Thanked 1,522 Times in 1,123 Posts in Tucson, AZ, the diesel-to-gasoline cost ratio is 1.28:1 [$4.059(d) / $3.179(g)], so in order for diesel to come out "ahead," it had better get 28% better fuel economy than its equivalent gasoline-powered counterpart...which means >51MPG!

...and, that's NOT considering any other cost "uppers" such as the higher "going-in" cost of the diesel engine versus the gasoline engine.
