Thanks, I try to drive at 55mph as my manual says to keep the car between 2000 and 3000 revs for maximum efficiency, and at 60mph my car is on the 3000rev marker. However, sometimes I do 80-85 if I'm in a mad rush, and I think the car does guzzles through it at this speed.
Is this true:
Drive from A to B at 55mph will use less fuel than A to B at 70mph? Even though driving faster gets you there quicker?
