FAQ: Supercharger Oil (M62 & M90)

i dunno if its just me...but why is the SC oil red? it looks like clear bottle cuz u can see the air bubble in the front. it looks like its clearly red...mine was clear.

That oil should only be for '95 superchargers keep in mind - '96 and newer require a different oil.

maybe its maple syrup?

Mrs. butterworths actually

first off sorry if this is not thread worthy, i wasn't sure if i should've just posted in the write up or make a new thread...

anyways, long story short;
when i was changing my supercharger oil, like an idiot i got a piece of straw stuck up in there. it happened right when i was almost done putting in the rest of the new oil. i tried saving it but it was a wrap. i couldn't possibly get it back.

its a McDonalds straw(if that matters lol) and its about 1 1/2 - 2 inches long.

i said oh well and gave up on trying to get it out, filled up with the new oil and called it a day.

am i gonna have a problem?

yes!

what would happen?
and
what could/should i do? i don't think i'll possibly be able to take it out

i would take it out. the S/C gets hot,if that straw melts into the bearings your S/C is cooked! it wouldn't even have to melt,leaving it in there makes no sense whatsoever. its a piece of cake to open up the S/C. do a search and you'll find write ups on how to remove the S/C. its not that difficult.get a friend to help.

Since this is in series 2, I'm assuming you have a 96+ engine, and the m90.

Refer to :

for taking the snout off and retrieving the offending bit of plastic.

The SC can stay on car.

I'd remove it ASAP. Even a straw can jam the gears in there, shattering the coupler.

i'm a freakin noob when it comes to workin on cars tho. only thing i do on my own is change oil. -_-

but hmm thanks i'm on it

Well, read up and consider yourself a mechanic for the few hours it may take you to correct the problem, it's not difficult to remove the snout, clean out the straw and re-assemble.

Plenty of step by step instructions on here and always someone to answer a question or 2, if it's not already been covered in the write up.

Don't ignore the straw in the SC snout area or it may cost you more than you want to pay someone else to do it.

Or just print out the instructions and pay a local mechanic to do it for you. most aren't 100% familiar with these SC's, but if you have the instructions from here it will be a breeze for a regular wrench.
Just get him some more SC fluid and the correct sealant for it. Don't use RTV to seal it up.

oh yeah.. i forgot to mention; i had already drove the car!!! i changed the supercharger oil when the engine was cold, then since i gave up on the straw, which i somewhat forgot about, i drove it around the block then later changed the engine oil/filter.

so u think its already melted up? what should i do now instead?

AS has already been said, remove the SC snout per the instructions, inspect the insides and clean it out and replace the oil. You don't want it contaminated with plastic, even if it has melted.

Or you could add fries and a coke to it. j/k

Straws are made of polypropylene, which melts at about 260ºF. In the summer, I'd guess the oil in the blower will get warm enough to soften the straw at least enough to grind it up real good. I'd try using a siphon pump to see if there is any debris in the oil. If you see any, suck out the oil until no more pieces are seen. If you don't see any pieces, it's either dissolved, or lodged somewhere in the reservoir. That's when I'd take it apart to see. But don't be surprised if you never find any evidence of that straw!

I'll retract my statement and agree with AA on this. I guess I could have over reacted and would probably do as he say's.
Hell, it wasn't much of a piece to start with.

i still think the fries and coke are a great idea.....as for the straw? we dont need no stinkin straws

As we've seen, I believe Robo meant S/C snout... and I agree that it should be removed, cleaned and re-oiled.

In fact, this would be a good opportunity to put a new coupler in there as well - they're all getting hard at this point...

lol thanks for the replies.

anyways, i kinda wasted my first post. i figured my first post should be in the welcome board for my introduction but might as well do it here. and maybe re-post over there when i get some pics... sooooooo

hello! just bought a 1998 Riviera with 76K original miles, which is in overall great condition. a few minor cosmetic issues, and so far no performance issues... the irony..
its silver or light gray, not sure of the exact color. i looked at the parts label but couldn't really make out which number or code was for the color? anyways it has all the options with the exception of moonroof

i've been looking for a good condition Riv now for prolly 1-2 years. and i'm happy i waited and got this one. right before i bought it, i came across this forum, and have been checking it out frequently. its funny because i used to always go on cardomain to check out Rivs, and now i see alot of those people are over here lol

alot of the things i want to do first are cosmetic wise. as i learn more about performance i'm sure i'll do upgrading. the first thing one of my friends told me when he saw my car was "get an s/c pulley and an intake" lol i don't even know.. but i'm sure i'll learn soon enough

I agree with Aaron.

I probably wouldn't be concerned. It's not as if you dropped a screw into it.
I'd certainly try to get it out by changing the fluid again first though.

Don't listen to your friend, unless you want to detonate the engine to death so soon.

Do more reading on the the progression of what's needed before you even THINK about dropping your SC Pulley size.

^lol thanks yeah i know, i always read up and learn as much as i can before i do anything. i've been lurking on this site for awhile now and i definitely already been thru some of those write ups and faqs relating to that

The FAQ for modding an L67(your engine), is honestly pretty complete on this site. I like to think of this site as all the "real" info, less the crap, compared to other 3800 sites. Check out the FAQ section, do a few searches, and you will be well on your way...

another question;
my check oil level light keeps showing up. i just changed the oil about 3days ago. if it matters, i used a Delco PF-52 filter and regular Pennzoil 10W-30 oil. I put 4.5quarts in and the oil level is fine, dipstick says it's on full. i've been driving it regularly ever since, and the light still stays on. what's the problem?

If you're checking the dipstick on level ground and getting a full mark, it's either the sensor or the wiring.
This sensor works the opposite way of most, meaning that it breaks the circuit when the oil is low,
rather than grounding the circuit and lighting the bulb... So, the first thing to do is check the connector to
see if is loose, or if any wires down there are damaged. Fortunately, these sensors are cheap - they
redesigned them a couple years before your car was built, from over $100 down to about $20.

( Speaking of which, please fill out your Signature line with your car info,
so we don't have to go looking for it when trying to answer a new question... )

I changed the SC oil on my fiancée's riv this week. After pumping out the old, black oil I put in the 2 bottles of what I assumed was supercharger oil. It turns out the 2nd bottle I put in was limited slip additive. I had purchased both bottles at the dealership at the same time. The bottles are pretty much identical and must have been mixed up on the shelf. I should have read them both AT the dealership and before putting them in, but at least I caught it before running the car. Pumped it all back out, but didn't have enough oil to fill the snout back up.

I called the dealership back and asked them if they had another bottle of SC oil. They said they had one left. When I showed up, I asked the guy for a bottle and he handed me the lone bottle from the shelf. It turns out it was limited slip additive (they only had 1 bottle), AGAIN. They had about 12 bottles of SC oil.
