240D mpg??

[george d]

I flew to Dallas last week to pick up my 1982 240D with manual transmission.

This is my first diesel vehicle, and I was expecting it to be slow, but it is better than I expected it to be, maybe because I had read so much about how slow they were.

I found an old original advertisement on the internet for the 1982 240D, and it claimed 27 mpg combined, and 33 mpg highway.

Well on my trip back from Dallas to Little Rock, at speeds of around 60-65 mph, on relatively flat interstate, my mileage was only 27 mpg.

On the next tank, which was a combination of city and highway, with some Ozark Mountain foothills in the mix, my mileage was only 24 mpg.

Are there any adjustments, or anything to improve the mileage? The motor sounds great, and runs smooth, and does not seem to smoke at all.

Thanks,
George
