "O"

Or any of the small family owned stations

I prefer 76, but also purchase Chevron, Mobil, and Shell.

good rule of thumb is always get gas from the newest gas stations because they have the newest tanks and never get gas while a gas truck is droping a load (or for a lil while after) cause it stirs up sedatives in the tank.....

When I used to fill up every other day, I found out the following:

15.5 gallon tank (94 Camaro)
Same route, drive type, hours every day...I tried to always use the same pumps and fill up around the same time.


If I went to Arco, which was on the average 10 cents cheaper per gallon (not counting the 45 cents to use your ATM, which @ 15 gallons, now raises the price 3 cents per gallon). I would fill up with 14.75-15 gallons. (21.6 mpg)

Chevron (usually 15 cents more than Arco) Fill up would take 14-14.5 gallons.

Mobil (usually 5-8 cents more than Arco) Fill up with 13.5-14 gallons

76 Fill up with 12.75-13 gallons. (25.4mpg)

This was when gas cost about $1.85 per gallon. Lets round up and say 2 (not 3-4 like today). My two day round trip used to be 324 miles. (81 each way)

So just comparing the best (76) and worst (Arco) by thinking I was was "saving" 10 cents per gallon, I was actually wasting money. 15 gallons x $2 = $30 fill up (or $30.45 if paying with ATM). By going to 76 and paying $2.10 x 12.75 gallons, my fill up was $26.75. Weird huh.

What was even funnier, about 2-3 years ago, right before gas hit $2/gal 76 was actually cheaper than Arco for about a year. Now they are back to about 5-10 cents difference.

Everyone says Arco gas sucks. How does everyone know this and what's the basis? I've even heard some idiots say the gas is "watered down," whatever that means. I've run Arco gas when in a pinch for money and I feel no difference with the way my car runs.

What year is your Burban? I have an 02 that I bought used with 89,xxx miles. I have just under 200,000 miles and the car has been run on Arco since I bought it. The truck has been to Mexico over 40 times, since my GF's family is from there, and we drive down to Rosarito, and sometimes further, every time. There isn't a choice but to fill up in Mexico, but even then, my truck still ran like a champ with no issues whatsoever. Still running very strong, doesn't burn any oil, and I had no problems passing cars on the passes coming back from Vegas over the weekend with a full load of cargo and a trailer.

No longer have the Burban. It was a 98. Ours had i think 119,000 when we sold it? older gen motors, so cant really compare.

I have always put Arco in my car. I had Arco premium in it when doing the cruise to SD and then the dyno shown in my sig the same day... Then again I also put Seafoam into my car so I obviously don't care if the engine blows up. :P

You guys should go to the Signal Hill filling station, then you'll change your mind about your "good" gas. :D

I can't use Arco or Chevron they both make my car KNOCK like a mofo, I have tried 4-5 seperate times and come to the conclusion that Shell, Mobile and 76 are superior gas suppliers. I do have a scanner so i was able to physically watch the change from tank to tank with no other change but the gas itself.

This was confirmed by my father in his El Camino, so i usually prefer 76 if i can find it, and refuse to put either of the above listed "bad" gas brand in my car now.

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 :lol:

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.

Looks like it's slowly widdling down to 76. (I hate carpcar, but i guess they use their fuel for a reason)

Arco is owned by BP.

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.

im sure all the oil is the same its just how its refined and what additives and ethanol are used that makes the difference

so far 76 is the winner

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 ASS 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.

You people are crazy--gas is gas is gas. It's all the same thing! It all comes from the same pipe! The only difference is the additives added by each gas company. Jesus Christ, read a newspaper.
