Bizzare one here. Oil gauge reads fine - ~30-50 psi while driving. While cool, just started, also fine. After 10 minutes driving, then at idle or while idling going down a hill, the oil gauge starts erratically spiking upwards toward off the chart. It ends up pegged at what would be over 120+ (the gauge is only marked to 80). It gets so it goes from 40 to 120+ in under a second when you stop when the engine is warm. It immediate re-regulates when acceleration is applied. Placing the car in neutral and revving to about 1800 RPMs also puts the pressure back down. Oil level is fine, was just changed, all other gauges work fine, coolant looks a bit low but not muddy (oily), and it seems impossible that there could be an 80+ PSI spike in under 5 seconds multiple times per day without destroying the engine, so what's going on?
Car idles right at 1k and runs smooth as silk. Oddly the AC runs a lot better on the highway than it does at low speeds, though.
