He went on to explain further that although it is not likely that an engine with a larger displacement will ever yield better fuel economy than that of a smaller displacement at any load, the engine with smaller displacement will quickly approach that of the larger engine as these forces increase. The durability and longevity of engine life, however, will be significantly affected as this ratio increases to the point where the smaller displaced engine's lifespan is reduced significantly. Cylinder quantity and arrangement was also factored into this equation.

Have you any way of translating that for idiots like me to understand?

Right now I am getting a consistant 19.2 highway mpg solo with my Duramax. I get 18 country/city driving. Towing the Airstream it varies 13-14 mpg depending on the fuel quality and weather.

I'm pulling a 94 34' limited with a 92 Dodge Cummins. It has everything on it that Gayle Banks makes for this engine as well as a Pac Exhaust brake. Its a 4x4 with a 5 speed manual but it has a 3.54 gear. This is a wonderful choice for economy but a poor one for pulling long grades. I get 12.5 mpg pulling and 22.5 solo. I seldom run over 65. Diesels do get better mileage and I love mine.
