There is no comparison between a gas engine and a ultra high compression diesel engine and especially a newer engine with a DPF that requires regen cycles. My 2011 2500 Duramax is not providing optimum fuel economy until I have driven at least 30 miles down the freeway. My 2007 Prius is providing 45 MPG as soon as I leave my driveway.
A little knowledge is often too little to be of any value. Or to paraphrase the great Yogi Berra, it is not what you know but what you know that ain't so that causes problems.
