Shell engine oil API CD

Quite right. Having found the tech sheet this has a TBN of 10.5 which I think is too high..
In the meantime I've found Morris Lubricants GoldenFilm SAE-30 which has a TBN of 4 and is rated API CC would certainly do for my Bukh.....

Yes - I bought a stock of Morris 15-40 CF grade - good price too.
