This is my first 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. A Fleetguard panel type air filter was used in the OEM air filter box. This filter differs from the Mopar version in that it doesn’t have the foam pre-filter on the bottom. The oil filter used is a Donaldson ELF full flow with no bypass filtration. Ambient temperature ranged from the mid 20’s to 100 degrees F during the sample period.
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 used was Amsoil HD Diesel & Marine 15w-40 (AME). Previous oil and filters were changed at 6 months and/or 7500 miles. My concerns are the iron @14; the silicon @3 and the copper @7. These numbers are for 4979 miles; I was hoping to go 10k miles on the oil but it looks like I will have to settle for 7500k. My primary reason for trying this oil was to see if my fuel mileage would improve any; unfortunately it didn’t improve enough to justify the cost of the oil.
