Well, it was pretty hot both ways, but hotter, I guess, coming back ("98 in the shade", literally). And, although we did use the A/C in both directions, we probably had it running a bit more coming back. So those things might have made a difference. I really can't think of anything else; I don't think there was a great deal of wind either day. There was more truck traffic going down, but I only tried drafting for about 10 minutes one time, just to see if I could detect any difference (until the saner? members of the family prevailed upon me - upon threat of banishment from the driver's seat - to cease such "reckless and dangerous behavior").


I am down to about "50 miles to empty" this morning (by the gauge; at "0 MTE" I have never put in more than 13.5 gallons, so I probably have closer to 80 or more when the gauge reads 50 MTE). I am going to fill up this afternoon or tomorrow morning, see what the calculated mileage is, and start over on a new tank to make sure I am "back to normal" and something weird hasn't happened to my car.
