Diesel vehicles, common in trucks and some SUVs, offer better fuel economy and strong towing, but they cost more to buy and can cost more to maintain. Whether a diesel makes sense comes down to the complete monthly cost at your actual usage, not just the better fuel economy that diesel is known for.
The Diesel Fuel Advantage
Diesel engines are typically more efficient than comparable gas engines, especially under load, which lowers the fuel portion of the complete monthly cost for high-mileage drivers and those who tow. Diesel fuel pricing varies relative to gas, so the advantage depends on local prices as well as efficiency.
The Diesel Cost Premium
Diesel vehicles usually cost more to purchase, raising the payment, and some maintenance items, like fuel filters and emissions systems, can cost more. These offset part of the fuel savings. The complete monthly cost is where the higher payment and maintenance meet the fuel savings, and the result depends heavily on mileage and towing.
Who Benefits From Diesel
- High-mileage drivers and those who tow often see diesel's fuel savings outweigh its premium.
- Low-mileage drivers may find a gas vehicle has a lower complete monthly cost.
- Account for diesel's higher purchase price and some pricier maintenance.
- Compare the complete monthly cost at your actual usage to decide.
