Rotella 15w40 vs Rotella 15w40 Full Synthetic
Simple questions: Which one is better for the 6.9 IDI ? Any advantage of using one over the other ? Anyone use the Rotella of either "blend" ? Reason for asking is that I'm due for an oil change and I can get a gallon of Rotella 15w40 for $12.50. The Synthetic is obviously a little more...- raeasler
