Which gas stations have the best gas for these cars?

Murphies seems to be doing good in mine right now, Chevron did good too. but Shell totally drained my performance... but what about say BP or some others?

and would anyone know off the top of their heads what the different companies use for additives... i'm pretty sure murphies uses ethanol

 

I personally prefer Shell, definitely got about 20-30 more miles to a full tank then BP. BP would be my 2nd choice with Clark as 3rd.

 

all gas stations get their gas from the same place, gas is gas. only diff is, some dont clean their tank sometimes and u get crappy gas. iv seen it happen at a number of stations with my old car. There is no better or worse gas, they all fill their tankers up at the same hub. its all the same except for different octane ratings of course.

 

While gas is gas, so to speak, each terminal blends different additives based on the specs. BP gasoline has different additives than the no names. I'm sure Shell, Marathon & all the brand names have their own formulation. There are 3 different terminals within a few miles of where I work.

For me logging with HP Tuners, I see less Knock Retard on Marathon 93 octane than a no name or BP Ultimate. I haven't had a chance to log Shell. Nothing close & convenient to my commute.
The Marathon station I frequent uses seperate hoses for each grade, so I get all 93 octane, not a few quarts of 87 from the hose & pump, then 93. Something to consider when you fill up.

 

SHELL!!!!

 

my car loves sunoco ultra 93. that's all i have put in her tank since day 1.

 

I personally try to use sunoco as much as possiable. Sunoco has a seperate tanke for octane that blends with the gas as you pump. At other stations it can settle so you may not actually get 93 octane. Try to avoid stations the use ethinal.

 

i use exxon mostly but if possible i will fill with shell over any other gas.

 

I only use shell since day one. 93 vpower. Other than that ill put in bp or mobil if I really have to . On my ohio trip I barely made it to a bp because there were some bullshit valero stations haha and I told myself that I won't do that to my car

 

I think it all comes down to personal opinion. I refuse to get gas at places that there hi octane is only 91 and they charge u the price that would be for 93 ( the usual .20 over regulR gas). That personaly anoys me so I won't even get gas there in my jeep witch just takes regular.

 

Sadly, Sunoco disappeared from the midwest a long, long time ago. Also, there aren't any stations that I am aware of in my region that don't put 10% ethanol in the fuel.

 

??? There's Sunoco's all over the midwest.

 

depends on the state... none here in Missouri.

For those of you who know David Buschur, he did a gas test a long time ago and found QT (quiktrip) and Valero to be the WORST fuels available. His evolution running these fuels would get crazy knock across the RPM band. Flush the tank and change to Sunoco or Shell, no problems.

I'm limited to Conoco, which I do run their 94.

 

all of the sunocos in my area contain 10% ethanol, so there is no escaping it. 10% ethanol will not cause any problems. i have been running it since May 2007 when i purchased my ss/sc, and have not had one problem yet.

 

No Sunoco in NW In or NE IL. (The Region)

 

shell v-power

 

eff u all. theres only 91 octane here in so cal.

no sonoco. and we have valero....ick

 

well since in cali... only 91 i use chevron though...

 

What the **** is valero anyways. I've never seen it before my ohio trip

 

Sunoco. Some offer higher octane than 93 There are only like 10 Sunoco's here in NC. None are close to me though I tend to always use BP. I tend to get better gas mileage using it.

 

well i used shell 93 the other day and it made my car feel so sluggish... i used chevron 93 a few hours ago and my car feels fine... hmmm.

i've seen a handful of gastations with 95 i wanna put some of that in my car n see how that bad boi runs... i wonder if the computer will like it lol.

 

shell made all of my past cars feel sluggish. thats why i stay away from it with my balt.

 

I've been running non-oxygenated premium. 6mpg better than standard gas...

 

BP works just fine for me, Shell made it feel a little less enthusiastic

 

huh? non-oxygenated? lol does it say that on the pump?

i knew i wasn't going crazy... made my car feel like it was bogging... no "in the seat" feeling really...
