GM Supercharger fluid

[T-Keith]

This is a bottle of supercharger fluid meant for eaton superchargers. It's also recommended in some aftermarket applications. It's supposedly foams to lubricate the bearings. Some people have tried to cheap out and use synthetic engine oil or gear lube, which almost always leads to a destroyed SC. GM recommends checking and topping off every 30,000, but never changing it. Worse still most dealers and service stations don't even know about it, so this stuff takes some abuse. It also stinks very bad after use, must be the fatty acids? It's about $8 for 4 oz.

Ingredients per the bottle:

Fatty acids, C5-10, esters with dipentaerythritol-phosphoric acid, (1,1-dimenthylethy)phenyl CAS-70983-72-1
diphenyl ester CAS-56803-37-3

Someone needs to prove that foaming statement because that is absolutely ridiculous. Foam is not a very good lubricant!!

Plus I think it only lubes the gear drive. The bearings are probably sealed? Don't think so? Then what lubes the bearings on the other end?

Not sure what the diphenyl ester is. The rest is a Polyol ester.

I haven't heard anything about foaming, i have just heard about a "misting" lubrication. That the mist caused by the churning lubricates.

But i think everything that goes on in the snout is a mystery to us.

ferb!

guys this stuff is basically turbine oil. We use regular turbine oil when we rebuild an eaton supercharger for a tbird supercoupe. Its the same thing.

GM and ford both sell it in little bottles, but GM is much cheaper.

Its a good idea to change it every couple years, its cheap and easy to do. I just suck it out with a little vacuume hose through the peekhole.

It lubes the front bearings and the sprockets I believe the rear bearings are lubricated with a special grease.

I meant to say misting, not foaming, sorry.

So the smell is just there to scare children and make women scream?

It really does smell like old whale oil, which is why i always thought it had "different" properties than a conventional turbine oil.
