Has anyone tryed this oil? http://www.conklin.com/pg.asp?p=6

I heard a couple people singing its praises about using it in thier DMAX and thier farm tractors. One claimed that he had use the oil, drained the engine oil on an old tractor and let it run for more than 30 minutes without any problems. Sounded like a sales pitch to me.

Anyway. I would love to know what people here think of this

I used to use Conklin parasynthetic. I think it is really good stuff, it has moly in it. My dealer died and I ended up switching to Amsoil, but I think they have excellent products.
