RE: Mann oil filter for M20 engine

[Horst Apfelthaler <Horst.Apfelthaler@xxxxxxxxxxx>]

Hello everybody,

I can tell you my personal exerience with Mann oil filters on M20 engines. I
noticed 10 degrees more
oil temperature and 1 bar less oil pressure during hot idling. -  Even the
oil pressure lamp was flickering.

After swapping the Mann filter for a Purolator or a Bosch filter everything
was OK again.

These symptoms happend with 2 Mann filters (1 bought 5 years ago, last
bought 2 years ago - both
thrown away after 1000km).


Regards
