I don't know if the oil is still good or not. I used to pull oil samples every time I did an oil change. My local CAT dealer once told me that they would work with me to find the optimum time to change my oil. They told me that I should be able to get at least 25,000 miles on an oil change. I probably should have followed through with them. Old habits are hard to change. One way I have found to determine that it is past time to change the oil is by monitoring oil pressure. If the pressure drops below a certain point then it is probably time to change the oil. While not scientific, I have had this happen on one truck. It is probably as important or more important to change the filter as the oil. Filters can become clogged and that can impede oil flow. In this instance, I had a couple of different drivers in that particular truck and the oil change interval was missed. The truck was about 1,000 miles from home. The oil pressure dropped dramatically. The driver thought the engine was about to blow. I had him change the oil and the pressure came back up with no problems since. It is a good idea for anyone running trucks to do an oil analysis from time to time. It can give you a heads up on a potential problem, before something dramatic happens. It is cheap insurance.

Seems to me if you buy a truck with one of these def systems, an APU is almost a necessity, as well as doing a PM every 8-10,000 miles...
