Usually when I ask to see your data, it's usually duh, I measured a few (partial) tanks, and .....I laugh at diesel owners who bought their $7K diesel option for the "gas mileage towing" yah they pull well, but big torque requires big fuel consumption, simple physics. Smaller motors need to work harder to tow and usually suffer more dramatic mpg/life span losses than a larger motor loafing along.
Buy yourself a little note book to record all your gas consumption (and maintenance) to see your long term averages.
Fits in your console/glove box/door pockets nicely for convenient data logging.
I have recorded every drop of fuel gone thru my van over 123K miles, my car over 68K miles with trip notes - one of these snowy days I'm going to build a spreadsheet for them, graph it and visually see how mountain driving/towing is so much different than flat land cruising, etc
Data tells the truth and it can be surprising
That sounds awfully cumbersome.
I didn't buy the TDI for towing. It's a daily driver, but it does do well on towing where I live. I only tow a bike when absolutely necessary. All I know is that get 525-550 miles on a fillup of 13-14 gallons every time. That's good enough data for me to know I'm running a fuel economical operation that I enjoy driving.
