Hey i was wondering how often you should change your blow oil i heard from somewhere every 30,000 miles and if so how in the heck do you change it any one know ??


Thanks
Jay

 

100K just to put fresh stuff in. And that is up for debate.

There is an allen bolt near the snout to fill it.

 

The LSJ M62 has a lifetime fill and should not need to be changed before 100,000 miles
But if you fell like doing it

How its done:
Parts:
You will need two bottles of GM supercharger oil, GM p/n: 12345982 , this can be purchased at any GM dealership

Tools:
Turkey baster
Short hose- needs to fit over end of turkey baster, and in s/c plug, about
6" long.
3/16 Allen wrench or hex bit

NOTE: Make sure that your engine is cool before starting this!

1-Unscrew the super charger oil inspection plug (a black plug at the front of the
super charger snout using a 3/16 hex head).

2-Insert the tube (that's attached to the turkey baster in to the hole and suck out as much oil as you can. This may have to be done many times to remove as much of the oil that you can. Dispose
of your old/used oil with your old motor oil in an environmentally SAFE manner.

3- Add the oil until it fills the snout to the bottom of the threads. It will take almost two bottles. Be careful to NOT overfill!

4- Screw the plug back in and do not over torque. 8-12 ft/lbs is more than enough!

5- After driving around for a day or so, check the oil level while the car is on a level surface. It's also a good idea to check the level of your supercharger snout at every oil change
