I only use my calculator app to do the MPG. I opened it up today after filling up my and my wife's TDI beetles, and the last tank MPG was 47.33
I put in the miles and gallons, and it was 47.33 again
Totally different drives on those tanks, and somehow I got back to the same results down to the decimals.
Weird.
Our MkIV get about 44 in the winter or town, and 46-ish summer, mostly a mix of urban/rural.
I've only broken 50 a few tanks in 150,000 miles between the two of them.
