250,000kms. 

I can't tell you what is 'normal,' but based upon my experience with my '88
V6, I would say your situation merits investigation. Mine runs at about 75%
needle deflection at speed and never drops below 50% at idle - but the
indicators probably vary from one vehicle to the next.

Just my opinion; but, if my readings were that low, I would definitely hook
up a gauge and see what the actual pressure is - otherwise, it would
probably drive me nuts. Just pull the oil pressure switch out (just in
front of the oil filter) and connect an oil pressure gauge in the port. It
should be at least 4psi at idle and between 36-71 psi at 3000 rpm.

If the oil pressure is confirmed low, it could be caused by several things
including oil leakage, poor quality oil, a faulty relief valve in the oil
pump, a bad crankshaft bearing, or a clogged oil filter.

Before I did anything, I would change the oil and filter if not already
done. A higher viscosity oil will usually result in a bit more pressure.
