This is my work truck so it goes to Jiffy Lube where I watch them do the work. They like to tell me the conventional Pennzoil is only good for 3k miles so I had it analyzed. Truck has 15k total, oil was in use for 5023 miles.

Water (%) Coolant No Physical Tests
Viscosity (cSt 100C) 8.3
Physical / Chemical
Base Number (mgKOH/g) 3.1
DIAGNOSIS All wear levels appear within acceptable limits for first sample. Silicon level (dirt/sealant material) satisfactory. Water content acceptable. Viscosity within specified operating range. Action: As oil and filter(s) already changed, resample at next recommended interval to monitor and establish wear trend.
