Liang,
Actually, a low or lowering oil pressure over a long period of time
indicates excessive wear on your engine's internals. A sudden loss may
indicate blockages, broken pump, a hole in the block, or a lack of oil. You
can't really get a gauge that will tell you how the oil it's self is doing.
It can't really let you know when to change it or how dirty it is unless
there is an extreme case like listed above.
