After a week of Magnatec,PPHM definitely for the win!! The Magnatec isn’t as “smooth” as the PPHM. Everything I’ve used PP or PPHM in just runs impeccably smooth and quiet. UOA’s are always flawless as well!! Pennzoil definitely has “something” in their formula that just seems to work.
You need to give an oil 1500 miles to strip off the old stuff and fully lay down it's new add pack IMO. Then, and only then, will you start to know how it's going to run for you.
