My gauge sits between the R and M in NORMAL in usual cruising at any speed.
If I'm reduced to driving in stop and go city type at 70+ deg F, or crusing the car lots the temp needle will swing up to between the A and L, the fan comes on and the needle returns to the R to M area within a minute. At least I know its working. I expressed my concern to the dealer a few months ago when it was in for an oil change. They tried to get it to overheat by letting it idle with the A/C on. It never seems to heat up with the A/C on because the fan is running!
Anyway, the service dept. said that it is not uncommon for a gauge to read a little higher as it gets older because of the resistance in the gauge. Seemed logical to me. I just turned 80k miles last week.
