I see you had a few "real world" 100-mpg tanks lately, congratulations!
At least I had my 90-mpg one too, the best since I have these tires on. I needed to get down from the High Tatras (filled up in Zakopane, Poland) and cross the Low Tatras completely, along with the whole Slovakia, then come home through a part of Hungary. 3 countries for one tank, I liked it
