Getting better than 10 mpg will be tough. Best advise is slow down. You are pushing a box down the road. I can get 12 mpg on the freeway. But only takes a couple of start and stops when I get off the freeway to drop it below 11. Overall, with 70,000 miles we have averaged 10.3 mpg.

10 is pretty good to average. I have gotten as much as 12 on individule tanks. Not many though. I have the 6 speed upgrade so rpm is about 1950 at 65. OD lock out goes to 4th. It will use 5th it it needs it.

Really don't remember rpm at 60 but about the range you state.
Don't think a 6 speed upgrade has ever been done. In fact, don't know what that is.
Ever hear of anyone experiencing an Edge CS that really is of any value???
Thanks

The kodiak motor homes are to heavy for gearing higher than 4:48.
The sixth upgrade is good for maybe a half mile per gal.

Sorry to hear that. If I slow down any more, I get run over. I drive 55-60 and still 10mpg
Thanks

I try and drive 55-ish and compared to 65 MPH get you +- 35% better mileage. I just figure I am in zero rush and its way safer to drive a 55 anyway.

Be well,

Further about the sixth speed, its much quieter in the cab as well as longevity to the drive train. The shift points seem to be better suited to the weight we move around. I am now pulling grades in 5, 6 that were 4th. Just more comfortable in my opinion. I am chipped by the way.

Your tuner may not be helping you mpg. What tune are you running? My best MPG is at 1900 to 2100. That gets me speed of 55 to 65 mph. Before I purchased larger tires. 2100 rpm's and 62 mph gave me my best MPG. With larger tires I run 2000 rpm and 62 mph. Gives me about same MPG. I have tried to run 55 mph. I always get less MPG with that speed.

I set the cruise @ 65 and l let the trans do the thinkin. I didn't buy this thing for the milage but keep track of it as it can alert you to possible problems. I'm averageing 10 @ 65. Some tanks better some less. I have done a 4 inch turbo back exhaust so it breaths pretty well. Power is great and stays on speed up and down the hills.
