Actually, I'm not convinced that driving a cold engine with a light foot will make much difference. It could be argued that the engine takes longer to warm up, so therefore a heavier foot might work counter to common-sense. It depends on the fuelling map as to how the engine performs when cold. With a carburettor (they don't have "lean-burn" regions) in my experience it would not make any difference on a cold engine, except high rpm and very wide throttle openings.danny35 said:Thanks for the reply. I wouldn't mind 20mpg so much, but it includes me driving with a light foot and with minimal traffic. I dread to think of the MPG when I drive more spiritedly and get caught in normal traffic. I was hoping for 25mpg on this tank and 20mpg driving more spiritedly with normal traffic.
Maybe try filling up again now, make a note of the litres and miles, then reset the trip meter and try a bit more right foot to see if it makes no difference.
I've also had another look at the list in your initial post, here it is again ....
- Clean MAF sensor & EGR
- Calipers (though I think they should have been checked already)
- UN-metred air in the system
- 02 Sensor
- Clean throttle body/sensor
- Wheel Allignment
- Tune up
- Pipes for damage
- Air filter connection hoses.
When was the last time that these were checked (these also likely to affect mpg)
- spark plugs
- valve clearances
