Big Short — 7.3the

Some 2020–2022 models experienced premature metal failure in the lifter rollers, which can destroy the camshaft and require a full engine replacement.

Some speculate that low oil pressure at idle (as low as 8 psi by design) may contribute to these failures. 7.3The Big Short

For those who want a capable workhorse without the complexity of DEF or DPF systems, the 7.3L is highly regarded, though it requires a tolerance for high fuel costs. Performance & Capability This is a notable trade-off

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. It handles large loads—like a 16

The , introduced in 2020 for Ford’s Super Duty lineup, is often praised as a reliable, lower-maintenance alternative to diesel for heavy-duty work. Designed for durability over high-tech complexity, it uses a cast-iron block and overhead valve (OHV) architecture to simplify repairs and reduce potential failure points common in modern emissions-heavy diesels. Performance & Capability

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

While marketed for its longevity, some early owners have reported significant internal issues:
