Yeah I know, except that oil temperature is unlike coolant temperature.
Coolant temps are regulated to a fairly tight tolerance in modern engines
for fuel econonomy and emissions reasons, but "normal" oil temps can vary
over a wider range. If you apply that range to the S4's oil temp gauge,
you'd find that it is pretty close to being "in the middle".
Also, the original poster made the remark that the oil temp gauge is
"relatively inaccurate". I wonder why he believes so. In my experience
with these gauges I find them to be quite accurate. Of course the oil
temp also varies over a wide range depending on *where* in the engine
you measure it, but that's the nature of it and you can't blame the gauge.
