The 20mpg sounds a bit unrealistic.
Not in any way fact, the diesel will outperform a gasser in every aspect. Mileage, power, torque, hills, straightaways, etc, etc. I have tried to convince myself in the past that a gasser will keep up and it would flat out get beaten in every catagory. I ran 3/4 small blocks, 3/4 Big blocks, and they would get smaller in the rearview mirror. Now if a person wants to rev the living piss out of their gasser you could stay in sight, but you will end up in the shop sooner than later for repairs. While the almighty modern technology diesel will still only need an oil change. Your quote is a phrase that people that dont have try to convince themselves but are dead wrong. Been there done that. For those that dont believe me load up, and you will get smaller in the rearview mirror. Not trying to piss anyone off or say you cannot tow with a 1/2 ton gasser, but just preaching the way it is.:corn:The deisels will leave the gassers on the hills but the gasser will take the straights. We are talking stock power plants.
