My work van (1993 Chevy G20 305 auto) started showing different oil pressure readings about 6 months ago. It used to sit close to center with slight rises during acceleration and slightly lower in park and idling. Now at idle it reads maybe 15 and on WOT it will top out past the reading (70). A mechanical gauge mirrors these readings. No performance drop, no extra noises, no added oil usage. Gets 5W30, usually synth.
