Snake oil. The stuff specs out like a mix of gear oil and chain oil (thick and tacky). It causes regular oil to foam up. Foam doesn't lubricate very well. There is a fortune made on additives, but every car and truck manufacturer tells us not to use them.

Agreed. See here for foaming in action.
I dont want my engine sucking foam at 5000 rpm!
Something else to think about is that when the oil foams up, it increases the oil level in the pan, possibly causing the crank to whip the oil, causing even more air in the bearings and making the foam problem worse. This is my theory, of course, but I think it makes sense.

I was talking more along the lines of after the pump sucks the oil up. I was under the impression that the pickup was designed to prevent aeration and to help alleviate it when it happens. Then when the oil goes through the pump I thought as long as you dont have too much air it would compress the air and get rid of the aeration. As long as the pump doesn't cavitate and create more air in the oil.

The pickup screen may break up some of the bubbles, but the air they contain will still be sucked in. Once it's that far, it's on a one way trip through the filter and into the engine.

Huh, that test looks good and everything, but, i have recently tried the lucas oil in my I6, it is the only thing that has quieted down a knock, slowed if not stopped a leak, and it has raised the oil pressure a little. Now, I agree that not using any additives is best, but, as far as I can tell, this stuff has done what it said it will. Just my $.02
