Diesel Oil

[Bolitho]

Any advice on a good diesel oil for a Yanmar SB8 ??? If I have to buy one of the big automotive company diesel engine oils which should I go for ???I sail in the Great Lakes and winter on the hard in southern Ontario.

Shell Rotella at the weight the manufacturer recommends, most cases that's 15w-40, pick it up at Cosco, Walmart or AutoZone.

What does the manual say to use?

The manual typically will not tell you what brand which is that the OP is asking, well on second thought I'm sure Yanmar would want you to use Yanmar brand.

Shell Rotella and Chevron Delo and the most used in the US and probably the most easily found. Both are excellent oils.
Personally I think you need to pick a brand / type and stick with it, maybe old wives tale.

The brand of oil is all but irrelevant. The manual will/should tell you what oil weight is appropriate in a given temperature range along with the required API rating.

Use the oil that meets the standards set in the manual.
