Pennzoil is great oil, whether it is the Dino or Synthetic, the 100's, if not 1000's of UOA's on bob is the oil guy .com (www.bobistheoilguy.com
) proves it beyond a reasonable doubt.
I am not a big fan of Royal Purple, not saying it is a bad oil, but there is nothing "Superior" to it at all, at least nothing that comes remotely close to the price they charge for it!
If you really want to learn about oils, greases, ATF fluid, or anything else oil/lube related, and a bunch of of things, check out the site. It is a site just like this, members join and show their UOA's (used oil analysis) that they have had done at a lab of their choice.
tks, already a member of bob is the oil guy. having trouble finding ultra and a replacement that is equal to ultra. been using mobil one for over 30 years, just irks me they didn't do the chrysler cert, and ultra is as good maybe better. bobs guys say to use the top shelf amsoil, but i am not doing 25000 oci for warranty purposes.
