[Vwdiesel] Lubrication for beginners--- ( what really is DINO ? )

[pmdolan at sasktel.net]

Aircraft piston engines use dino oil because they are extremely low stress, antiquated technology and not a very big market.  The liability risks are huge, and the reward miniscule, so nobody really give a darn.  There isn't a full synth out there that wouldn't out-perform AD oils by several orders of magnitude in that application.

VERY FEW oil brands own their own base oil refineries.  In fact, each refinery is built to suit the crude from the area.  There are no "good loads and bad loads".  Of the mere handful of base oil refineries (under a dozen in North America) come hundreds of brands.  For instance, Castrol, #2 in the US, has no refining capacity at all.
