Fuel consumption too low!!!
Well its not a problem, it's just bugging me!
I was getting as low as 21mpg till i replaced the thermostat earlier this year, then always got somewhere in the 27's.
The last 3 times i have filled up I have got 33mpg! What's going on?
I still drive like crazy, same mix of urban/motorway/rural, use the same fuel, and the only thing i have done since the thermostat is clean the idle actuator to cure rough tick-over / cutting out (it worked - but it didn't change the mpg straight away, not that one would expect it to).
The only other variable is I suppose, lower September temperatures, but with the thermostat okay surely this wouldn't have an effect.
Don't get me wrong, i am not complaining about 33mpg (i didn't actually think the 1.8 would be capable of over 30, anway), but what is the explanation?
