The systems they have are known in the large truck market. But what the heck. I'll take a quote, just to see if you are cheaper then the last one I got.
I took a trip to the local Wallie's and they had it back on the shelf here too. Just no shelf tag. Makes me wonder about the managment there.
I've had no issues running the Rotella syn. I actually like it more then the Mobil or Valvoline that I have used in the Cummins. I don't get any of the "smell" that some talk about and the engine does seem to run a little smoother as well. I can tell the difference is running the syn over the conventional when it comes to mileage. I get about 1-1.5 mpg better with the Rotella syn in the engine compared when I was running the conventional Rotella.
