Just go careful, i drove from Dartford to NW Germany through France, Belgium and Holland. Nowadays engines have been tested with far more tolerances than we can do to our cars. I picked up on 17th Oct i now have 998miles on the clock and i am currently in Garmisch in Bavaria. This afternoon im off to Innsbruck and a little drive on the Brenner Pass!
I sat at 160Kmh on cruise all the way down here, 402miles on one tank.
Just enjoy it!!
