What engine oil for a MAN?

Gonna have to buy some engine oil with my keyfuels card. What kind do I need for a MAN xxxl on a 10 plate? Cheers.

15w40 low saps, synthetic

10w 40 low SAPS Fully Synthetic

Thanks :slight_smile:

Don’ know about MAN but in general should not put fully synthetic in unless that is what it has in.

do not use mineral or semi synthetic in the MAN, it will do more harm than good :wink:

Why? Oil is oil, it all comes from squished up dinosaurs, there is no difference between mineral or synthetic oil, a 15W40 is a 15W40 (or whatever grade you choose)

MAN may specify a specific grade, although I very much doubt that internal tolerances are so tight as to require an oil with an extremely light film strength.

EGR engines, as used in MANs do create a lot of soot, but even then a synthetic oil is no better at keeping that in suspension than a mineral oil of the same grade.

It could of course just be one of those weird things, I know people who switched from one brand to another and saw oil consumption and even MPG suffer/improve, delete as applicable.
