I've got a 454 with about 150 hrs on it. Running 15-40 wt Rotella only about40 psi 3000rpm cold oil, only about 20 psi hot, practically zero psi when hot idle. No noises from motor, runs ok, but have lost about 8 mph off the top end from last season (48 down to 40). Motor runs about 150 deg, never oveheats. I switched to KN high $$$ oil filter, no difference, and yes I tried a mech oil gauge to verify readings, and it was identical to elec gauge. Is my motor dying a slow death? I've never had a running engine with such low oil press readings. This is an 89 Chaparral 2550 SX
