Supercharger Oil Change Interval

[Foogie]

Anyone have any data on if/when we should have the oil changed in the supercharger unit?

I think the supercharger unit oil is considered a "lifetime fill".

If one is worried about it, 100k miles might be reasonable, see below from Eaton;

"Q: How often do I need to change the oil in my supercharger?
A: The sealed oil reservoir in a supercharger is designed to last the life of the vehicle. Changing the oil is not recommended unless you suspect contamination, leakage, or other issues like bearing failure. Also, if your vehicle has an abnormally heavy duty cycle, such as racing or towing, you could consider changing the oil at regular intervals such as 20k, 30k, 50k, or 100k miles depending on usage.

Q: I’ve decided I need to change the oil in my supercharger. How do I do this?
A: If you do want to change the oil there is one fill/drain plug on the front face of the front cover. It will probably be an Allen type plug. You will have to suction out the oil using a syringe or other method before replacing with new oil. Fill levels are dependent on application. New oil can be obtained from any GM or Ford service parts facility, or from one of the Eaton aftermarket supercharger partner companies or remanufacturers. Please make sure you do NOT use any other type of oil, including synthetic motor oils. These will cause failure.

Eaton doesn't recommend changing the oil unless the car is used for racing or towing
