31.2 Mpg?
 

Dear all,
I recently got back from Dallas. During strict highway-only driving I was getting a constant 31.2 MPG. I calculated it by the old method of topping off the gas and dividing the miles by the gallons used AS WELL AS taking the computer's word for it which showed me. Do you all get this type of mileage also? Is mine too low or higher than what most of you guys get on long trips?

31.2 is good so you can be happy. I get 26-27 in mine on the highway, and used to get 29 with my W124 E320. Obviously results will vary with average speed, driving habits, wind, tire pressure, usw.

Just out of curiosity, how fast were you going on average?

Wow, the most I got was 27 mpg with my 300CE.

between 70-75MPH !

Not to bust your bubble, but one tankful of gas pretty much tells you nothing. Do an average after five or better yet ten tanks and that will be your real average mpg.

That fuel mileage is really too good to be true. I had the same car, but with the turbodiesel engine. It only got 32-33 Hwy MPG, barely beating your number. I currently have a 2001 wagon - same basic car, exact same drivetrain. It generally does 27MPG, plus or minus 1. I've seen 30 briefly - with a strong Texas tailwind during a road trip. Sedans generally get 1-2MPG better than wagons on the road due to cleaner aerodynamics.

Sounds about right
 

Designo_E320,

Your mileage results match mine - 2002 E320, 31 mpg +/- at 70 - 75 mph.

I agree. This Forum was created for Mercedes specific purposes.
I personally will not even bother answering a post with such a Sig...

Man mine sucks compared to ya'll i only get 13-14 mpg am i missing something here

EPA estimates for the 2000 E320 are 21/30 so getting just over 30 on all highway driving is not out of the question but is probably at the top end of what you'd expect. Lots of factors can influence mileage though. Wind speed and direction can have a huge influence. If you're driving into a 20 MPH wind at 75 MPH it's like driving 95 while if it is a tailwind it's like driving 55. Also, if it is hot and the A/C is running more your mileage will be lower than if it is cooler. Finally, like Len said, one tank is really meaningless. You can easily have ±1 gallon difference between fillups just on where the pump stops, even if you "top off" and that would have more than a 5% difference.

Delete.

Sounds right to me
 

Yes, depends upon driving style, traffic, wind, tire pressures. Straight CA freeway with no traffice jams, 70 mph on cruise, over 100 miles distance, I expect and get over 30.0 mpg.

Hello MR.
IN CASE YOU HAVEN'T FIGURED IT OUT YET that is my SIGNATURE! What a lame thing to bring up. Please follow your own advice.

Better yet Rockman59, please don't post in my future threads as you obviously do NOT have anything constructive to say. I am not here to argue about politics or any other subject. I am here to give and get advice only.
