Hi - looking at a 98 roadsport A, the oil pressure according to the std caterham gauge was sitting at 2 at idle, then increasing to 3.5 ish / 4 under load. Is this normal, as it seemed a bit low to me?
Sounds fine. Point about the sender being notoriously unreliable is true plus the make and grade of the engine oil can also have a marked effect too. On the face of it though, I would say the readings are no problem.
