Congrats! It will be interesting to see if you can break that with the correct spark plug gaps.

I get better mileage in my commute than on road trips since I refuse to go 70 on a 70 mph freeway. I do 75. Still averaged 40.6 though at 75.

Same here. I can drive nicely enough in-town, with an average of speed typically 30-33 mph, to maintain a 40mpg+ calculated average at the pump. While highway driving should boost that significantly, I find that going 70-75mph to keep up with traffic actually skews my numbers a bit since my average speed goes up, but my fuel economy barely does.

I've also had to use A/C this entire last tank of gas, which I know will hurt my numbers quite a bit. I may have my first sub-40mpg tank in a long time when I fill up tonight.
