11th gen forum is crickets unless you have an FL5. Helps that a lot of 10th gen parts fit the 11th so when stuff gets announced here it mostly fits on the 11th.
When I look at the service report it always says 0W/20 Full Synthetic. It’s probably that black label one and not the ultimate full synthetic grey bottle. At the same time, wouldn’t surprise me if they call it full synthetic and it’s blended.
Is Pennzoil Ultra Plat 0w-20 better than OEM 0w-20? I bought a lifetime oil plan from my dealer for $695 and have been changing my oil there every 4K miles, but if Pennzoil is better I’ll probably bring them that and have them change it.
I would ask if they can send a replacement and send them a picture of the issue. They seem like a company that genuinely care about their products having spoken to them and working with them.
