Diesel Oil

I like the new Motorkote because it is difficult to find 10 qts first, for under $75 and next it is difficult to find full synthetic in the 15W40. I have been using Motorkote since its inception. I am a salesman for all Motorkote products. I talk it up at work and in my personal dealings.
