Question-how do you appraise the superiority of one engine assembly lube over another. I simply went down to NAPA, purchased a tube of the white slime they sell, used it liberally with a quart of 10W30 motor oil, and ran the Chevy 400 I built 230,000 miles, selling it after the car it was in pretty much desolved in Minnesota salt.
Oil consumption was minimal. The exhaust valves were all white/gray.

Im serious.

Best,
Ted
