Well, it seems we now quasi-officially have two classes of forumners on this site - the effete elitist oil snobs who believe it's beneath their contempt to so much as cast a glance at conventional mineral oils on the aisles, and terminal, cheap "dumbdumbs" too stupid to find their butts in the dark with both hands. Has it ever occurred to you braniacs that the U.S. refinery infrastructure is physically incapable of supplying enough synthetic base lube oil stock (and I'm including both Group III and Group IV production) in the volume necessary to meet an entire year's new car consumer demand in the U.S.? (And, again parenthetically, I'm not even talking about the economics involved in the cumulative increase yearly of future new car purchasers or past model year "I've-seen-the-light!" converts, either.) On the "eve" of implementation of the new API/ILSAC "SM"/"GF-4" standard, there's ongoing debate within the industry about whether sufficient Group-II base lube stock supply will be available, long term, to meet it. But, enjoy your delusions gentlemen - it's less than three more months before the Easter Bunny arrives.
