The battle between Cummins, Duramax, and Power Stroke diesel engines has raged for decades—but most comparisons focus on specs and sales pitches, not the technical differences between these engines.
In this video, I break these engines down from an engineer's perspective to what actually makes these engines different—based on real use, hands-on repairs, and a deep understanding of how these engines work under load. No brand loyalty here—just facts, experience, and practical knowledge you won’t get from the manufacturer brochures.
This video isn’t about picking the “best” diesel truck engine — it’s about helping you understand how they’re built, how they perform, and what that means for real-world towing, RVing, and long-term ownership.
💥 Thanks to Our Sponsor! – Power Service Diesel Injector & DPF Flush
We’ve used Power Service products for years to help keep our diesel engines clean, powerful, and efficient. Their new Diesel Injector Cleaner made a huge difference on our old backhoe and we have run it through all our on road engines.
