ok. we had a rep from BG come to our shop and he brought along an LT1 mock-up(and engine on a stand that runs). when he brought it he changed the oil and put in quaker state 5w-30(our shops bulk), a fram filter, and a can of BG MOA oil additive. he started the engine and let it run for about 15 minutes. then he lowered the oil pan from the block! after he did that he took us back inside the shop with the engine still running and ordered a bunch of pizzas. after about 35-40 minutes we went back out to the oil starved engine. it was still humming along at 2000 rpm, just as smooth as when he first started it.

cliff's notes: BG is the sh!t. hands down.
