2002 Dodge Dakota QC 4x4
EQUIPMENT MAKE: Dodge
EQUIPMENT MODEL: 4.7L V-8
FUEL TYPE: Gasoline (Unleaded)
OIL LAB: Oil Analyzers (left 4 columns)/DysonAnalysis (right most column)
Overall, I thought the wear numbers looked pretty good based on the miles on the oil, but Terry thinks there is plenty of room for improvement. I'm disappointed in Mobil 1 EP as others have mentioned as well. I'm not certain, but I think that was the second consecutive time I used Mobil 1 EP.

Note there is a gap in the history during a period of time when I didn't have oil analaysis done. The oil was in use for approximately 1 year, although it obviously should have been replaced well before then based on the analysis. The air filter was replaced about the same time as the last oil change. Driving is 60/40 highway/city.
According to this report, a TBN less than 3.0 is considered too low. The oxidation and nitration levels are very high.
I will not be using Mobil 1 EP again after the next oil change, and will be changing a number of things based on Terry's recommendations.
Overall, I thought the wear numbers looked pretty good based on the miles on the oil, but Terry thinks there is plenty of room for improvement. I'm disappointed in Mobil 1 EP as others have mentioned as well. I'm not certain, but I think that was the second consecutive time I used Mobil 1 EP.
