Attempting 837 miles on one tank in one day

Next Monday, I’ll be taking my 432k-mile Octavia on a road trip to see if it’s possible to hypermile all the way from London to the Nurburgring, do a lap, and drive straight home, a total of 837 miles in one day…the tank holds 12.1 gallons / 55 litres, so I need to hit 70mpg (UK) / 58mpg (US) / 4l/100km.

Any hypermiling advice or useful things I should take to relieve the boredom?
