Thanks for the video link, it expands on my thinking. It's interesting that the shop that overhauled the 6v92t in my 77 coach recommended using straight 30wt oil year around. They did a lot of work on oilfield 2-stroke engines and claimed to have never seen a problem with the lower viscosity oil. The pressure was a tad lower but that was all. This is getting exciting.
