We do have Penn Synth Blend 15-40 that I was thinking about trying on my next change since I'm due. We also have Rotela Full Synth 5-40 that a lot of diesel customers swear by.
Really and truly though, as long as your consistent with changing the oil AND oil filter...your good no matter what you use.
