Re: What's your car's Fuel Efficiency Hi all, I have been off this site for a long time, but just remembered today after getting an e-mail from the mods about the B'lore meet. So just want to update my FE figures. At the end of every month, I refuel a full tank of diesel so that I get an accurate mileage figure for each month. From the attached FE figures, one thing for sure that the mileage has increased a lot after 1st service. And I'm very happy with it.
