Aren’t you based in the US? If so isn’t your fuel consumption about right based on fact your US gallon is smaller than UK gallon (therefore you would cover less miles)?
Yes...I live in Oregon.
....and I did not know this about the volume difference in gallons before.
Our gallon, yes, is 128 oz/3.78L.
Now I see why my mpg is always less than what you all post.
Based on your gallon/4.54L and the MFD/2 average MPG is 29.7 (US)...its MPG (UK) is 35.6 right now.
My concern has only been for the initial comparison to the K04 tune-MPG on mine. Initially, with the K04 upgrade in 2010, it was easy to keep it between 28 and 29 MPG (US). Over the years this dropped...sometimes I had trouble keeping it above 23 MPG. All of the fueling bits I replaced in 2020 and the turbo in 2021...plus going back to my original GIAC K04 tune and reinstalling a Cat to the DP; got me feeling I was close to restoring the MPG as I was able to achieve an average of 25 and 26 mpg (US). Feeling much better about it now. Because I was at one point thinking its cam timing had a lot to do with the MPG. But my cam timing's phase position is just -2° warmed, and ignition timing data never reveals itself to be out of wack.
