Once the oil is hoot, the engine will not reliably hold 29 psi at 200
rpm. These engine typically hold 10-12 PSI for each 1000 RPM using 20-50
oil once the oil is over 220. The 1.8 switch will work if the oil temps
stay low and the engine is new, but it will give nuisance alarms during
certain conditions.

Hi,
The minimum oil pressure at 2000 rmp (By Bentley spec, is Bentley
right!!!)
is 2 BAR (29PSI). Why do we have a.9 BAR (13PSI) as minimum pressure
alarm
/ switch??? It does not make sense, the minimum should be at least 1.5 -
1.8 BAR (What is minimum?)

Get a damn oil pressure gauge!!!

Yea, Bentley is a big book full of it!!!!! In a 10-page section on the
lubrification subject, no mention of the oil pressure at freeway
speed????????????????????
