On the higway
I had to make a trip to Syracuse yesterday, so I aired up my OEM Goodrich tires to 45 psi (well below the 50 psi max redommended), took off the roof racks and set out. I kept the speed at 60 mph and drafted a few semis on the way. I increased speed a few times to keep in the semi draft from about 3 Hummer lengths behind. The display under the speedo said 24.5 gallons used when I got there, which was within .3 and the mpg display read 14.1 which was an actual 13.76 based on the nav gps mileage shown. That was my best ever! I wonder if airing up the tires and keeping it around 60 really makes that much of a difference? I normally get in the 11s on the hwy. Anyone ever get over 14 mpg?
