So as it stands, the Z51 can use a PF64 or a Mobil-1 113 but not a UPF48R, correct?

The PF64 is a $6 paper filter, and the oil is a very-low-synthetic-content-blend worth all of $25-30 for the entire change.

If you're keeping long-term (past 75,000mi), I would encourage self oil changes with better oil (does not have to be M1, but any quality dexos1 synthetic passing the highest tests) and a better filter (M1-113, Napa Platinum, or similar).

That's quite a generous service, as they're not being reimbursed for that (unless the dealership has a good deal on the fluid, itself). They're only reimbursed for the factory part number stock cost.

It exceeds GM's requirements, and is an overall better filter than the ACDelco (non-R) equivalent.

About $13 a pop:

The first 20,000, or so, C6 Z06's, came from the factory with PF48 filters(as did my 2009 Z06). Never heard of a single one of those Z06's that had catastrophic engine failure due to using the run of the mill AC Delco filter, nor did GM ever send out a memo stating that Z06 owners should not use the PF48 filter or a replacement page for my owner's manual. The Z06 has a 100psi oil pressure gauge where as the LS2's and LS3's have a 80psi gauge. From what I've seen, the Z06 does run at a higher operating oil pressure vs the LS2/3.

Then, in the summer of 2008, when GM released the ZR1, they started installing the UPF48R filter(and the LS9 still had the same 100psi gauge as the Z06) on the ZR1. In the interest of standardization at Wixom, they started using the UPF48R on all their engines(LS7, LS9 and dry sump LS3's).

That said, I believe the Mobil1 M1-113 and the K&N HP-1017 filters are the best available and that is what I use. From what I've read, the UPF48R is the same oil filter as the Mobil1 M1-113 but the Mobil1 filter can be purchased at nearly any auto parts store whereas the ACDelco filter can be difficult to find. I see no sense in paying shipping on a UP48R filter when I can pickup a Mobi1 filter when I buy my oil.
