[Vwdiesel] 10 Barl Pressure Gage

[Publius]

I have a diesel caddy, and my oil pressure show 5bars on start up and then pegs out at 10bars within 1 minute.

what PSI gauge should I get for it, and do these readings seem normal.
I am running regular oil for a 1981 caddy

I bought a new Rabbit diesel back in 1979 & later installed a 100 psi oil pressure gage. Ran Amsoil 10W40 full synthetic. The 100 psi gage always pegged on start up. Replaced gage with a 200 psi gage & it also would peg when the engine would rev a bit while cold  but when once warmed up would operate under 100 psi as I recall. I also recall its idle pressure around 30 psi when warm. The 1981 Dasher diesel has a 100 psi gage which also pegs at 100 psi on start up, cold engine. On my 1982 Quantum TD, start up, cold engine is around 80 psi as I recall. When I get around to it, I think I will put the 200 psi gage in the Dasher & the Dasher's 100 psi gage in the Quantum. I wonder if the psi difference is due to oil pressure being supplied to the turbo in the Quantum which the Dasher doesn't have?
