How often should i chg sc oil?

Note the ester base fluid is corrosive to plastic, and is designed for a non-maintenance system.

Note my link from KB which suggests motor oil yet a 12 000 mile oil change interval.

I'm in the process of collecting temperature data as we speak.

I changed my supercharger fluid after 75K miles because I was getting some whine. I went to the dealer, got two bottles for like $12 and changed it out myself, whine has calmed down a lot.

Yes it smells, just use a cheap $1 squirt bottle to reverse syphon out the old fluid and just pour the new fluid in, make sure the engine is cool.

I always put the used SC fluid in a plastic bottle. Not sure why, but I have always done it. Hasn't eaten through the plastic in 5 years.

But in case you didn't know, eaton and KB are not the same thing. They are two totally different manufactures of supercharges and what one recommends for their design, the other may not. If case you didn't know.

Edit:
Also, if you are interested in educating yourself, read up on esters, which is what GM supercharger fluid is:
