I will admit. I think spending time in Colorado may have gotten the computer a little "high" on this particular estimate. The REAL MPG on that tank, though, was 17.7. I never thought I'd see nearly 18 mpg on that truck. hahahaha
16.1 was the best I ever got out of my truck. I only ever hit that mark once and haven't seen it since.
Yeah, I can sure understand that. I think the only reason I got this high was mountain (highway) driving.
This is what our 2016 suburban got on a trip to Indianapolis this past weekend. I ran E85 in it for the trip. Normally get 21mpg on 93 but this 18.8mpg isn't bad considering it was loaded with four adults and packed in the back with luggage, running chair and wheel chair. Also going through the mountains in West Virginia. I have to admit, the roads in Indiana stink. I bet everyone goes through shocks on a yearly basis.
