16.3, not too shabby considering that it’s been a few weeks since I’ve driven on the highway. What I don’t understand is that it rose up from 14.7 a few weeks ago, with no change in driving style or location. In turn, the 14.7 rose up from 13.1 before!

Maybe it idled more in the past - that really kills MPG. At noon today, it dropped from 16.4 to 16.2 just from idling for 5 minutes.

At least it’s not 11.5...

A good friend of mine’s 300SD gets city mileage that is better than my highway mileage, 28-30 vs 27.
