Best Brand of Gas

Hey All. I did a quick search and did not find information on this topic, so if it has been covered please accept my apologies and if you could link to the thread I would appreciate it.

I just bought a 12 JKU sport, and I wanted to know what brands of gas do people prefer. I have always been pretty partial to Shell, but have people had better experiences with others? I will be putting the majority of the miles on the Jeep via highway. Not so worried about MPG, but rather if one brand is better for today's engines than others.

Mitch

No not really. Gasoline differences are in the additives. Just run a high detergent quality gas. Top tier listings are available online but all the major brands fit the bill.

Not to start an argument, which this topic generally does, but I try to stick to Chevron or Shell. I am running Exxon right now as the closest store has no ethanol Exxon. A store in town has no ethanol Shell so they are my two favorites at this moment.

I always notice Shell's gas burns slower and Exxon so I stick with those 2. Tried Valero and notice it burns faster...

Interesting, do you have calculated MPG numbers to share?

I don't know if brands make a difference, although I tend to stay away from the smaller stations. I always go to the high volume stations , my theory being if they have a tanker in there every 2 or 3 days , I'm assured of relatively fresh gas for better performance . Slower moving stations, l think, the quality goes down as the gas sits longer and mixes with water condensation also in the tanks. Seems to work for me...

Brands do make a difference. Recently toured a pipeline facility where additives are put into the fuel before going out to the stations. The rep stated that Shell and Aamco are the best and will give 15% better mileage.

Many of the guys have tried making the switch from brands such as wawa to shell, myself included, and have all seen better mileage. So far getting about 2mpg better overall. Some guys have gotten 40+ miles per tank better. I'm sold on it.

I try to stick with 76 gas. I drive all say every day for my job and have found I get the best mpg from them. There is not a noticeable difference in performance in any of the brands I have used.

You do get better gas at better stations. I filled up on some Indian reservation station in CNY a few years ago and got like -2mpg and it ran real rough. Very noticeable.

Not yet just got my Jeep last month but my prev was a G35 coupe and just based my experience from using it for daily driving to work and back I paid attention to my fuel gauge and how often I filled up. Maybe just from using 92 gas?

Plus Valero corporate is here where I live in San Antonio so you hear the rumors of how they use more additives (watered down is what they say lol) than other competitors so they can advertise that 1 to 3 cent cheaper gas...

Exxon > BP > Shell > Others for 87 octane

According to the article, see the reference below, here are the amounts of detergent per brand and octane. So, for 87 it's Exxon > BP > Shell > Others. For 93 it's Shell > BP > Exxon > Others.

BP 87 Octane ... 17.2 milligrams per 100 milliliters
BP 93 Octane ... 26.4 milligrams per 100 milliliters
Citgo 87 Octane ... 6.0 milligrams per 100 milliliters
Citgo 93 Octane ... 9.4 milligrams per 100 milliliters
Exxon 87 Octane ... 20.0 milligrams per 100 milliliters
Exxon 93 Octane ... 21.2 milligrams per 100 milliliters
Pilot 87 Octane ... 5.8 milligrams per 100 milliliters
Pilot 92 Octane ... 8.8 milligrams per 100 milliliters
Shell 87 Octane ... 16.2 milligrams per 100 milliliters
Shell 93 Octane ... 31.0 milligrams per 100 milliliters

If you have a QT convenience store in your area, it's the same Top Tier gas as the big name stations and way cheaper.

Very well may be, but how can one be sure? Any gas analysis has been done?

By the way, by "Others" I refer to other brands in the list above, not all brands overall. I would expect Chevron to be among the front runners for example. Based on what I had read about their additive package. Wish test results would include other brands as well.

BMW says Shell or Chevron out here. Try 76 or Arco and they misfire. I usually stick with Chevron because Shell is always more expensive. Have run Costco gas in the Jeep with no problems and decent mileage.

The only difference I've ever observed is when I'm outside metro Atlanta and can find pure gas rather than the E10 crap, I always get a 1-2 mpg bump. Never noticed any difference between the gas at QT or Kroger and the fancy places that cost 10 cents or more extra per gallon.

I only run shell in my 3.8. Cuts down on the pinging.

I almost always go with whatever is closest/cheapest! I don't much care about the mileage aspect since I own it to enjoy it, not to worry about the cost of ownership.

That said, the two closest/cheapest to me are Costco and Phillips 66.

I've tried most if the brands in my area. I get better mpgs from 76 than I do from Shell. I've also found that I get 2-3 mpg less from Arco.

Exxon/Mobil. Their easy pass RFID token links to my grand children's college savings plan through UPromise. I also get $0.05 off per gallon.
Not a bad deal.
