f5fstop, thank you for the great information. Simply awesome. So I just grabbed one of the quarts i used in the garage and here's what is says about meeting requirements. Keep in mind it is Pennzoil Platinum Protection full synthetic 5W30.
"Meets or exceeds requirements of ILSAC GF-4, API SM and previous API standards, GM 4718M and other GM, Ford and Chrysler service and factory fill requirements."
So I assume that it's ok to run. I ran the original oil in the H3 (from the factory) for 3K miles and then had the dealer change it. They used synthetic. So I just changed it for the second time last night (plan to run it at least 5K miles or use the oil change monitor) with the Pennzoil.
What are your thoughts?
