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 expensive.
Not sure how quickly the synthetic turns black. Again I am.guessing that it would stay cleaner longer but in have no idea as I have ZERO experience with the regular vs synthetics in the diesels.
