Probably the same thing in the GM bottles.
Hate to know what you paid for it.
If you switch your engine oil over to synthetic, you can buy the 5+ quart jug of Mobil 1 Synthetic oil and filter, do your oil change and you will have enough oil left over to change the oil in the */c. And yes, the Mobil 1 is authorized by GM to be used in the supercharger.
