*-> 12-month fuel cost estimate based on average price of regular unleaded and average price of diesel, fuel tank capacity, and a yearly maximum of 15,000 miles. Regular unleaded price used, $2.60 and diesel price $3.15. Based on15 mpg, towing not factored in mileage.

Besides the side-by-side comparisons of price, power, and towing, other factors in the equation include wear, aftermarket potential, and mileage.

With a gasoline-powered truck, even in the heavy-duty lineup, most drivetrain parts, including transmission, cooling system, driveshaft, rear end, bearings, and brakes, are of lesser strength than the comparable diesel counterparts. On the flip side, diesel trucks do weigh more than gas-powered trucks and do take longer to slow and come to a stop. Stopping is crucial with larger trucks, especially when towing and with several manufacturers offering trailer brakes as an option, diesels may have a slight advantage with their heavy-duty original equipment.
