Thanks for the feedback. Do any of you have this sticker in your engine compartment?

Thanks for sharing. Seems the car did not like the Castrol 0w40 if I read it right. Other than higher Boron, it seems the Pennzoil did a good job. I wonder if the results would be different after using the thinner 0w30 oil in the summer.Have you seen this see UOA of this exact oil (and others) for a GOLF R?
