I do not know. I am willing to pay extra because the Penzoil UP has a tremendous reputation among the wizards of the interweb... particularly in the fuzzy (to me) realm of low-speed detonation.Think the Pennzoil Ultra Platinum is better than the Motorcraft Full Synthetic?
I may run a short OCI this cycle and send a sample to Blackstone - then run a 5k OCI and send another sample to see where it settles out on PuP.
Is PuP better than Motorcraft full syn? As I have already been kindly reminded of my knowledge limits in this thread, I don't posses the definitive knowledge to say.
