Hello All
Over the last 12000 miles I have averaged 247 miles to a tank, mostly at motorway speeds M25/M3 & A3.
My Max distance still with 1 square showing but pump flashing was 273 mile.
I only use Sainsbury's or BP unleaded, and brim the tank to just over the filling hole.
This being on a L0 650 all in standard condition
Regards
Mark
