oil pressures

[JP]

I always run 5w40 on our engines working on the base assumption that the operating oil temperature is 90-110celsius as w50 and especially w60 never gets to proper operating temperature and therefore you end up with noisy lifters due to bad circulation.

Oil pressure at idle is around 1-1.2bar. At 2000rpm factory stock test figure of 2bar and then an additional 1bar/1000rpm until approx 5bar.

Providing these sort of values are met I always feel that good circulation to aid bearing cooling is better than higher pressure with poor circulation and poor cooling on a turbo engine.

I wouldn't trust the stock oil pressure sender as far as i could throw it, if you have any unusual readings at all its the first thing i would swap out. I've seen a difference of 1bar at hot idle between two senders.

i use 5W/30 castrol.5 bar cold and 2bar when hot on idle and when revs incrise to 1800-2000rpm its 5 bar again.i would try to check sender and gauge before decide to fit new oil pump.

Agree! Also if you have any type of upgrades ln oil lines and turbo oil prsure might drop...
