What Is The Makeup Of Gm Supercharger Oil

i belive then ive been using information technology for most 500 miles now and no problems

BP 2380 Turbine Oil

I bought some BP 2380 Turbine Oil online (forget the URL), for nigh $7.l/qt. It was something like oilstore.something. I think that Dave. North. knows the URL. Information technology's what EMS puts in their blowers.

Ive used the BP 2380 with excellent results. If you accept an airport close by you can get information technology in that location for between $7.00 and $10.00 a quart.

The guys at the GM dealership... he said they were even the aforementioned manufacturer.

Oh god... here we go again... the manufacturer of the Supercharger is Eaton.. the manufacturer of the oil for the Eaton supercharger is whomever.. Ford'south oil costs more than, GM'due south costs less and if anyone wants to pour molassas in the SC case and swear up and downwards that its the same as Ford or GM fluid, allow them practise then. I'thou done with it.

Well is there a problem with the BP 2380 that nosotros need to be enlightened of. There have been more than a few peaple here that accept recommened information technology..

I utilise the GM fluid since information technology's designed for a Eaton M90. It costs around $10 -$13 for a complete fill. Why everyone would try and save a few dollars on something that needs changing effectually every 50,000 miles is beyond me.
In that location are a lot of better places to save a few bucks on the SC, and in my opinion this ain't one of them.

Couldn't have said it improve myself! People spend thousands of dollars on blowers and and so try to relieve a measly few dollars on the lubricant

Lets look at some statistics:

NYE Constructed Oil 605
FORD: ESE-M99C115-A
GM: 12345982

Kinematic Viscosity (cSt (mm2/s)):
100c = 8.7
40c = 54
-40c = 45,063

BP 2380 Turbine Oil / SHELL Turbine Oil 500

Kinematic Viscosity (cSt (mm2/s)):
100c = five.17
40c = 25
-40c = 9,000

If anything, SHELL Turbine Oil 750 (or equivalent) should be used every bit a substitute, not 500:

Kinematic Viscosity (cSt (mm2/southward)):
100c = seven.47
40c = 32
-40c = ten,140

The simply stats I couldn't notice on these turbine oils is their "Coefficient of thermal expansion". Because how pocket-size the space is in the SC nose, you sure don't want annihilation that expands much when warmed!

NYE Synthetic Oil 605:
Coefficient of thermal expansion (cc/cc/degrees c) = 0.0008

Kinematic viscosity is important when it comes to loads. Let me quote a section from a newspaper written on this:

Oils that yield a viscosity of about three mm2/s had insufficient load carrying ability to support and transmit loftier gear loads. Therefore, to these oils material thickeners were added (complex esters), which gave the required degree of load carrying power and raised the final viscosity to almost 7.5 mm2/s @ 100c.

From this i tin can conclude that kinematic viscosity is important, and too Turbine Oils (except the 750) don't measure upwards to the Ford/GM stuff.

Hey, people tin practice what they want, merely I'm with Jerry and others on this: the money saved is diddly-squat and the potential damage could be very costly.

Any idea how much a jet engine or turbine prop
engine costs?

No, just it'southward probably safety to assume it's a hell of a lot more than than an supercharger. I don't encounter the relevance to this topic though...

A helicopter'due south turbine engine spins at approx. 55,000 RPM'due south. A M90 spins at what, 15,000? Are you trying to say that a M90's internals are more precise than a turbine engine?

Again, no. I'm not claiming anything well-nigh the engineering science specs of the SC compared to a turbine engine.

I sympathise your specs that y'all posted, but are yous going to tell me that M90 will last forever if you use GM or Ford fluids only?

Well, nada lasts forever. I practice believe it will last longer with fluid(s) designed for this application.

Just put, BP2380, which is British by the way, is a fine culling to Ford or GM oils, and yes information technology is cheaper. Geesh. It'southward just supercharger oil for crying out loud!

Lets simply say I'yard skeptical about this claim.

We all know the oil is at that place to course a layer over surfaces so that there is no directly metallic-to-metal contact. Straight contact leads to worn out components.

1 of the failure modes of a lubricant is viscosity breakdown. From what I see in the data, BP 2380 is a thinner constructed oil than the NYE 605. If we have some bug with the OEM stuff now, do you think replacing it with a thinner oil is going to be OK?

Then there'due south the "coefficient of thermal expansion" requirements. Turbine engines are much similar our engines... whether or not the oil expands in this situation is probably not important at all. Our SCs are a tightly bars space and I see the potential for this turbine oil being forced out past the snout seal when it gets hot.

These are just some of my thoughts on the subject... people tin can do what they want. I'one thousand certain well-nigh are reading this and drawing their ain conclusions from the word so far (every bit it should exist).
