Grins per mile are far more important in a Mog.
Yep, when people ask me the MPG I say that I only measure SPG, blanks looks then I explain Smiles per gallon.
I probably get somewhere between 20 and 25 MPG but have never bothered to calculate it. If I did and it was my daily drive it'd probably scare me.
Son-in-law has just bought a secondhand Maserati, doesn't know what the MPG or running costs will be and doesn't care (until its first service probably)
