c280 operating temp
I drive up a big canyon to work everyday. Today it was 100 degrees out, and I had the ac on the '3' setting. The altitude change is from 4500 to 8000 ft. The temp gauge crept up high, about half way between 100-and the max. Fan was on, thermo was changed couple months ago, and once I was over the hill it dropped back down around 97-100. Does this seem normal? I never saw it creep up that high and it freaked me out. The temp did go back down after I topped the hill. This is the first summer going up the hill, didn't do it last week when it was cooler.
I need to change the oil to 20-50, it's only got 10-40 in it now. Could that affect the temp when it's that hot out?
Seemed like it should have been a tad cooler, but under the circumstances do you think this is normal? Thanks.

What oil are you using ? I'd switch to mobil 1 if you aren't already using it.
0w-40 or 15w50.

If Garff did the work on your car make sure that the Antifreeze level is not too high......their antifreeze/water ratio is very high........I just had them do a service and my car heated up quickly and went to about a 100 before settling there. Brought the ratio to about 45-50 % and added a little water wetter and all is well.
I am also guessing you went up Parleys....well, that is a very hot canyon anyways.....

I'm not too worried. But I'm curious if you guys think 110 is too high for those conditions? It would drop back down to 90-100 once I was over the hill and entering PC. Thanks for your thoughts.
