Making switch to 2014.5 - some ??

Don't know "how" but mine got 16-17 when I ran at 75-80 Mph; when I stay closer to 65-70 it is 18-19. I actually managed 19.5 on a 120 mile trip (betting had a good tail wind)

Just did 3800 mile trip Il to Ca to AZ yo tx to Il and ran solid 18.6 mpg.

I add Lucas diesel additive but nothing special.

How do you get better mileage? I drive about 65-70mph
Fuel economy is actually quite variable, and depends on a lot of different factors. Altitude. Temperature. Windspeed and direction. Driving speed. Regular diesel vs B5 diesel. How long you sit still with the engine running at idle. How hard you accelerate.

The sweet spot for fuel economy seems to be about 45mph. Faster or slower I'll get less. I drove across the Lake Pontchartrain Causeway, 24 miles, at 45mph due to fog restrictions, and topped out at 22.1mpg just as I exited the bridge, my best fuel economy ever in my Interstate. The listing dropped again as soon as I hit my first red light after the bridge, though.

On one trip, coming back to New Orleans from Lake Dardanelle in Arkansas, my average for the trip was a mere 14.7mpg. I was understandably concerned about that, but on the very next trip, I averaged 18.2 mpg. It dawned on me later that coming back from Lake Dardanelle, I was pushing the limit the whole 500 miles because I was in a hurry to get home in time to report for work, and driving much more aggressively than normal.

If I toggle the screen displays to the "Since Reset" readings, my average over 10,000 miles since I did my last reset was 17.7mpg. Which is a respectable number for a 5½-tonGVWR van conversion.

What I took away from my experiences is, if you drive like a feeble old granny who's afraid of traffic, you'll get great fuel economy. If you drive like NASCAR, you'll get crappy fuel economy. If you drive anywhere in between, you'll do well enough, but not anything to brag about. It still beats the 10~12mpg that you'd get from a gasoline-powered van conversion!

On the plus side, I've noticed on mine that the readout is usually a little pessimistic when compared to calculated mpg.

FWIW, my dealer advised me to steer clear of B5 even tho the MB 3.0L is rated for it.
