Oil pressure drop at idle when engines warm, '96 4.0L JGC
 

Vehicle: '96 JGC 4.0L (108K miles)

I replaced the filter and oil about 3 weeks ago wtih Synthetic Quaker
State 4X4 10W30 (first time for synthetic)

About a week ago, the oil prssure gauge dropped to 0 when at an idle
after the engine was warm. Now that I've been watching it, it
normally runs around 40 and drops to 20 when idling. It will still
drop to 0 after a while and then if I run the RPM's up a little, it
comes right back up.

I've been good about replacing the oil before but this was the first
time I put Synthetic in it. Could this just be the oil pressure
sensor?

You really didn't want to switch to synthetic in the middle of an engines
life. It could be the sensor but I would also change your oil back to dino
oil quickly, if it isn't already to late... Also, don't get fooled by some
'4x4' label, because... what the hell does engine oil have to do with 4
wheel drive??? (except marketing ploys..$$$)
