I guarantee you its better than that ecore PF48E they say mine should run. For warranty maintenance purposes I'm running the Mobil 1 M1-113. Do the specs of the 64 match up okay with everything insofar as running on the Silverado are concerned? Is the bypass on that thing on the top of the filter or at the inlet?
FWIW, according to Fram's competitor cross reference, both the pf48 and pf64 cross to the same Fram ph10060.
