What kinds of gas do you guys prefer? In my experience I believe that Sunoco and Shell are the better compared to Hess and Delta. However for the price I might put delta in. Those are really the only places I've tried.
are all fuels the same? I defiantly believe that the air has more to do with performance than the gas. More so than the octane of the gas.
I'm running a stock 5.0 with a knn air filter lol.
Out here I can only get 91 octane, and some gas stations only carry 89. I usually run 85.
I prefer 7/11 or texaco gas stations. Generally I end up at holiday though. I have chevron because of how much bad luck I've had with the gas pumps. I once put in 27 gallons in a v-6 cat at a chevron and only got 350 miles to the tank of gas with no real idle time. I honestly think that texaco uses the same stuff as chevron, but I don't think its watered down as much.
Holiday is the cheapest with the best gas mileage in my experiance, and maverick is the worst for mileage. At my old work I got gas at a maverick every day I worked. I think it went through 3 fuel pumps the last year I worked there.
I like the gas that comes in 2.5 gallon jugs, and is blue, lol
I don't get it often, what there is is usually left in the bottom of my dad's trailer. (He hauls gas, alky, and sometimes race gas)
Course, if it's on a stock engine, it doesn't do jack squat anyway...:hick:
I run the high octane nitrous enriched Shell gas in my Audi :) (only because it's literally around the corner from my house)
93 octane BP in my 88 T-bird. It's two blocks from my house ;)
The 95 runs the cheapest 87 octane I can find.
Sunoco Ultra 94 in both my supercharged birds(because i have too).
well, my last name is Gass....who the hell runs me in their cars?
85? Lowest we got here is 87....
I've been using Sunoco and Valero as of late....always 93....
My Dodge calls for 91, but the manual states you can run 87 albeit with reduced performance due to the knock sensor ;)
I live at about 5,000 above sea level, and there are parts within 20 miles over 10,000. Suposedly it affects your air to fuel levels.
the cheapest runs fine for me. I also go through 30 gal a week in my van, so it's a price thing for that one. The lincoln manual says use to use 87 in it.
you have a lot of beliefs with no specific reasons.
Amazing,
there should be a test one should pass before being able to join here:rollin:
yes... I assumed that when dealing with gas it usualy refers to power and fuel econimy. However we all know what happend when we assume things. I also haven't specified which octanes.
In Sunoco and Hess I always use 93. I believe that I get beter performance with sunoco.
As far as fuel econmy goes it's negligable. I believe that with my engine your not going to get better fule econmy with better gasses. For every day driveing youre keeping the engine at practly an idle.
The only time those extra octanes help is when my AOD is in thrid or fourth, and some asshole in a BMW thinks he can pass me on the right.
So I guess at this point I have concluded that sunoco offers a convinent performance fule solution.
If your engine is not set up to run on 93 octane you'll get no more power out of it than running 87 octane. If you're putting 93 octane in a stock 5.0 you are not getting any performance gain. You're just wasting money. I run 93 octane in my 5.0 because I have GT40P heads with higher compression than stock and my timing advanced to 15* BTDC. If I didn't run 93 the car would ping. When I had the stock 5.0 in the car it ran the same with 87 or 93 octane. There was no performance gain with the 93.
i get better gas mileage with 93, not really any perfromance gains, although mileage is probably a performance characteristic i would assume.
I ran 91 a couple of years ago for a full tank, back before it cost over $40 to fill one. I actually got the exact same on my old 86 cat as I did with 85.
Now If I would have played with the timing, I'll bet it would be a different story.
When I first bought my '96, I pumped 93 octane into it to see how it would run. My logic was that the knock sensor would tell the computer to bump the timing up, therefore it would return better performance and greater economy.
Well, I was wrong. Wishful thinking, though. The car ran like ass and began to give me misfire codes using the CEL. I went back to 87 and it's been running exactly as it should for the last 30,000 miles.
In regards to fuel quality, I've always been satisfied with BP. I once bought gas at a cheapo no-name place and the engine pinged like hell until I found another BP.
I have my timing at 14 degrees right my and filled up with 89 cause 711 was out of 85. I averaged 2mpg less almost all city. I wonder if my timing again jumped a tooth and i'm running retarded. I haven't had the car ping, and i decided to leave it at 14 based on how quickly it neutral revved. I also know my car won't hit wot with my bad throttle cable.
