Engine was <121degF until i hit a 55mph zone 6 miles from my house.
150degF after driving for 8 miles at 55mph, atop a big hill
168degF at 10 miles in 45mph zone
188degF at 14 miles after some more 55mph
198degF at 16 miles after a large uphill at 55mph
196degF at 18 miles previous to the 25mph zone
189degF at 21 miles after driving 25mph for a little while and parking in the lot. (With very little load, the car actually started to cool back down!)
Trip home is as follows: 41degF outside temp
After around 2 miles of driving at 55mph, the temp was up to 195-ish degF.
And that's at 25degF...
Imagine how much fuel we're wasting at 0degF or lower!
THIS is why I want to install AGS!
Neat. Learn something new everyday. But what are the ill effects of operating at 10-20 degrees below max? Anticipating you will say reduced fuel economy, how much?
