Yep, The 2002 FSM minimum pressure specs are 5 psi/idle, 35 psi/2,000. There were a couple of threads, one a few weeks back, another last year about this time, wondering about flickering oil pressure warning lights. The first time around I dug into my gauges and copper tube box and jury-rigged a SW 0-80 psi 270 degree mechanical gauge with a T for the sending unit. Ran the gauge to the air intake grille dent area in front of the driver's side and left it there for a week. Lowest I saw, hot idle, was 15 psi, and around 47 psi, hot, highway (60 mph/2000 rpm cruise.). Someday I fully intend to permanently install a mechanical oil gauge, maybe in the flip-up ashtray puka, because I hate and distrust idiot lights.
