What is your oil pressure at IDLE?
Anybody with an M103 engine wanna tell me what their oil pressure is that 80C and in Drive at Idle?
Thanks!

1 Bar at idle once fully warmed up. Being at 80C doesn't necessarily infer the motor is warmed up.

My cars are diesels, but I don't think that makes a difference. With the engine fully warmed up like being on the highway it should be between 1-1.5 bar. When the rpms get up to about 1500 your pressure should be pegged at 3 bar.

Yeah the M104s have a 10:1 compression ratio... maybe that has an effect on the pressure... (M103 has 9.1:1....)
