Earlier this weekend I decided to check the mileage of my pickup, which I hadn't done in the nearly 2 years I've owned it. It averaged just over 22 mpg over 465 miles, which isn't bad considering that some was in town, and 1/3 of that was on the interstate doing 70-80 mph. Today I decided to start checking it again, at slower speeds. I left my house and kept it right at the speed limit. I wish that I'd counted how many cars passed me, sometimes it was like watching a parade. What was most embarrassing was when that Prius passed me. 
Apparently my truck didn't like going that slow, either; after about 70 miles the check engine light came on. Granted it's a Chevy, so that's to be expected; yet it's the first time I've seen it on this truck.
I did good most of the day, never exceeding the speed limit. It was about 200 miles round trip and I was only 20 miles from home when I came up behind a string of cars which was poking along at 40 most of the time, only speeding up when somebody could get by them. After about 6 miles of that we came to a long straight stretch with no traffic; and I burned up all of the gas which I may have saved in the first 180 miles, passing that line of cars.
