Keith,

I agree with all the comments about how our oil pressure gauges work. As
another point of interest: I've learned that some "modern" vehicles (I
don't have an example off hand) have "gauges" which are connected to
SWITCHES! In other words, the needles are really nothing but
non-illuminating idiot lights!

If a dealer sold me a vehicle with one of those, I'm sure I'd return it and
never buy another of that brand since I consider that such a deceptive
practice.
