Got petrol today so lets crunch some numbers.

First finding my MPG to compare to - so i am going to use the 3 runs prior:
1. 27.86 mpg uk - 98 miles
2. 28.23 mpg uk - 99 miles
3. 28.06 mpg uk - 98 miles

Distance: 295 miles
Average MPG: 28.05 (UK) or 23.36 (US) or 10.07 litres per 100km

So now onto my results for my first run with effort put towards efficiency -

Distance: 137 miles (the first 30 - 40 of these miles were my 'regular' driving style)
MPG: 30.07 (UK) or 25.04 (US) or 9.39 litres per 100km

MPG improvement: 7.2% or 2.02 (UK) or 1.68 (US)

Thoughts!

Not too shabby for a first attempt imo - particularly as i was not 'eco' for the whole run (i will be this time). Whilst 1.68 US mpg does not sound that great - 7.2% does in my mind...

Plan:

continue with the driving style
try and fix my lack of vacuum advance + check timing - i think that's causing a big loss!. (probably wont be sorted this run - but for the next one.)

next run target:

10% improvement from 28.05 mpg UK (30.86 mpg UK)

What do you guys think?

EDIT : my 'distances' are very accurate - i have seen most modern cars that display higher speed than actual speed (and therefore higher mileage) - when my car says it is doing 30/40/50 or whatever mph - GPS agrees with it - it can be perhaps 1mph out...
