Does GC meet GM 6094M spec?

[novadude]

This is the cold pumpability spec that GM requires on many new vehicles. Does anyone know if GC meets it?

Thanks!

I would assume so. Castrol GTX meets that spec so I can't see why GC wouldn't.

No, GC does not specifically meet that GM spec. Syntec 5w30 & 10w30 are the only Syntec grades that carry the GM 6094M spec.

It's probably because GC is geared toward the European crowd.

Read the label on the back of the GC bottle & you'll see what I mean.

I'm sure GC would pass the GM 6094M spec, but since no American cars (that I'm aware of) call for 0wXX oils, Castrol probably figured "Why bother with the GM spec?"

GM 6094M is a cold temperature pumping spec. The spec for the 0W grade is max 30,000 cP@ -40°C.

I don't know what the GC cold pump spec is, but Esso XD 0W-30 meets 6094M with 22,600 cP @-40C.

Here is the GC spec for Pump vis D4684 cP note: 0w @ -40C = 20900

6094M is for 10w-30 only I think. It's not a tought spec at all, EVERY single SL/GF-3 oil met it. It requires no more than like 50,000 Cp at -30C for cold pumping. Most GF-4 10w-30s are well below 20,000. I think it just makes it so Joe Bob doesn't fill his crankcase with 1980 10w-30, which would be near the pumping and cranking limits allowed by the API.

That spec is for 5W-30 too. The owners manual on my new Colorado specifies that you must use 5W-30, and it must meet that spec.

I suspected GC is fine, but figured I'd ask anyway.
