    In all three coaches, I used 15-40 Delvac. Same as the Detroit used. My Volvo used 10-30. Readily available and met the spec for the Yanmar in the Kohlers.

    Any name brand 15w40 that is rated for compression diesel engines.

    I’m currently running Shell Rotella T4 15w40 in our PowerTech 17.5 w/Kubota engine.
