Since I recently did an oil and filter change and am waiting on my transmission service kit to arrive, should I just change the supercharger oil while I'm at it? I haven't done it nor have I checked it out because it's running well so far. However, I'm reading over my service records and see zero records about or for the supercharger. My idea is it's running on the same oil it came out the factory with. If that is so, I'm an idiot and have neglected to do anything about that until now. Should I change "150k" supercharger oil or leave the "lifetime" oil that's in there ?

Ive been reading up and it seems fairly simple on our v8 kompressor bros. Not too many parts need and most have done it in under an hour. The ones I've been reading/watching have been the syringe method where they get syringe pump with a tube and wd-40 straw taped into it to get as much as possible. They removed the belt with a wrench before doing all of that of course. I could do some much needed service in one go with very little spent on parts and labor. What method do y'all recommend ?

which fluid has worked best for you if it wasn't Mobil 1 jet oil?

Maybe just keep up with the recommended Mobil 1 jet oil ?

Mobil 1 jet oil is the right stuff, I plan on doing my this summer.

yeah i I figured the Mobil1 jet oil was still top of the food chain for our superchargers. I was curious to see if anyone has tried something else recently now that it's 15 years later and oils/fluids have advanced. Guess not for our cars

I’ve done it. It is commonly called Mobil Jet II, and you only need about 200cc of the stuff for a change.
You will also need “Ball end” Allen wrenches and pretty sure it’s the 5 mm size specifically.

Most will tell you the oil that comes out is dark and skanky smelling, so a change is a good thing.
I have about 500cc of this fluid left over from 2 swaps on my kompressors.
Send me a PM if you’d like 200cc of this for $10. I’ll probably never use it.
