I've never liked shell gas for 1 reason, but today 2.
the first being, it always costs more no matter what.
the second stems for my Ranger
the people who owned my truck before me used shell exclusively, they had to put 92 (at the time) octane in. When I bought it from them, they told me if I didn't use 92, the motor would ping constantly.
So after the tank emptied out, I decided to test that theory and I put Unocal 76 regular unleaded in. Not one problem.
after that tank, I put 10 gallons of shell regular unleaded (87) in, and yes, I noticed a ping.
I burned 5 gallons up, and filled up on Unocal 76 regular unleaded.
the pinging stopped. Next 3 tanks were Unocal.
I then went to Arco because I was out of town and didn't want to use Shell. Not one problem.
Well fast forward 15 years, I use cheap fuel, Costco mainly, Valero if I'm deathly low (cuz a valero station is across the street from me). No pinging, no problems.

However, where I live, there's 3 gas suppliers, shell, chevron and this one called golden eagle. Of these 3 refineries, I know that wherever you go, you're getting one of these fuels.
You get the same gas, but their proprietary additives.

So all you can do is hope you're getting what you're getting.

My point exactly. I don't understand the arbitrary "gas X is better than Y" posts. There are minimum quality requirements anyway.
Throttle response, power, power availabilty etc. Things Sentient beings might notice. Oh, thats right we are in the Dark Ages - Part Deux. Flat earthers rejoice!


Quality requirements and Top Tier policing is a Joke.

You really notice that big of a difference in power from one brand of gas to the next? Your butt dyno is the most sensitive I've ever read about, in that case.

I've never seen anything conclusive, but I'd bet the average person can't even detect a 5% change in power output. It's why companies who sell air intakes claiming 7hp laugh all the way to the bank.

With those two brands, I would go by price, unless the Exxon station is poorly maintained and a low volume station, increasing the chance of getting contaminated or stale fuel (then I might pay the 15 premium). I have Shell, Mobil, Chevron, 76, ARCO, and USA stations within 1.5 miles of my house. I normally go to the Shell or Chevron stations, but will also buy from the Mobil or 76 stations (I drink the Top Tier koolaid) if they are less expensive or more convenient.

No matter what gas I put in my old and probably deceased 67 Beetle , it still took about 30 seconds to reach 60 mph and that was if I left the wife I use to have standing at the gas station,,,of course I always went back to get her,,,why?? I don't really know....

I do not see what difference it makes.

I fill up everywhere, never seem to notice a difference in the car.

Even knowing that almost all name brands gas are similar I still prefer Chevron more than any other, if they are few pennies more I will fill up there, if they are more than 10 cents more then I will fill up at Shell, Mobil, 76, USA gas ...

In my area Shell is usually less than others by about 2-10 cents a gallon, Chevron is the most expensive more than 10-20 cents more than USA gas.

Having hauled gas and diesel up until a few years ago, the gas at every station in a particular area is getting their fuel from the same terminal locations. And those terminal locations are getting their fuel from the same refinery, though the refineries will play a round robin kind of thing once in a while.

It was hit upon correctly, that gas is the same, only the additives may be different. When I would load a tanker, I selected who was getting the gas. The system would dose the gas as it was loaded with the additives that the customer wanted. Now, to that end, all the easily recognized name brands are getting just about the very same gasoline and additives. The only differences are between them and the regional convenience store kind of gas stations, which will only request a very basic, minimal additive supplement.

Just go with the best price you can get your fuel for. Forget the silly nonsense about who has the best gas. It is true that maybe the load the Chevron got down the street got yesterday was from a different refinery, since the terminal may have switched suppliers and the load the BP down the street is different today because of that switch. It jumps back and forth all the time.

Brand loyalty is really something. But a simple look behind the scenes can really be an eye opener. But some will continue to where blinders and claim one brand is better than the other. They just know!

Or, when you have Petro-Canadas up here that prefer to temporarily close a station rather than buy their gas from someone else.

Assuming your vehicle recommends 87, use that and you'll save FAR more money than worrying about competing brands...

Me I'll use Shell and won't go near a Exxon station... All that stems from a 5.0 Mustang I owned that had a unexplainable buck/surge that turned out to be Exxon gas... Now this was in 1996 and I've bought their gas exactly twice since then, only when I was low and not sure where the next station may be... The 5.0 stang??? Sold it in '97...

Now that you mention it, you're right. I believe it was a couple months back when they had a supply problem here. Shockingly, instead of using that as an excuse to raise the price, they left that alone. They did state that they wouldn't buy fuel from anyone else unless absolutely necessary, and just switched the pumps off at the south Albert Street locations. It only lasted a few days.

Thanks for the insider info. Shell's gas is nitrogen enriched, in which step does Shell do that? after the gas is loaded to the gas station tanks?
