2023 GMC 1500 Denali ultimate 6.2L 20k miles
in service 5500 miles
grandfather’s truck that i convinced to change over to 5w-30 after he heard some of the fleet trucks (1500 5.3’s) and the difference in valvetrain chatter
out/off: 8 quarts Mobil 1 EP 0w-20 and Fram Titanium FS10575
in/on: 8 quarts HPL PCEO 5w-30 with Fram Endurance FE10575
filter is wavy but no tears. much happier now that it has an Endurance in its place. i chose to go straight to HPL as i have done all maintenance on this truck with Mobil 1 EP 0w-20 changed at 6k miles since new. dropped factory fill at roughly 1500 miles as i do with any new vehicle. i figured engine is clean enough to go straight to HPL PCEO.
