Good point !
We did a complete overhaul on the engine of our Opel Rallye car only do
discover that the oil pressure gauge was broken ...
OK, the engine was a bit worn and in need of a new hotter camshaft and a
tougher clutch but none of that was the cause of low oil pressure !
The original oil pressure sender is almost always of good quality and
accurate so if you�re installing an oilpressuregauge use a T-joint down at
the engine and have the old sender with warninglight in use too !
After a while you�ll get fed up with staring at a gauge and the light will
always alert you !

BTW
As a little curiousity - the Oil light sender works as grounding, low
oilpressure means the lightbulb is grounded and lights up so on the above
mentioned Rallyecar we ran a wire from the  coil to the oilsender with the
result that if we lost oilpressure the engine would stop !
