Well, I think we pretty much knew Mopar oil is just re-badged whatever manufacturer they have a contract with. PQIA tested Pennzoil Yellow Bottle (conventional) and the numbers are a match to the Mopar stuff. If you Google the Mopar oil part number, you'll land on a cross reference PDF file that shows what Mopar oil equals what Pennzoil oil.
As far as the Toyota oil, that IS their regular oil. My wife's Lexus ES350 is spec-ed for 0W-20 and a 10K mile OCI per Toyota and thats the oil the dealer uses. A little long of an OCI? Maybe, but its still under warranty so Ill pay the dealer 100.00 for an oil change once a year. If there is ever an issue, they can handle it. Once its out of warranty Ill probably go to a 2x/yr OCI (regardless of miles, because we only put 8-10K per year on the car), but I will still gladly use the genuine Toyota 0W-20 if I can get a decent deal on it.
