An acquaintance of mine ( a liscensed diesel mechanic) worked in the Esso/Exon lubricant lab in Sarnia Ontario in the late '80s. early '90s. They used 6V92 Detroits as their test engines. Engines were hooked to dynos, run wide open and lugged down to about 1400 rpm and run for 100 hrs, tore down, wear measured and then rebuilt before the next test, I questioned him about how much wear would be evident in that short a test period but he assured me lots. He said at that time there was no multiweights equal to a straight weight. Undoubtedly, there have been improvements in multiweights, particularly synthetics in the 20 years since then.
