what's the right (engine) oil level for the track

[trygve]

I've always just made sure it was full or reasonably close to full. It never swamped the AOS.

(When I had the oil cloud problem with the car last year, the AOS was a prime suspect at first and I found that the oil level had an effect on the problem (less oil, fewer clouds), which supported the AOS theory. But it turned out be rings, not AOS, and the compression test proved it. And Brad visually confirmed the rings were the problem when he finally laid his eyes on them.)
