It handles large loads—like a 16,000 lb fifth-wheel—effectively, though users note it lacks the high-torque "grunt" and exhaust braking of engines like the 6.7L Power Stroke.
This is a notable trade-off. Expect roughly 8–10 mpg while towing and 12–14 mpg unloaded, regardless of the load's intensity. Reliability Concerns 7.3The Big Short
Some speculate that low oil pressure at idle (as low as 8 psi by design) may contribute to these failures. It handles large loads—like a 16
