I know this question has come up in years past but I'll ask it again.

My diesel (Volvo MD2B) now has about 200 hrs and I changed the oil at 50
hrs. I changed it again yesterday, just because it had been over a year
since the last oil change.

Beyond the 50 hr break-in oil change recommendation, I find no further
guidance in the owners manual.

What is the normal change frequency for a sail boat aux. engine when it is
in frequent use. (cruising with daily operation)??

FWIW. I'm using Shell Rotella-T 15w40 and change the filter each time.

Thanks,

HI Steve, with most diesel engines that have presure oiling and oil
filters, the standard is 200 hours max for lubeoil and filter. Then
if you don't put 200 hurs on the engine in any one year, do an oil
change at the end of each season. This leaves fresh oil in the engine
during winter layup and no acid buildup from high sulfur fuel while
the engine just sits. With a non-pressure Lube system, and no oil
filter, then it is every 50 hours of operation, and a fresh oil change
at the end of the season in preperation for winter layup.
