LO Filter - Differential-Pressure Alarm
Lube-oil filter differential-pressure alarm and change-out threshold per OEM guidance - typically 0.8 bar alarm and 1.2 bar change-out for 2-stroke slow-speed engines.
Status
Normal
Formula, assumptions, and limits
Rapid rise (>0.1 bar/week) on clean cartridge indicates ingress of debris or degraded LO (acid + sludge). Always sample oil before changing filter - root cause often upstream.
