Actually the exact opposite is true. Cars get better mileage in warmer temperatures. I always notice a significant drop in mileage in the winter months.

I think that extra 5 mph could be part of the problem. It seems like mileage really starts to drop off fast once you get over 2,000 rpm's, and that is right about where 65 mph is. Push it up to 2,500 rpm's, and that could have been the difference between you getting just under 20 mpg, and me getting 23 mpg.

Also, I don't know what gear ratios were available, or if there is some other difference between a 2001 and 2002.

Between the three Explorers we've had at work as company cars, I have driven four generations of them: 1997, 2002, 2005, and 2009. They have definitely gotten better with each design.

The 1997 was a puddle jumper, very under-powered with the 4.0 L V-6 pushrod engine, and poor mileage; I would rave about my 2002 with the 4.0 L SOHC; the 2005 was smooth riding and dependable, getting 24 mpg on the highway with a 4.0 L SOHC; the 2009 is a fabulous vehicle -- quiet, comfortable, good mileage, really nice, and also with the 4.0 L. Maybe you ought to consider another Ford Explorer.
