Thread: What gas do you use?

why would anyone put less than 91/93 in a gtp? isn't that harmful..

Cause Y'all in some parts of duh country don't think 93 is super unleaded. On a cross ****ry tryp I needed a little ole splash of go go juice. Pulled off the big road in the center of a cornfield and treked 5 miles to whut y'all called a Rogers mini mart and gas station. The choices werrrrr 85, 87 and 89. 89 was labeled Ultimate. Didn't seem very ultimate to me. Luckily I had about 4 gallons of 93 left in the tank and I took a splash of this inferior crap. Drove her nice to to a place with electricity and 93 octertane.


I fill up at Costco, yeah anything charged gets 93, as it's common in my area.

Kwik Trip is huge in MN/WI. They are constantly advertising their gas is rated "Top Tier". What exactly does this mean?

My 03GT runs great on their 87, and my belly runs good on their pizzas, donuts, and all their other food too. Milk, bread, and several other items are even cheaper than the local Cub Foods grocery store.

whatever the cheapest

I know this thread was a few months old and revived just today, but for everyone saying 93 "burns cleaner", you couldn't be more wrong.

All octane is is detonation preventer. 93 is no cleaner than 87 and 87 octane burns no dirtier than 93. They all have the same cleansing additives and the like at the same stations. The only difference is the amount of octane.

That being said I run 93 in the GP even though I rarely drive it hard. I'd rather have that extra knock prevention from gasoline rather than depend on the ECU to pull timing to prevent said knock.

i run 93 from the same gas station, then same gas station sells 110 also

Normally fuel companies add more detergents and stuff to the higher octane premiums compared to the regular gas. Thats where the cleaner burn comes from. But my gp runs on corn so it doesnt care.

No they don't. The additives are identical through the lines, except for the octane. The "cleaner burn" is an old wives tale.

my N/A has 3 degrees of knock with 89...wtf

Still only three cents more per litre than 91.

EVERYTHING here has at least 10% ethanol. except maybe the 87, which is why its more expensive than the 89 with E10. thinking about going E20 since its 95.

if it burns hotter wouldn't it burn cleaner? I have no clue all I know is my car just won't run on 87...

93 is harder to ignite than 87 so 87 effectively "burns hotter."

Again, 93 burns no cleaner than 87. People who put 93 in a car made to run on 87 to "clean it out" are following old untrue wives tales.

Since the gas prices have increased, and a broke my trans, I run 87 in the car, the difference is that i have tuned for it.

and for the doubters, i just got 31.2mpg (calculated not DIC) on a 340 mile trip with 3.29 gears going 80mph with about 400lbs of camping and detailing supplies
