You are driving me insane reading this!

Why oh why don't you just get a mechanical oil pressure gauge and put it
in there instead of letting those so called 'mechanics' rip you off
blind?

None of the -------- 'fixes' you have posted here has been valid.

Arrgggg!

Or are you one of those 'fools and their money'?

On that note, I am off bush running in my Jeep for the weekend, good
luck.

what if I used Hyperlube, instead of Lucas?

Man, I don't know what the deal is, all I know is that I let the oil
go to long in the dead of the summer, when I was doing a ton of stop
and go driving, stops, and re-starts. About 4 or 5 a day.

The problem first presented itself after driving 40 minutes or so at
70-80 MPH, then sitting in traffic for another half hour or more.
That's why I think it has to do with the oil. But I'm probably wrong.

Correct, so therefore there is 'Nothing' wrong with your engine!

'If' the new sender works, then you have a defect in the wire to the
dash or a defect in the dash circuit board. A cold solder joint in a
circuit board acts just like you describe. The ground for the sender is
bolted to the dipstick, look for some small black wires there, maybe one
is bad.

For less than 50 bucks you can install a mechanical oil pressure gauge
under your dash and forget about the stock one.

For that matter, you don't 'need' a gauge at all. The engine will rattle
really good if it actually does lose oil pressure.

Today it took 15 minutes to bottom out. I'm thinking if I put a higher
weight oil in there it might do the trick. I'm also switching out the
FRAM filter. I read of another guy who changed out the Fram and the
problem went away. I noticed that the Fram Tough Guard has smaller
holes than the Pure One.
