Write-Up: Changing Supercharger Oil

My definition of "mid" is behind the driver and in front of the rear axle.

Ohh, this is no ordinary corvair.....
What are the specs , hp, to , 1/4 miles.....
BTW nice set-up. Lots of work there....

To be called mid engine, the engine has to be in front of the rear axle....

Which makes this car mid-engined... The friggin' thing is in the back seat for chrisakes!

I never liked the ordinary vair engine so this is my way of having a great looking classic with better then average performance of a like equipped ordinary (and now common place) 60s Camero .

1/4 mile in 13 sec
aprox 375 hp
Handles great, I won a autocross with it.
I usually drive this car on the weekends.

No back seat drivers in my car!

Not unless they're wearing asbestos boxers!

Funny!

I still have not changed back to supercharger oil, I have flushed with mobile one 4 times and bought the right stuff but not gotten to it yet , and now theres a possible sale pending on a SC 03 GP theft recovery with a bad title for perhaps 600 bux, so I am unsure what im doing until i score the GP

Hope you end up getting the GP.
Do you plan on parting it out?

Yes it will be parted out of I get it, do those trannys fit our rivs?

I don't know.
Maybe the deekster can tell you. Ha has some experience with the GP's.
I thought I remember him telling us that those transmissions don't have the casted webbing necessary to support our transmissions and they will crack after install.

But that was a story he told a while ago and I can't remember the year and model transmission. DON'T take my word for it.

I am likely to pull the driveline and stuff it under the bench until needed, that's the best way to prevent breakdowns ... Aint it?

Why would acquiring the 03 GP have anything to do with putting the correct fluid in your SC.
I don't understand. I was thought I understood that the Grand Prix's didn't get the GEN V SC until 2004. That's the only reason I could figure out why you weren't going to continue to freshen up your existing L67.

The attempt to flush the goo from my SC was only to prolong its life, the snout bearing is growling and produced a fine silver content to the oil.

I have been searching for a cheap junk yard snout all this time and now a entire 03 GP has possibly popped into my life, I can swap the snout, put a new coupler and use my already purchased SC oil to seal the deal, save the engine/trans, part out the rest .

My intent is only to maintain the riv, not upgrade to a GEN V (or anything else)unless stuff falls into my lap.
Believe me I was holding my breath while popping the hood hoping to see it had a V , at least it had a SC was my next thought.

Does any one know what size or kind of wrench it takes to remove the supercharger plug on a 1996 Riv? I have changed it before and I thougut I used an allen wrench but it does not work this time. Any help would be appreciated. Thanks, Tom

It does take an Allen Wrench. Don't remember the exact size, but if you have a kit of them you should find the size to fit it. If I remember correctly that is an american size as the SC is made by Eaton here in the good Ol US of A.

If your wrench's aren't fitting, you may have buggered up the hex a bit and may have to try a Metric to get it to fit and come out. Then I would suggest replacing with a new one from one of the vendors or GM, because next time you try it you may have to use an easy out tool.

Good Luck with it.
Rick

3/16 Allen fits. If you have a 5 mm, it might work.

How often are you guys changing the oil in the SC, by the way.

I did mine shortly after buying the car and haven't done it since. I'm sure it's due, I have about 40K miles on it since last change.

I figure I should add to the list of things to do at every 30k miles, probably with every Trans Fluid change would be a good point to do it.

What do you think.?

I change SC oil when I do the trans fluid and plugs every 25k miles. I check the level about every other oil change.

I haven't checked the SC oil level because I haven't seen any leaks or weepage.

Hell, I haven't checked under the back seat to get a look at my battery in over 3 years, now that I think about it.

Whenever I have done work under the hood that requires disconnecting the battery, I just disconnect the connection under the hood and tape off the battery cable coming from the back of the car. Has worked for me.
I guess that is born from having a bad back and not wanting to crouch in the back seat area in an uncomfortable position and jerk the seat bottom up. The last time I did that I regretted it. This is the simple stuff I have to pay someone to do for me nowadays. But I keep forgetting about the battery.

Admit it, you're like me and just too lazy to clean off the back seat and lift the seat up. Just like the toilet seat.

Thanks Rick, It is a 3/16 allen wrench. There was a bunch of dirt and debri way down inside the opening of the fill plug so thats why I couldn't get the allen wrench in there. I called and ordered a new fill plug because this one is getting pretty sloppy inside. It will be here Saturday. Thanks Again, Tom

There is no definitive answer. According to Eaton," The oil used in our superchargers is classified. We have never used whale oil. Whale oil is like Ivory,it is not a tradable commodity"
Me: "My 1995 GM service manual,on the M62, offers 5w30 oil as a substitute for GM oil"
Eaton: "We cannot answer why GM allows 5w30 as a substitute.Our oil is a NYE 605.It is a gear oil"
Me: "Why doesn't GM offer 5w30 as a substitute oil in the M90 S/C"
Eaton: "We cannot answer why GM does not allow 5W30 oil as a substitute"

Sounds like a whole lotta whale shit to me. Ill continue using my PRO recommended blend of 5W30 syn oil with Lucas oil stabilizer.
Eaton can shove their stinky NYE 605 oil right back up their arses.

Another product recommended by Supercharger USA .com for their rebuilds.
The Redline stuff is used for high HP Blowers.
PSEsuperchargers.com,out of oklahoma,A S/C rebuilding company, only uses Mobil 15w50 oil.period.
Not one company i called use the GM oil.They go so far as to recommend it,but when asked if they use GM oil,the answer is no.Lotsa cooks in the kitchen but everybody is using different ingredients. Not following the recipe at all!
Update: According to a source,One of the ingredients in the GM oil is a Synthetic Castor bean oil. It just sounds more and more like Gm Wants to scare the consumer into buying Gm oil exclusively by engineering an Exotic S/C oil.
The performance S/C repair and rebuild industry would go out of business overnight if their superchargers burned up for failing to use the Eaton/GM recommended oil.

So wait.... Is Eaton saying that lightweight shockproof gear oil is good for their M90s? And if so... how much less $$$$ we talking about?

Wait... I just looked it up and you can get a 1 quart bottle of this stuff for about $11 on Amazon and that = 32 ounces. Last I checked, we put a little over 6 ounces in on a SC fluid change. If those bottles cost roughly the same amount for only 4 ounces, this is a pretty damn good deal.

Can anyone confirm? Not that I need oil now, just curious.

Well, the S/C oil is made of this......(I have a bottle)

Fatty Acids, C5-10, esters with dipentaerythritol
Phosphoric acid (1, 1-dimethylethy)
phenyl diphenyl ester

I suppose if we find an oil made up of the same shit we'd be ok.

I'm not a chemist, so I have no idea wtf any of that is except Fatty Acids and Phosphoric acid.
