Correct oil for Bukh engines

[alegood]

Had an interesting conversation with T W Marine this week.

 

Did an engine service on a DV20, and the owner had been using 20 w 50. I told them this was wrong and to use SAE 30 (which is what I had been using)

 

HOWEVER, on speaking to T W Marine whilst ordering bits, discovered that the correct oil is SAE 20. This makes starting the engine far easier in winter apparently. You can use SAE 30 in the summer, but SAE 20 API CC or API CD is recommended for all year round use.

 

This applies to the gearbox as well. SAE 20 API CC / CD all the way. (The workshop manual specifies SAE 10 for air temperatures below 5 degrees celsius, but I haven't been able to find any)

 

AND this applies to ALL Bukhs, Dv10, DV20, and DV30.

 

Hope this is of interest to people.
