I'm nearing completion of my AAZ rebuild and am monitoring my oil pressure. Seems like I'm getting around 50psi at startup, dropping gradually to around 40psi after a couple minutes. What's normal operating pressure for these engines? I've read anywhere from 15-80 psi depending on temperature and oil type. I'm using 15W40 Lubromoly at the moment.
Thanks.
cold startup I see it anywhere from 80-100psi, once oil is warmed up to operating temp it should sit around 22-30psi at idle. Cruising around you're looking around 40-60psi.
i am getting 8-10 psi (0.5-0.7 bar) at idle when fully warmed up. but i do not have oil cooler and now im using quite cheap 15w40 mineral oil. i think that synthetic or semi-sinthetic oil should give me more pressure. i have that readings at oil filter flange. i get 60-70 psi at cold startup.
engine AAZ
I have the same as zagarus and I am running 5w-40 rotella T6
how are you measuring it? known good mechanical gauge or a vdo guage
I picked up an autometer electric pressure gauge on ebay last year and it seems to be working fine. I trust it more than the army of blinking lights in my cluster
and i have tractor mechanical gauge
bought for just 6$
