I have a 2011 Ram 2500 with the 6.7 Cummins that I bought new last August. The truck just turned 5,000 miles. When it was at 2,900 miles, the oil change indicator message came on.
The oil was black as coal, so I went ahead and changed it because I wanted to put Rotella in it. Either before this time or shortly after, the engine malfunction light came on, so I took it to the dealership and was told it was a 02 sensor so they changed it out.
About 2 weeks ago, the light came back on, and again, it showed up as an O2 sensor, but the tech just cleared the code and didn't change out the sensor. Now, at 4,930 miles, the oil change indicator message came on, and again, the oil is black as coal. I know diesel engines will blacken the oil, but I never let the truck idle. If I park, it's shut off. On cold mornings, I start it, and run the engine up to 1,000 rpms for about 5 minutes. I drive about 8 miles to work on the highway and back home.
Also, there is a mix of highway/city driving but not long trips. I know this shortens the life of the oil, but 2,000 miles? We run our big trucks 25,000 miles between services with Rotella so even under the conditions I drive, one would think I could get 5,000 miles out of an oil change.
Today I took it back to the dealership and spoke to the tech on the issue, and he showed me a very vague paragraph from Dodge on the engine oil change interval. It said max 7,500 to 12,000 miles, but shorter depending on the type of service. Anyone have any insight on this?
Thanks in advance!!
