hmmm 1000km on a tank... that would be 621.4miles
I almost get that on the urban cycle!.. well not quite, but I did average that from the car as stock and no hypermiling.
but them I get over 15 uk gallons in tank!
.. only downside is at the cashier.. almost topped £100 a tank at the peak of the oil spike.
better aim for the 1000mile/tank, that at least would be a challenge.
