I had a killer mileage day on the Navajo and Hopi Reservations during my cross-country drive. I drove from Gallup to Tuba City, 164.9 miles, and my mileage just kept getting better and better. It's a route with almost no traffic, so I could pulse up to 60 mph and glide down to 40 mph. That maximized my glide distances, and there were enough mesas with glide distances of ~5 miles to drag out my mileage.

At 81.8 miles on the trip, I was getting 54.7 mpg per my Scangauge. My calibration factor was 13.4%, even though 11.1% is more accurate, as I don't like to be surprised by disappointment when I fill up.

At 90 miles, i was up to 55.0 mpg. At 100.2 miles, my mileage was up to 56.9 mpg, and was still there at 115 miles. At 142 miles, I was still at 54.9 mpg, and the Scangauge trip mileage was right at 55 mpg driving into Tuba City. When I filled up, I got 59 (58.977) mpg actual mileage over the 164.9 miles, thanks to my Scangauge calibration conservatism.

I tanked up in Tuba City to preserve the excellent mileage before getting on busier roads to drive to St. George, UT. Over the next 210 miles, I was able to coax an indicated 49.7 mpg per the Scangauge. With the calibration conservatism, that's safely over 50 mpg for the last half of the day, and about 54 mpg for the whole day.

 

those numbers are umm wow crazy!

 

you could push mine over a cliff and it would not get that kind of mileage


good going

 

Crazy as it sounds, my mileage driving back to the Bay Area from Gallup NM has totaled 51.5 mpg over 1213 miles!

 

automatic?

 

Manual. I wish I had the final drive gearing ratio of the automatic. Manuals have advantages every which way over automatics, except for final drive gearing. There's a 36%! gearing ratio difference in the xBs. My Sentra has only a 4% disadvantage to its automatic version.

 

I know. That is my one engineering complaint on the xB.
my xB 5th gear is shorter than 4th in my accord.
