I think the manual recommends every 15k. ...assuming you're running a stock pulley.
Use a spray pump, like from an empty bottle of Windex, to siphon it out into a soda bottle or something you can cap off.
You'll need two (actually about 1.5) of these: GM#12345982

I have been using 5w30 synthetic oil and change it every other regular oil change. That is probably about 8,000 miles. I estimate that I change my oil every 4k.

Seems to be working ok.

Replace? Naw, just top off when you hear the rattling sound from under the hood.

Oh, your results may vary.

Several people I've talked to have said that only top-offs are required for the life of vehicle and that you don't have to change it.

My dealer actually said they've never changed any supercharger oil before, just check the level to make sure its not going anywhere.

I suppose it wont get "dirty" like engine oil but I'd imagine some wear material ends up in their.

hahahah...okay.

Do me a favor....leave it in there till around 100k, then pop that cap open and sniff it reallll deep. Make sure someone is taping you when you do it...I need to see your reaction.

Oh man that is the worst smell!
Friction and heat break the oil down.
If you are modded and have a smaller pully you should change it more often.

na the dealer will also tell you the blower isnt rebuildable, or fixable. Ive done both to a bunch. But they can sell you new blower for $2,200 Ive seen.
