What gas is best

Well i just had my car protuned and shane said he might have been able to get another 10-15 wheel out of it but i had some bad fuel in it. He said bp is the way to go. There isnt really one close to my house though. Is that the only station that is reputable or are there any others?

 

BP, Shell are good ones for sure, I want to say Amaco or something that starts with a M... those are the two best, No Holiday....

 

I have good luck with Mobil, also Shell.

Tesoro is decent too, but I haven't seen any around here. Its US Oil in Tesoro, too.

 

yea i heard holiday is just the worst. The owner of DB said he was tuning a shelby gt 500 and ran out of gas so he ran up to the holiday and got like 5 gallons worth and the thing started knocking at idle. YIKES!

 

BP non oxy for me

 

shell ftw..BP iFTW. mobil and marathon are decent if nothing is around

 

Why does Shane tell everybody that? Everybody that he tunes "has bad gas".

I prefer BP gas.

 

BP, Shell, and Mobile is all i will really run in the SVX... Preza, meh, any 89-92 is good enough for now. lol

 

the shell on zane always have cheap gas u know that ??

 

I'm a little curious what problems people are having with any particular gas, I fill mainly by conveniece. I have a stock powertrain and have never received poor performance out of any gas. when I had a 5.9 high output grand cherokee it would run better on bp/amoco gas, but I have not seen any drastic difference with a WRX. Is it the 10% ethanol that the state requires that people are concerned about?

 

Its not the ethanol, its the detergants that sa and holiday use, they carbon EVERYTHING up and knock like crazy

 

The best Gas is the one that comes out of your A$$

 

COnicole 66!!!

 

Here is a list of race gas non-oxygenated locations from Minnesota Street Rod Association. There is two SA stations in Anoka that sell non-oxygenated gas. I checked it out, the pump is labeled as non-oxygenated but 91 octane.

Bahaha, I was thinking the same thing!


I go out of my way to fill with BP non-oxy. Shell is really good, too.

 

bp in st michael has 92 non oxy, right off of 94!

 

Which is funny because I ran pretty much solely Holiday fuels in my turbo RS and never had a problem with it. If anything were able to find poor fuel that would induce knock it would have been that car. And when I changed the plugs on it they looked just fine.

I think it would be neat for someone with a stock ECU car to do a blind fuel test to see if they can tell which fuel is which. I doubt most any of us would be able to tell between same-octane fuels without having some sort of solid metric to look for.

I just try to use frequented stations, places I know the 92-93 tanks are refreshed often enough to avoid stale gas. I think that's the bigger fear of mine.

andrew there is a BP in Spring Park about 5 minutes from wills. Down the street a ways there is also an SA that has 100, and 110 octane race gas for a pretty decent price. That station is more like 7 minutes from victors.

 

BP is the only fuel that I run in our cars. In fact, I try to fill at the same exact station whenever possible.

 

Just make sure it is a BP with heavy traffic in an affluent area where people buy premium, otherwise it'll sit and give you some free water when you fill up.

 

How about plain old Super America gas? I use that most of the time

 

no, sa isnt good...but its not as bad as the dreaded holiday

 

Well in winter they add a good amount of butane to the gas to get it to light off, which doesn't have the btu of that which it replaced, so it is crappier (as relayed to me by my former refinery coworker). I've certainly noticed my gas mileage go way down, and I run BP now most of the time.

 

I agree with this, although my car is not modded, my worst fear is also "stale" gas. I think that it is intreesting that "non-oxy" and other addative fuels. I am going to venture to guess that "non-oxy" fuels don't have the ethanol "alcohol" content. I am not sure how many premium gasolines have no other detergents and I can't remember seeing any ads or claims to that effect. As far as pre-detonation "knocking" goes the ethanol content fuels would definatly have increased knock resistance beyond the posted "OCTANE" levels due to the decreased BTU content, unfortunatly this also makes these fuels less efficient. All things being equal I have yet to hear of an indivdual toasting an engine due to poor fuel quality. Given that the other possible outcome is poor power performance, wouldn't a Dyno run be in order?

 

I run BP gas from the station at the intersection of excelsior and lake. Lots of rich people using premium gas and good quality gas. I try to fill up at the same station every single time for consistency sake. If i have to get gas somewhere else I only get a 1/4 tank or so.


I used my 2 stroke scooter as a test of gas potential as different brands of gas had vastly different effects on it. It lost 3mph top speed on holiday gas and went 5 mph faster on BP gas. After that it was only BP for me.

 

So far my car seems to run the best and gets the best mileage on Amoco premium. I know my car shouldn't require premium, but I've been able to repeatedly get about 2mpg more with it... :dunno:

 

FYI everyone, while getting fresh fuel is probably the most important, and everyone understands how the octane scale works and what it means - gas is gas. What you guys are actually comparing is the quality that the station and station brand puts into keeping their storage tanks clean. Literally the truck that will deliver to SA follows the truck that will deliver to BP followed by the Holiday truck in line to fill their rigs up. I do trust different stations more than others though because of the standards put in place by their corporate headquarters and the strictness of those policies.

 

I prefer BP too. Not everyone has bad gas, but it is extremely common to have people come in with gas that limits the car. It isn't hard with an Subaru or Mitsu to tell if the car is knocking since they have great factory knock control. When someone comes in running a gas that you have had problems with before and you can't get much timing or boost into the car without it knocking, there is a good chance that the gas isn't the greatest. If they don't want to run good gas, then that is fine, we can tune it for that. I am definately a gas nazi though, all premiums are not created equal. I have cut tunes short and told people to come back after they run a couple tanks of BP through the car because the car would go into detonation way too easy.

 

Gas is gas until it comes out of the pipe and to the respective company. Then they all add their own additives. From that point on it's not equal.

 

how about bobby's & steve's? are they any good?

 

I use ONLY BP 93 Ultimate.

There is an Amoco on the corner of 35e and Hwy 96 in Centerville. They are the only place I am aware of close to me that sells 93.

DO NOT, and I repeat DO NOT use that crap Holiday and Super America gas in your tuned WRX/STi. I used that crap in my EVO when I had it because I thought Holiday 93 was the greatest thing and I had so much knock it was rediculous.

There was a thread I found one day when I had nothing better to do but surf the web and a guy did an extensive data log of an EVO or Mustang...can't quite remember the automobile using Holiday, SuperAmerica, BP, Shell, Conoco gas and it was amazing the knock/detonation that was going on when using anything other than BP.

Shell should be good also I would use them if I had no BP around me before anything else.

Those are my TOP 2.

 

They sell Mobile gasoline if I remember. Should be OK.

I would stick with BP first, then Shell, and finally Mobile.

 

you can get race gas at bobby and steves in northeast...

 

is M&H any good? It has 93 octane. That's what i have been using in my car.

 

It's ok at times, sometimes they get sh*tty batches, and my car runs like crap
