Engine break-in vs. mpg
« on: September 02, 2013, 07:27:21 pm »
At the start of this summer's tour I had around 12,000 miles on the coach  During the trip last year the engine changed over those miles as indicated by the engine-specific calibration factor of the Scangauge.  However, fuel consumption remained at a flat, unchanging  average of 9.4 mpg.  No sign of "engine break-in" that people talk about.

This summer after 4 to 5,000 miles, the average mpg and ScanGauge calibration finally began to rise as we meandered to the West coast.  (In CA and OR the average went down. Is their gas different?).  Never-the-less, back in Florida at 25,000 miles the overall average for the tour was 9.6 mpg.  I now think "engine break-in" is real.

I feel that this years gas mileage is better with over ten k on the rig.
