Have you tried the 20W-50 in your onan yet? I tried a multi-weight oil in my Emerald 3 6.5 once and found that it burned through way too much oil. I do not recall which multi-weight oil I tried, however, and I did try it during the summer.

It's important to keep in mind that she'll run the overhead A/C for hours with the mercury up and over a hundred and only stop when I hit the kill switch.
