I did the other day going to the VAMC in Mpls, MN. It is about 196 mile round trip and going up I shut MDS off using the +/- 5th gear setting. According to the EVIC I averaged 16.3 mpg and it was 8 degrees out and I ran 70 all the way. On the return trip I reset the gas mileage and drove with MDS on and received a 14.8 mpg, the temperature was 12 degrees when I drove home. All I can say is the truck feels more responsive and doesn't get any drone in the exhaust with MDS shut off. By the way this is the best mileage I have gotten all winter by shutting off the MDS as I alway ran it before. I also notice a 250 rpm difference between MDS and no MDS at 70 mph. If I were to run at 55 mph then the mpg's go way up but that is not my driving style.
