What oil would you recommend for a Pontiac GTP supercharger. The current oil has been topped off several times over the years but never changed. It looks dirty and runny so I figure I will just change it. I know that they have specific oil at the dealer for this but I had hoped that I would have something in the garage that will work as well.

I just got the stuff from ZZPerformance for the Buick. You can get the GM stuff at the dealer, I don't think much else can be used in there.
What does it spec and how long (time/mileage) exactly has the oil been in there?

It is animal fat based, most likely nothing in the garage you have will meet the spec. Use the supercharger oil it is cheap insurance.

Like others have said, regular oil will not work. Oil from the dealer or from ZZP will work.
While you're at it you should probably replace the coupler. They ALL go bad eventually. Plus, you get a nifty syringe so you don't soak your engine bay in gnarly-smelling supercharger oil. Plug your nose!

My Thunderbird SC also has an M90 on top. I changed mine about 7k miles ago with BP 2380 Turbo oil. I'm running about 15psi of boost, and its working great, no noise or anything. Quite a few of us SC guys are using this stuff in our M90s with good luck. Its oil meant for airplanes, which have much much tougher conditions than that M90 but similar in the high RPM aspect. Why you can't use normal oil is because it is a sealed case and normal oil expands when it heats up, supercharger oil and turbo oil won't do that under these conditions. So you can use the BP 2380 if you are comfortable with it, if you're not just buy the stuff from the GM dealership. You need 8oz for a full refill. BP 2380 is much more economical.

I've always used the GM oil, for ~$8 a bottle (need 2 bottle) I feels it's not worth to put anything but what's recommended.
I've always kept mine topped off and only changed it when I replaced my coupler (150k). Some guys change it every 30k.

Yup, that's why it is the funkiest, cheesiest, "gnarliest" smelling vile fluid this side of Motorcraft XL-3 diff additive (especially when it has many miles on it!!).

I used to have a '90 SC as well, a 5 speed in fact with a B&M short shifter on it.
Is there still a strong SC enthusiast/tuner community out there?? Is ol' Bill still alive and publishing "Chargin' Thunder" in the Carolinas?

I've always like those cars although i've never driven one
one thing that kept me away was how much aftermarket parts cost for it......
although very cool car from the era of cars I like the most....

I also am using jet engine oil, but I went with BP Turbo Oil 274. The GM stuff is 8 cSt at 100°C, but most jet oil is 5 cSt. The BPTO 274 is 7.5 cSt. Many people have reported good results with the 2380, so the viscosity probably doesn't matter much.

Thanks for all the info and comments. I will take a trip to the dealer just to be safe. Speaking of those early Thunderbird SC's, I had a buddy transplant one of those engines and ecu into a non-v8 mustang body. It was a very interesting car until he blew a headgasket on the way back from FL. He scrapped that car for $250 but we were all young back then and didnt know any better. I wish I would have bought it and fixed it.. I think it would make a nice daily driver as well as a novelty. I still have a photo of the engine (in the stang) around here somewhere. He wanted to do the same thing to a ranger pu but never did. I think he said it was a problem in a that application for some reason.
What are most people able to get out those SC T-Birds with mild-ish mods? I saw a pair running at the track last time I was out and neither one was any faster than mid 15's. I didn't peek under the hoods, but both had at least some exhaust work done and probably a pulley.
On a side note...I'm ready for April already. Going from a car running 13.1's @ 107 to a car that goes 0-60...eventually, is pretty difficult when the toy is in storage.

It ran a 14.3 1/4 in the fall, but that was with terribly dry rotted tires that would spin half way down the track. I got new tires recently, and I want to put a performance valve body in the transmission before spring. I'm hoping when the track opens in April I can get high 13's. Yeah, the stock exhaust is terrible. I switched out the restrictive resonator to a magnaflow muffler and ran 3" pipe all the way back to the split for the duals in the back. Took 4 tenths of my 1/4 time. It's such a fun car.
FYI: Most of the newer Mercedes Benz supercharged AMG (M113) engines use a Eaton designed supercharger on them. They take part MB part# 000 989 62 01. Supposedly, this is Mobil Jet Oil II (a low viscosity turbine oil). Mercedes wants $46.00 a quart. You can find Mobil Jet Oil II online for $20.
