Have you ever wondered about the consequences of downshifting a diesel engine too soon? Or maybe you’re curious about which diesel trucks are the most reliable for 2025? In this post, we’ll explore these topics along with some engaging insights specifically focusing on diesel engines that every car enthusiast should know.
When it comes to diesel engines, they often offer impressive torque and fuel economy, especially in the full-size truck segment. However, enthusiasts must also be aware of the risks involved in mishandling these powerful machines. For instance, one common mistake among manual transmission drivers is an improper downshift, especially at high RPMs—a practice known as a "money shift."
The Dangers of Money Shifting in Diesel Engines
Recently, a YouTube video showcased what happens after a Volkswagen TDI engine suffered from a money shift, leading to catastrophic damage. The disassembly of the CKRA 2.0-liter four-cylinder common rail turbodiesel engine revealed severe destruction, including holes in the engine block and shattered internal components. The term "money shift" describes the situation where a driver inadvertently downshifts into a lower gear while driving at high RPMs—an action that can cause the engine to over-rev and fail.
In this particular case, the damage was substantial enough to lock the crankshaft, rendering it useless. Surprisingly, while many engine components showed signs of excellent maintenance, it became clear that the money shift had wreaked havoc on the system. This situation serves as a cautionary tale, emphasizing the need for drivers to fully understand their vehicle’s mechanics before engaging in spirited driving.
