The thread is about oil filters, not oil. I wasn't aware Royal Purple was doing filters now. The only filters I would consider are the factory PF64 and the Mobil 1 (what I use).After spending over two hours reading over info on three different sites on the web, I have deceided to use one of these 3: Mobile 1, Royal Purple, or Amsoil.
Dude, you need to go to YouTube and search for "Fram the Orange Can of Death".I used a Fram filter when I did my oil change and on the box it said something about use with full synthetic oil.
For the C7, used the GM recommended AC PF-64. Bought mine from the local Chevy dealer since I could not find a PF-64 in a local auto store. I asked if I could get one "free" since I was not using the free oil change service (expecting a no!) Since the parts department is run separately the best they could do was a 33% discount! Believe I’ll use an aftermarket brand next time or buy a few on the net to cover shipping. If you’d like a 7 page picture PDF on a Z51 oil change look on this page of my website: netwelding.com/Reports_Vette_Info.htmWhat brand of oil filter are you using or plan to use on your C-7
