'94 Dodge Dakota, Crankcase Sludge

Q: I have a '94 Dodge Dakota truck 6 cylinder, 4 wheel drive. I change the oil every 3,000 miles but I have trouble with SLUDGE in the oil pan. This problem caused me drop the pan and clean it out twice already. What can I do to keep this sludge from building-up?

- Derrick F.

A: Any chance that you're a short trip driver? Short driving trips are really rough on the engine oil. I'm a great example of the problems related to short trip driving. I live just 5 miles from work, my vehicle's engine hardly warms up before I'm shutting it off. This type of driving is tough on oil. I change the oil in my vehicle every 2 months and if you do the math it is easy to figure that I have not driven 3000 miles. My wife on the other hand has no sludge problems with her vehicle. The only rest the oil gets is when she's home for the night. No problem with running the mileage out on an oil change for her vehicle. I would suggest good quality oil and base your oil change intervals on time and not mileage if you're having a sludge problem.
