This is my second oil analysis on a vehicle that I’ve owned since new; I welcome any comments. The vehicle is a 2002 Dodge Ram 2500HD Quad Cab with a Cummins 5.9 liter, 24 valve, turbo engine and auto tranny. The truck is driven about 50-50 stop & go and freeway. The truck is not used for towing or racing. During the first sample, a Fleetguard panel type air filter was used in the OEM air filter box. I changed air filters at the start of the second sample period to a Fleetguard , P/N #AH19004. This is a very large cylinder shaped paper filter that is attached to the air induction tube and sits on a metal heat shield. The oil filter used is a Donaldson ELF full flow with no bypass filtration.
The lab was Oil Analyzers Inc. and their analysis recommendation was no corrective action required, oil is suitable for continued use. Resample at next regular interval
Previous oil and filters were changed at 6 months and/or 7500 miles. My biggest concern is the iron @18; which is a 29% increase from the previous sample. Actually, most of the wear metals increased from the previous sample. The only explanation I can come up with, other than the oil used being different, is that the ambient temps were very hot during the sample period. At one time we had 42 consecutive days of 100° plus temps. I think that I will run the Amsoil AME to about 10k miles and then change it. A friend recently gave me 4 gallons of Mobil Delvac 1. I may try that when I change the oil next time.
