Today I learned ...

As I recall it is some really odd smelling stuff too.
I'm impressed that you know how it smells. That suggests that you've used it, which suggests that others here have used it as well. Have we ever had a thread or a discussion about supercharger oil?

Wasn't my car. Just an Eaton blower on a friend of mine's that I helped install and later, change the oil on. He ended up getting the oil from the local GM dealer since they were using similar blowers on the Pontiacs at that time.

The used oil was stinky, the new stuff wasn't much better.

Don't know if it has changed over the years or not. This was probably 20 years ago or so.
 
I had a supercharged 3800 in an Olds 98. Changed the supercharger oil at 120k miles (ish). Volume needed was only 6 - 7 oz. Old oil was black and stinky, new oil was clear and stinky. Was an easy to do
service.
The Olds had about 240k miles on it when my son sold it. The supercharger was getting noisy by then, but still going.

There's been some discussion over the years:

I used to own a 2004 Monte Carlo SS Dale Jr. edition with the supercharged 3800 and I changed the supercharger oil in it with the AC-Delco oil from the dealer. I think the car had around 95,000 miles on it when I changed it. I just did it as preventive maintenance.
 
I changed the SC oil in my mother's Park Ave some years ago. Smelled like a$$ and I recall it took just enough to require you buying 2 bottles of the GM fluid.
 
What makes supercharger oil different from regular engine oil? What characteristics or additives does it have (or not have) that makes it supercharger specific? Viscosity? hy does it smell so bad?
 
Some here seemed to change theirs over 75,000+ miles mark. I would cringe leaving that small amount of oil go so long. I would have to dump at 5,000 miles, then at 25,000 and then at 75,000, and so on.
 
I own a Toyota Previa. After 1995 they added the supercharger to meet market demand. I knew from reading about them that they had supercharger oil. Kinda funny having to change supercharger oil in a soccer mom mobile.
