🚚 Gas vs Diesel — Which Should You Choose?
Gas Engines (6.8 L & 7.3 L):
- Lower initial purchase cost.
- Easier maintenance and no DEF fluid.
- Better for light-duty fleets, contractors, or homeowners.
Diesel Engines (6.7 L & HO Diesel):
- Superior torque for towing and long-distance hauling.
- Improved efficiency under heavy load.
- Longer engine lifespan with proper maintenance.
If you consistently tow over 15,000 lbs, the diesel engines are the clear choice. For moderate towing or everyday driving, the 7.3 L gas offers plenty of strength. You can compare diesel and gas advantages.
