Not sure.. I have a 207 e320 and also livery in FL. What model do you have? I always thought 2k rpms was high for 80mph.

In any event, whether using the car's computer or the actual miles/gallons pumped method, my 06 E320CDI gets incredible mileage for a 4,000 pound car. I drive it mostly between Tucson and Phoenix which is about 100+ miles on pretty flat desert. At 80 mph the computer says I'm getting about 40 mpg. Tried it a little slower at 77 mph the last time and computer said 43 mpg. Car has 90,000 miles on it.

Nice! I've seen 43 MPG many many times while cruising on the highway at 75 MPH. I've been averaging 35-36 MPG mixed driving and I can't complain.

Perhaps its my 19" wheels and low profile tires, I average 28mpg on mine, seems low compared to others. Anyone getting higher mpg on 19's?

Have you verified the accuracy using a GPS to make sure the odometer reads correctly? If you have tires that are larger diameter than stock you'll be off and your INDICATED mileage will be lower.

No I have not since it did not bother me. 16" stock tires ran 807 rev/mile while 19's I'm using are 818 rev/mile, a mere 1.5% difference.
