Oriley has it for $25 for a 2 gallon jug. It claims to pass all kinds of diesel specs but theres no api donut. Actully it says "recomended" for and lists several diesel specs. The lack of the donut scared me away.

Years ago I did a VOA on the Mystic 15w50..I thought I had posted it here on BITOG and will look for it. As I recall is was a pretty Plain Jane oil. Nothing special.

Even the name mystic is scary for an engine oil.

One of our local farm stores (Rural King) carries it, as well the 10W30 and 15W40 HDEO. At a much lower price than $25 IIRC.. in the neighborhood of $18.50. Too thick for my taste but I did buy some 10W30 for a neighbor's small tractor a while back. Decent specs for the money.
