I am about to launch my sailing yacht. I have a 100 H.P. Yanmar turbo diesel engine with aftercooler in it. Yanmar recommend a 15W40 oil for the engine.
Does anyone have a specific oil to suggest to me? I am thinking of using a Shell Helix Diesel HX5 15W40 because it's easily available here in South Africa.
They also recommend that I use the same engine oil in the gearbox (KM4A. Shouldn't a gearbox take a special gear oil?
