Looking for info on the correct oil for servicing the supercharger on my '00 XJR while it's out of the car. I've seen a lot of posts detailing how to do it, but other than the Laco Zoom Spout product I've not found a definitive answer for what type of oil to use (and no one locally has the Zoom Spout product ).

 

GM supercharger oil at any dealership. This is the answer

 

I replaced my fluid last summer, bought Eaton supercharger oil on ebay (8oz), comes with suction pump to pull out most of the old oil, a lot cheaper than from dealer, remove front allen access and just suck out the old oil and put in the new, you will have left over oil, I belive about 1/2 so will have enough for another change.

 

@powell
So much oil you used per change? Only 4 oz?

 

yeah the supercharger is an Eaton M112 4th gen and takes .250ml of fluid, it is sold by dealers (ford and chevy) in 4oz or 8oz amounts. found one 8oz on ebay for lot less than the dealer and fairly sure got most of the oil out and just replaced until it started to come out of the filler hole on the front of the supercharger.
I did the same with my trans, bought the mercedes fluid on ebay for about 12 bucks a liter vs the 47 the dealer wanted, my car has a drain on the converter so I got close to 8 liters out, just measured the amount and put back in what I took out, its working great after 15k miles.
