There's a great article on the site for changing your oil for newbies (like me). The author uses 10-w30. But I see diesel motor oil on the shelf too.
What kind oil are you all putting in the M-35BC?

Thanks guys, one last question. The westerbeke Universal manual recommends not mixing Brands because of the combination of the different additives that each brand may use. I will pump out as much as I can, but from reading it seems that most people only get about three and a half quarts out of the engine leaving a 1/2 to a full quart behind. You think I should be concerned with adding Rotella to the remnants of last year's Valvoline? My thought is since I change it annually and I don't achieve a hundred hours anyway, the chemical combination damage would be minimal. Curious The Forum thoughts...

One point that has not been mentioned is to use engine oil that is for diesel engine.
