Does anyone know who manufactures the oil that GM use, or sell as their re-branded version ?

Good question, one I have wondered myself.
Don't quote me on this, but i'm sure I once read it was a Mobil sourced oil.
I too thought it my be Mobil, but I kept my mouth shut as I am not too sure if it was.
On my last service at the dealer in June it says they have used Shell Helix Plus on the invoice, I have a litre of it for topping up
So we're none the wiser
What, they gave you some LOL I had to buy my oil from the Shell garage !
the oil is by fuch oil which i believe is part of the silkolene group
So even if the sump is full, you can still have "fuch oil" in it.
