1992 Buick Roadmaster Sedan - 5.7L V8 Engine. 56,000 miles. Oil pressure gauge is reading way past the 60 mark. The needle is actually horizontal. The gauge will then return to an area between 30 and 60 while the vehicle is idling (i.e. at stop light/sign, etc). Is this a sign of a bad gauge/sensor? Vehicle appears to run just fine. Everything else is normal except the gauge reading.
