GM Top Engine Cleaner

Does it matter having a GT vs. GTP to use this stuff? Are the procedures any different, and if so, anyone able to tell me where I can find how to do it for a GT? Also, does it matter whether or not you follow up with an oil change? I've seen procedures saying yes and no as far as getting one after you clean it out. Thanks for the help:smile:

Maybe this will help. Not really very detailed.

Yeah, that's what got me curious in the first place, I'd rather not have to do the oil change if at all possible, but I'm not sure if it's needed to make the most use of the procedure.

With the top engine cleaner alot of the carbon deposits and crapola in the engine gets dumped into your oil...hence the need to replace it right away. You dont want your oil circulating that crap back around the motor.
