This week I drove my average down quite a bit
I had a ~500km 2-up trip across Hungary (I had a lot of these last year because of family and official matters), and we got everything April could dump on us, strong head/crosswind, rain, hailstorm, cold spots where my hands almost froze in my already soaking wet gloves... it couldn't spoil the first tank too much (it became 3.02l/100km = 77.9mpgUS), but for the second one that fell entirely into this trip I got a shameful 3.53l/100km = 66.6mpgUS, the worst this year so far
Sorry, guys - I've done what had to be done.
The trip extended to a 3rd tank too which is yet unknown, but at least that leg contained hilly backroads where I do much better (P&G, DWL, some FAS) than on main roads where you just have to do the speed limit if you don't want to be
much slower than the rest...
