Stock 2000 GTP 70,000 miles owned since 30,000 and plan on keeping. The supercharger oil was “changed at 20k” by dearlership. I have asked the service people at 3 dealerships about changing it agian and was told “we never serviced a supercharger before”. so my question. Should I do it / have it done or run it till it dies. ---

Should I do it / have it done or run it till it dies. u can change that but I think ur in need of a new pulley. With that many miles I would go to a 3.4 pulley or a 3.25 like Im running right now. 🙂 ---

For her this thing needs a de-tune, a 12 point and a chute incase she misses a turn and needs help landing. LOL ---

dealers dont like to cange the oil-they would rather fill clean on top of dirty or warrenty the sc out. you need a vaccuum pump like the one eastwood or griots has(great investment) after it sucks out all the nasty oil youll need 2 and 1/3 rd bottles of gm to fill.(thats how youll know its all out) i changed mine and the pitt club gp out all the time. ---

This may sound dumb but which plug is for the oil? When I had the cover off doing other work I noticed a few plugs on front passengers side either allen or square I can’t remember. Just a refference point will do. ---

Thanks, Next mod SC oil change that’s got to be 50hp if I get a sticker with the oil. Have you guys had electrical problems with GP’s. I had my share but don’t want to keep a money pit if what I have seen is just the beginning. ---

only one was a resister in the pass fender recall causing the fp not to come on. hot wire the fp for 20% more pump and it will be bypassed ---

I was just wondering because mine has caused some sleepless nights. Shift park interlock $500+ Rear speakers no signal ? Evap control wire 1 week in my garage and $50 later found bad wire in loom. Now low coolant light. Rad full and Advanced claims they can’t get the sensor. They list a sensor but it goes in the overflow mines in the Rad. So now I get to pay way to much to get it from GM.
