Excellent fuel economy

[Tappet]

.
I still say economy is based on the driver not the car, the driver can influence fuel economy either good or bad a lot more than any load can. The difference is that it's easier to blame the load or conditions rather than the driver, especially if one is struggling to attain better figures than they currently get. For those that aren't trying it's rarely an issue.

Spot on!
Unless very hilly. Weight will have little effect on economy. Drag is the biggest factor.

If I really concentrate, just for the exercise, have achieved some amazing economy, even lower than I have previously stated but it's easier said than done and a pain in the arse to drive like that and not realistic.
