The normal metric hot one is 87 degrees C.
If in amercian, see if you can get 195 degrees F.
That's what I run in the winter.
An American thermostat may not last that well, and run cool again before
years and years go by.  
The standard traditional normal  F rating has always been 180, btw. Since
forever.

That's good to know, especially for this winter (the desert (great basin) is
dang cold!) I'll put a different thermostat in. I just finished a 1500 mile
trip for business and fun, got 19 mpg.  Better would be better.  And now
that the ambient temperature is getting down toward 10F, more in the heater
would be better, too!

What do I look for?  90 degrees?  I don't even know what denomination they
come in.

A cooler thermostat will lead, in general, to lower MPG, because of the way
the way the ECU interprets the signal from the Temp2 sensor...  ...The
cooling system in a waterboxer Vanagon could handle general duty cooling for
a small V-8!
