Yes, you read that right, mileage gauge says it has 308,000 and stuck the oil pressure gauge at full. While I was driving through Iowa yesterday from Michigan, I noticed my oil pressure gauge was reading at the top of the scale (80 PSI, in some cases bouncing past that) No problems at all, temp gauge was just below the middle of the gauge (210 F), A/C blew nice and cold the whole way, probably averaged 16 MPG during the trip, and most of the way I was running about 70-75 MPH with an engine speed of 2,200 or so, but the oil gauge managed to get pegged. The one other problem I had was a CEL that was due to a P0420 (Bank 1 catalytic converter efficiency below threshold. One of the most common ones I've seen, so I was content to erase it and continue on. It did not come back.) I babied it for a bit until I could stop and check it out. When I did, there was no major, active oil leaks, opened the oil filler cap and say a bit of smoke and fumes coming out of the valve cover, but nothing major. No joke, a smouldering cigarette would probably put out more smoke. When I restarted the engine, the gauge dropped to just a bit above zero, and went to 35 or 40 PSI at idle, the highest it got the rest of the trip was about 60 PSI. I should also mention I did have this problem before on a long road trip doing the exact same thing. I just let off the speed for a bit and it went away.
My question is 1. Has anybody else ever seen? and 2. Is it normal for the gauge to do this during extended high-speed driving? Should I be worried about this or just be happy that I seem to have a healthy engine that's putting out good oil pressure? If I should be worried about this, where should I start looking first? Oil pump? Sending unit? Gauge? Oil/filter selection? (Before anyone asks, I run the Mobil 1 stuff that's designed for high mileage engines, 10W30 at the moment, and a K&N filter.)
