Guys, I live in the midlands and I'm planning my next trip to Northumberland. Route planners send me either the M1 or the M6 and the distance difference between them is not much. Now, if I take the M6 and even the toll I can probably optimize fuel comsumption,
but I guess the M1 and other A roads could require a bit more fuel, but topo maps show that route is less hilly which will improve mpg. Any recommended route?
