.............SLOW DOWN! Left this Friday past to visit my 81 year old mother for the weekend. Set the cruise control at 65 mph for the entire trip. First stop, 218 miles & 9.4 gals = 23.19 mpg (flat ground and decreasing elavation first half of trip). Second stop and reached destination, 237 miles & 10.8 gals = 21.94 mpg (Texas hill country). Return home today, Sunday and third stop, 209 miles & 9.8 gals = 21.33 mpg (still in hill country and increasing elavation). Fourth stop and reached destination, 219 miles & 9.5 gals = 23.05 mpg (back to flat ground and increasing elavation). 883 miles and 39.5 gals round trip, cruise set at 65 = 22.35 mpg average. These numbers have made a believer out of me.......it's worth slowing down.

Yes, I was the slowest one on the highway. In each leg of my trip I increased my speed to the posted speed limit for 5 miles and set the cruise control, just to see if others were obeying the speed limit. Yep, I was still the slowest one on the highway, being passed left and right with the cruise set at the posted speed limit. Increased travel time is just not that much more but I do believe the fuel savings is worth it. Anyhow, just thought I would post my observations/results.
