One week of hypermiling, and I've improved the MPG by 12 miles!
This week, I did 200 miles on 20.7 litres of fuel, which is 4.5 UK gallons.
200 / 4.5 = 44.4 MPG.
I'm astounded, I even forgot to do hypermiling sometimes, and my route is a lot of mixed villages/towns/dual carrigeways, even a few traffic jams. I'm astounded, seriously.
I think I can get 50 without even being extreme.
I've not even serviced the car completely yet (oil, leads) and I was driving around with a few sets of brake discs in the boot for half the week.
