ya i realised that if i shift up at 2500rpms only, i can cut the
FC but quite a bit. but one thing is, some cars the fuel guage goes
up n down a bit, and the margin can be quite big… any explainations
why? one of e reasons why i like the digital fuel guage in my merc.
i can even know how much petrol to pump exactly, if i want to top
up the fuel to only a certain level.
