My Workshop manual quotes :

-18 C to -1 C sae 10 or if not avalable sae 10/30

-1 C to +27 C sae 15/50

over +27 C sae 20/50

It quotes a myriad of brand names and types .... Shell Rimula X, Duckhams Hypergrade, BP Vanellus M, etc.

My engine has just been sorted by a local diesel engineer and he put in a Marine grade 10-40 ... he reckoned that any traditional non-synthetic 10-40 was fine for my raw-water cooled 4-107 ... Baltic summers of mid 20's C

suppose it depends where you do your boating. If always in the warm climes of the med or the carib, then a 40wt such as Rotella DD40 will be just fine.
