Mine is only at 1800 miles and I am avg 20.9MPG
One thing we all need to keep in mind is the fuel.
Not so much the octane, but the mix.
If it is the 10% ethanol mix it will lower the MPG....some cars by as much as 10%.
My wife's MINI hates
the ethanol mix.
So for max MPG......stick with pure gasoline.
