exactly as it says...your eaton superchager in the snout has its own oil and it needs to be changed, depending on the pulley size and the rpms you are turning. in order to change it. there is a black plug on the snout side of the supercharger with an allenkey just undo that and using a turkeybaster with a small piece of hose suck out as much as possible and replace it with the new oil. should take almost 2 bottles

 

damn i keep hearing diffrent things... i wish i could get a definitive answer

 

When I drained mine while porting & polishing it >> There was about 2 oz in it maybe 3!

 

I'm almost 100% sure that GM recommends changing it at 100,000 miles.

BUT, that's with the stock pulley as well! I think I might wanna change mine soon!

 

i never even heard of this

 

hmm where to pick it up local . is it gust gear oil?

 

not sure what kind of oil buts its pretty light and really refined. GM says 100000/miles but if i remember correctly eaton reccomends sooner.

 

Now you have.

Pick it up at the dealership... or from one of the many vendors that stock it (i recommend Crateenginedepot.com)

Don't just put gear oil in there. I'm sure you can... but don't.

 

Are You New

 

it's $8/bottle at the dealer.

 

does anyone have a how to on this with pic's?

 

i thought the supercharger was fill for life

 

no...i believe 100,000 kms on stock s/c.... and yes, that s/c oil does exist...i bought some from my local gm dealership for 5 bucks a bottle.

 

now that I think about I have notice that mine was getting louder before the head lifted maybe I should look into changing it before I put it back on.

 

superchargers have moving parts. obviously they require oil. Obviously oil wears out after a while, and if you run a smaller pulley the internal supercharger parts are working alot faster hence the oil will wear out alot quicker. So it's a good idea if you have a smaller pulley to change it at probably 25,000 - 40,000 miles. IMO

 

it takes 6 oz, you can buy from gm or buy a quart of 15w50 fully synthetic mobil 1 at an auto parts store... this is what stiegimeier does when they do rebuilds... ive asked them and they recommended every 30 to keep it fresh and clean and also regrease the bearings in the housing

i just recently had to take mine apart if you guys need any help or want to see pics of the inside parts
btw, if the supercharger is not taken care of properly things will start to go bad(really only small pulley applications)
bearings will need to be replaced or rotors will start to wear out and the the sc will sound like a bucket of bolts.... happend to me

 

this is good to know

Pm me with the pics please.

 

ill post some and pm you... may make a tread if there is not one already

 

when i had the sc on my car i'd change the oil with every oil change.

 

Can the dealership do this for you??

 

yup with small pullies it burns black pretty quick

im sure they will charge quite a bit for the labor... if you can, i would do it your self. it takes about an hour... dealers charge around 90 per hour

 

Whats the recommended intervals you should change the oil on it with smaller pulleys?
