Not a flippin' clue, ...really doesn't concern me either.
I only do low mileage each year as work is very close to where I live so that helps keep the miles down. I've always gone for performance cars and honestly have no interest whatsoever in mpg.
Poor mpg is just a part of owning a performance vehicle imo.
Sure it would be nice if my car did 50mpg but I fill up usually every week regardless.
Yes love that attitude
Also worth mentioning that since I've changed the fuel injectors & the fuel system even my Zed hasn't a clue what mpg it's doing.
Think it's because part of the standard way it works out the mpg is off fuel injector cycle.
Oh well never mind, ..if I had wanted economical I'd have bought a Prius.
Miles per gallon - who knows
Smiles per gallon - LOADS
