Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Twice this week, DW and I had to do a 5 hour round trip road trip, for reasons that are outside the purview of this conversation. Our new car has one of those fancy computer displays that keeps track of your mileage for you. On the first trip we got 27.1 mpg. But on the second trip (today) we only got 25.6 mpg. Both times I drove (I love to drive). I drove the same car, the same route, the same 64 mph cruise control setting (for the most part), with gas from the same gas station, etc. The only difference that I can come up with is that the temperature was in the low 50s the first day, and in the low 20s today. Does the outside temperature effect the mileage that much? No big deal, really, but I'm always curious about numbers.
