Gasoline brand preference?

I had a friend who logged his mileage based on where he filled up his car. Almost all the major brands resulted in no difference in mileage. The only brand where he consistently saw a decrease in gas mileage was the Arco brand of gas. He saw on average a 10% loss in gas mileage from Arco.

As for me I'm usually a shell guy. And really only because it's the closest station to my house.

Does anyone have a preference on using non-ethanol? I've noticed my 2.5l seems to run slightly more efficiently when I run it vs. 10% ethanol fuel.

Yup, but non-ethanol fuel is hard to get around here and more expensive. Ethanol contains less energy than gasoline so your engine produces less power on the same amount of fuel. You end up burning more "gas" to go the same distance. That's my theory, and I'm sticking to it.

I have zero preference for any particular gasoline brand. As long as I've been driving, well over 50 years, no brand has every caused a problem or caused my engine to run any differently. The cheaper the better. And 87 is as high of an octane as our engines need.

And running a higher octane like 89 or 91 will help nothing... it won't give more power, more cleaning additives, burn cleaner, none of that. None of those are the purpose of octane. :)

I use Shell because it's the closest and always use 87.
Non ethenol is easy to obtain around here but i only use it in all my small engines, 2 stroke, 4 stroke.

I knew you got "less bang for your buck" out of ethanol fuel, and I really can confirm that running the 4 banger on the highway.

I guess I'm lucky here in Mississippi. More and more stations are getting non-ethanol fuel, and it's usually only slightly more expensive. Maybe 20 cents, which is worth it to me since my Jeep sometimes will sit for weeks and months.

I actually prefer the Valero brand as I do my little part in actually refining it. Also they are the largest American refiner. Although when on the road such as the next planned vacation traveling from deep south Texas to the Black Hills of South Dakota and back, I usually try to stick with a major name brand......cC

No preference here. But I refuse to buy gas from any station that requires me to prepay inside before I can pump.

And where I live, there's quite a few small stations that require that.

I only buy from stations where I can pay at the pump.

As a former fuel tanker driver I can attest to what others have said. With the exception of ethanol free and octane, all other blends are about 98%(POOMA) the same. Some companies blend additives but from my experience those are just "gas stretchers" for lack of a better term. At the distribution level fuel retailers sale in such a large volume that even diluting your fuel with additives at 0.1% could result in slightly higher profit margins. These additives are not there for your engine performance, but instead there for their profit.
Also there are winter blends and summer blends for your more heavily populated areas. Even that is only the RVP(vapor pressure). Lower in the summer and higher in the winter to make sure the gas can evaporate at lower outside temperatures. At proper operating temps this has pretty much zero effect on performance.

Edit : Thought about "gas stretchers" as soon as I hit submit. In the winter some companies add Butane to their fuel mixtures. Butane is clean burning and cheap. The perfect example of what I refer to as gas stretchers.

How's your new jeep so far?
Love it! About 200 miles from home right now. Had insane winds and rain with bald tires so I am driving straight to a tire pros to get some new ones on. So totally stoked with this lj. I can't wait to test out the lockers on some trails. It's nice having cruise control and not having to shift at every incline! Cracked the windshield twice driving though! 1700 miles later it's still purring like a kitten. When I first picked it up I turned the AC on (I love AC now that I have it haha) there was a HUGE amount of water that sprayed on the pavement from the engine compartment. I thought something was leaking but the temp gauges didn't move and I found out it came from a little 1.5" tube from the fire wall directly where the AC and blower motor sits from inside.. I assume it's just condensation that had been sitting for miles upon miles and the AC hadn't been run in a very long time. Gonna try to remove the crap paint job in the next couple weeks with a pressure washer. If not that, a buffer and clay stone.

Wow... Up here non-ethanol fuel (when you can find it) is $1 or more per gallon over ethanol fuel.

Just got out of Oregon yesterday. Higher gas prices than I ever expected. Almost as much as Southern Cal.. and you can't pump it yourself lol

Can't pump your own in New Jersey either. Old school labor laws from the early 50s. For some odd reason labor unions have been successful in keeping them on the books in these two states.

That's what we call price gouging down here... That's insane! I wouldn't pay that much extra for non-ethanol either. Definitely not worth it in that case.

99% of the time I use Arco. It is the cheapest and since I drive 75 miles one way to work (not in the TJ), I need to save as much as I can.
