Oops. I forgot about you asking about the temperatures.
In slow traffic and city driving with stop and go's, I typically hit 221F for engine temperature, and coolant gets as high as 197F. But on the freeway with light traffic going around 70ish mph I typically get 217F for engine oil, and 195F for coolant.
On cold nights, I've seen 215F/185F but very rare. And this is going 100+ mph (which I don't recommend doing
) for 15-20 second intervals.

LubroMoly / LiquiMoly is a good oil. Was running it in both my E36 M3 and Audi S4.

If you have a 180 degree thermostat then the unit will stay closed when cold and gradually open up as the temp reaches 180 after which time the stat is fully open, if outside temps drop the stat will slowly close to try to maintain 180 or in the case of extreme temp difference the stat will close completely to allow engine temp to rise. Engine temp should be stable to the temp of the stat. If as with Ezec63 the temp will drop 10 degrees then that just tells me the stat is very slow to react. Coolant Temp in both my cars remain constant even in hot weather when idling in traffic, but of course the fans do kick in to hold the temp down.
