So i just recently bought the hp tuner, and while i haven't actually done any writing yet, i have been doing some scanning, and seeing what my engine is doing, while im trying to learn the software. I noticed that my car was knocking quite abit. When i talked about it with a friend he asked me where i got my gas, i started going to bp instead of speedway, and while i couldn't believe it about 200 miles after switching i noticed a big difference. So i guess i was just curious where do you guys get your gas, and what is your opinion on the quaility of gas from one station compared to another.

On a stock tune you car is going to knock like mad whenever the torque converter locks up. I've seen as much as 12* of knock on my Aeroforce. This happens regardless of the gas I'm using. Most gas is the same, the only difference is the additives that the given brand uses. Two that come to mind are Chevron Techron and Shell's V-Power.

Personally I use a BP and Shell station that are convenient to get to when I'm driving to and from work. (The BP is on the right when I'm going to work and the Shell is on the right when I'm coming home). I couldn't tell you any differences I've noticed between the gas from the different stations.

IMO it depends on the station. I go to a Sunoco and a Shell station for mine. I was going to a Marathon for a while till I noticed that water would spew out of my tailpipe by the bucket. Since I stopped going there I get a drip...maybe two.

For me it's 7-11 (quarles), Sunoco, and Exxon.

I've always seen Shell gas burn through my tank a lot quicker.
BP I will never get because the prices at BP stations are off the charts (Even before the BP oil rig explosion.) And I've gotten a lot of water and crap in the fuels as well.

Brand really does not matter. I prefer not getting mom n' pop gas only because I don't know the quality. As long as I'm getting at least 91octane in the car and 87 in my truck, I really don't care. Havn't noticed any difference, really.

I usually only fill up Sunoco 93

It's usually the cheapest near me, and it's what was in my car when it got tuned. Shell was not liked by my car (though it could have just been one bad tank, I don't go out of my way to go back to them)

Some gas stations use 10% ethanol in their gas (it's almost impossible to find pure gas in the north). Modifying the commanded AFR at idle will help make up for the ethanol.

That won't eliminate all your KR though, a MAF tune and some tweaking of the timing will help the most.

iffy. What can you do in a tune that would make the torque converter lock up less, or is there nothing you can do?

That's a question better suited for those with a tuner. All I know is when my TCC duty cycle goes up on my Aeroforce the KR readings go through the roof.

i like shell. BP no.Speedway NO. BP because of the old pending law suit with GM against them about their gas not being good for GM's style of fuel injectors.

speedway no because i filled up on speedway and drove home from indy to cleveland and my imp was mis firing al lthe way there when i gave it more than 25% throttle. got terrible mileage and i put marathon in and it ran smooth. i stopped trusting speedway. idc about the pts anymore

I want to say that's more false knock than anything else. I used to get a s**t ton of KR when the TCC locked because it would make the y-pipe of the exhaust bounce off the rear sway bar. Raised the exhaust up so it didn't hit and the KR went away

I wouldn't be surprised if it was mostly false knock. I might have to check the exhaust for clearance.
