Richard,If the Rotella oil has the same rating required by your manual, you should be covered. Just dont use oil that is for a gas engine. I did this in an old VWdiesel car. Within 1000 miles i was rebuilding the engine. I use Delo 400 in my yanmar, because I bought 10 gallons for half price. If you wanted you could change you filter monthly. Doing it once a year, your oil every other is in MHO ok. The biggest thing we can do for our diesel engines is run them at full cruise power for at least an hour on a regular basis. I say, because a friend would run his diesel just long enough to get in and out of the marina. Never letting the engine get fully warmed up. It finally died from a severe lack of compression.

Ok; respectfully.... you guys now have me totally confused...what one swears by, then other would "never" do....we mere mortals, (as in not mechanics, scientists, or otherwise experts in the field), need to know what we can reliably do for our good old Yanmars... so, can I use Rotella for diesel, (30 wt per C&C manual) or not...and even if not required, does it hurt to change the filter every year whether need or not...? Many thanks and please know that I, for one, love to see and partake in this kind of discussion, I just need to know what to do...

When I installed the new engine in my 40 two years ago I asked the mechanic about using synthetic oil and was told absolutely not! For the reasons already explained here.
