Want another gauge?
Oil temperature gauges on liquid cooled engines are not that useful,
except for R&D. If you want to put one more gauge on think about a
coolant pressure gauge. A little thing no one ever thinks of-but it
lets you know if you have a problem very effectively. As long as you
know the pressure your cap vents at you know if you are going to start
boiling over or not.

And you can cross off an O2 gauge unless your still using a carb.
Unless you want to see lights scrolling back and forth as the computer
constantly hunts for the perfect mix. :)
The Vac/Pressure (or just Vac) is a good thing. It will tell you if
you have a plugged cat, bad valve, intake leak, and is a good overall
indication of engine health and happyness.
Yea.. I have one. It's neet but I'd trade it for a fuel pressure gauge.
A pyrometer might be more useful as an indication of overall rich/lean
Tranny Temp for those that tow stuff.

Re: Want another gauge?
A pyro, or correctly EGT, is very useful for tuning but if you are not
rejetting or remapping your fuel delivery it's useless on a gasoline
engine (or unless you have a mixture **** on the wheel like they did
iin the 1920's-aircraft still do.) Diesel operators like them for
driving technique.
The "vacuum" gauge, more accurately manifold pressure, is indeed
useful. Especially on auto trans vehicles. It should be calibrated in
absolute pressure, inches of mercury, which is not the customary
automotive way. If you have a carb with a venturi vacuum port (for
distributor advance) it's fun to get a double MP indicator, hook one to
the manifold, one to the carb port-but not that useful. The days of
cheap surplus aircraft instruments are over-they had radium dials and
were bought back and buried.

Re: Want another gauge?
Coolant pressure tells you nothing that coolant temperature doesn't. When
your system is under pressure, there is a one-to-one relationship. After
going through a couple of boil-overs with both gauges in place, you would
realize this.
There is a vacuum indicator on my YJ. You are supposed to watch your shift
points, so that it does not come on. Once you get the hang of driving the
vehicle, it is useless.
One thing that I would like to see, is a gauge that tells you the "edginess"
of the person in the passenger's seat, and when she is about to boil over.
Then, you could back off on whatever you are doing. ;o)
