Think outside, no box required.
Usually less mpg for gas or do you mean equivalent miles taking into account cost?
Doo states he can get 205mi for 13gal of gas so that's roughly the equivalent to 24 mpg.
320mi from 81litres/18 gallon petrol tank so thats around 17mpg
But as you point out gas does tend to get less MPG.
And you lose some power
So i dunno..
Is it worth it?
probably not.
