I ahve done a search for SC oils, and have seen many suggestions such as turbine oil, gm alternatives, etc.. I am wondering if anyone has an alternate that is easily acquired. I read that synthetic 5w30 can be used but only saw limited use in the search I performed. Is this a viable alternative? Thanks in advance

Is this a viable alternative?

As you can see from your search, not many people would reccomend putting motor oil in the supercharger. Just because people have done it doesn't mean it's working. The GM oil is pretty cheap and if you don't want to use it just go to any regional airport and buy a quart of BP2380 turbine oil.

It only takes about 8 oz. to fill the supercharger.

I am getting some oil from work that we use in our blower systems. These blowers draw plastic resin from our Silos 24/7. we use about 700,000lbs of resin a day, and tehse blowers generate the vacuum that conveys it from rail car to silo, and then from silos to 60 plus molding machines all day and night. It is synthetic and should be more than up to the task. Thanks for input

Better double check on the viscosity of that oil, temperature ranges etc..... you could be getting yourself into problems.

Just because its good there doesn't mean it will work good in our blowers considering the heat build up, rpm fluctuations and so on that the m90 sees in our cars, and those blowers you have at your work...... (I wonder if there is any plastic parts in those blowers)

I've got a '94 SC. How do I check the SC oil?

Also, I've got 100K on it. Should I actually empty it and change it?

Take care.

trust me if it works on our blowers at work it will work in a supercharger. These things are all metal, look like a large paxton s/c. they run constantly, 24/7. they convey 3/4's of a million pounds of plastic pellets everyday. I work for the #1 housewares producer in the US and we are on our sixth plant. If the oil in these blowers didn't work it wouldn't be used. To check your s/c oil ther is a fill plug to the right of your snout(if standing in front of your car) I think it takesa a 3/8" allen but some might be torx.

So your making the assumption that just because the gear box oil used in your employer's industrial vacuum system can run 24/7, it must be as good or better than what Eaton reccomends for your supercharger ?

That makes about as much sense as filling it with axle grease :rolleyes: .

This is not a rash assumption, this is based on 1- the advice of my ase mechanic turned maintenance manager, 2- the fact that I know as a technical supervisor who works on this equipment that these blowers run much hotter, way more rpm's, and constantly which is not so on a car, and 3- I am pretty sure (but will double check) that the oil is one of the types reccomended in the search I did. Assuming that I would put no thought in this, or that I am one of the many "credit card" mechanics that abound on car related forums is silly and insulting. I know what these blowers at work do, and I know what the eaton on my car does. It is essentially the same as the folks who are using aircraft turbine oils, they are making the assumption based on the fact that the oil used goes through much more severe duty than their s/c's and that is the same thing I am considering.

Wrong...I'm one of those people using the aircraft turbine oil and have actually read the specifacations and determined that it exceeded Eatons requirements. I also know that one of the companies who provided ported SC blowers for several years (ESM) also used the same oil in all their high performance blowers. The only one making assumptions about the oil is you.

Please remember that you are the one who posted here asking about the supercharger oil. No need to be insulted just because I dissagree with you on how to properly determine if the oil is compatible.

BEEN USING " MOBIL ONE " 5-30 FOR 3 YEARS PLUS :eek: NO PROBLEM BUT I DON,T BEAT IT :confused: I STILL PUNCH TIME TO TIME,AND IT ALSO STOPPED MY SNOUT LEAK THAT,S WHY I STARTED TO USE IT :D BUT THE TURBINE OIL IS BETTER YET :p GET IT A THE AIRPORT BY THE QUART..ALSO USE ROYAL PURPLE 15-40 I N MOTOR :cool: CHANGE AT 10000 PLUS ,,,,,,,,,,,,,, AS YOU SEE, EVEN MOBIL ONE NOW IS SELLING LONGER MILEAGE OIL ALSO

I'm with Uncle Dave on this one. I also have read the manufactures data sheet on this oil. I use BP2380 in my blower too. Turbin oil maintains a low volatility when used in a closed chamber environment, AND it will do that at 20K RPM. Actually it will operate at speeds far greater than 20K rpm, but 20K rpm is about as fast as any "reasonably" sane person would spin an M90 (+15%).

Read about BP2380 here: http://store.yahoo.com/oilstore/bpturoil231q.html

Dave: Are you still spinning your blower at +18% ?

Mark,

That's way too slow...I'm at 23% and sometimes go to 26% at the track.

Go ahead and use the oil from work. When you need to replace your blower, look me up. I have a spare :rolleyes: I'm with Dave on this one. One of the things you have to consider is the flash point of the fluid. I did some comparisons on the Bp oil and the NYE oil before I purchased. NYE oil had some better numbers, but 32mil will run you $56.00. I figured this was a lot cheaper than a blower :D

You guys are nuts and/or making it way to hard. Go to GM and get some GTP oil. It is cheap, and always in stock.

David the oil he is speaking of will work it is used in "superchargers" and is a synthetic just like the stuff in our SC's. The blower he is refering to is a Roots blower.

One part # for this stuff is Aeon PD 28G24 and can be bought from Gardner Denver Blower Service.

No Comments now? I guess no-one wants to act like I haven't got a clue any longer, sure beats filling the case with axle grease huh?

No need for comment I already know what you are working with, I see blowers all the time. I work for a scale company that provides controls for air, auger, and impeller packers. Also in motion checkweighing systems. We work with lots of plastics companies, Katon Natie, Rapid industrial to name a few. Plus more products than you think are conveyed this way, so just about everybody has these blowers around.

I'm glad that your assumptions were proven to be correct. I'm just wondering why it took me questioning your judgement, before you did the research....huh ? I'm also wondering why any of what I have said in this thread has insulted you.

Some of the comments seemed smug, and I was planning on researching it fully was just waiting to get the name and #'s for the oil. But based on my knowledge from the 14 years I've been working with industrial equipment I was confident that this would work. I guess the impression I got was that since I don't work on cars for a living, or spend a fortune on my car I had no idea what I'm talking about. The only reason I went into plastics instead of auto mechanics out of High School was I didn't want to be under a car with winter road crap dripping on me(I grew up in New England). I guess I'm just trying to say :p I AINT NO DUMMY :p Sorry if I got pissy, Its been a long w/e at work
