who makes it and where can you find generic stuff.
I want to do an overnight soak to remove lots of carbon.
Just did a compression test on 95 Rora lowest was 185
(piston top looked clean on that one) highest was 220 and piston
had alot of carbon buildup.
all the rest were in the 200-210 range.

GM makes it. IIRC it's about $7 a can. Nobody else makes a formulation similar to it.

Yeah I was asking this question a little while ago. Just go to any GM dealer's parts area and ask for it, won't be much. There is a generic alternative, which is SeaFoam, and you can get that in a typical auto parts store. It works well, but not as well as GM's stuff, if you ask me.

Seafoam is like water compared to GM TEC.
For that matter I have used water but this
has too much build up.

These people SWEAR up and down that it works great. Dribble water into that hose and it will work just as well.

How does this stuff work? I keep hearing about it. something you should do on a regular basis?
03-16-06, 11:45 PM
Maybe every 25000 miles?
Seriously, you won't need it if you WOT your car regularly, and use decent gasoline. Lay off the Sunoco Swill, or gas from cheap crap gas stations that you have no idea whose fuel they sell.

Oh OK, i just researched it actually but its all good. I used to hammer the gas all the time, but to preserve the trans and diff etc, I generally keep it under 4500 all the time. I just blasted it to 6000 all the way thru 1st and 2nd today passing left lane bandits on the shoulder. I'd say I WOT about 3 or 4 times a week.

Lay off the Sunoco Swill,.
What's wrong with Sunoco? I always fill up with their Ultra 94.. too bad this is the last week of 94 in the tri-state area. :confused:

It burns quickly in my experience in every car I have used it in, has 10% alcohol, and the 94 is a waste of money. I'm 99% exclusively BP/Amoco 93 with Mobil 93 or Shell 93 if I absolutely have to. Shell seems to burn fast evry time I buy it though, but not as bad as Sunoco.
03-17-06, 10:35 PM
I just looked at the sunoco pumps today and 93 was ultra now. Why the hell did they do that? Its bull. I always used 93 before now its gonna be 91 lol. Oh well, the engine requires 91 anyway but still.

Around here they have five types I believe.
87, 89, 92, 93, 94.
