When it comes to durability, engines that are simple, well-built, and not pushed to their absolute limits tend to last the longest. Here's what stands out in my experience:
-
Inline Engines (Straight Engines): Inline-4s and Inline-6s are renowned for their balance and reliability. The Inline-6, in particular, is a favorite for its smooth operation—think Toyota’s 2JZ or BMW’s legendary straight-six engines. They’re sturdy because there’s less stress on the components compared to more compact designs.
-
Naturally Aspirated Engines: Engines without turbochargers or superchargers tend to last longer because they don’t deal with the extra heat and pressure that forced induction brings. Look at Honda’s naturally aspirated engines—they’re simple, efficient, and known for racking up hundreds of thousands of miles.
-
Pushrod V8s: While modern overhead-cam designs are often more efficient, pushrod V8s, like Chevy’s small-block engines, are low-revving workhorses. They’re robust, easy to work on, and built to last, especially in trucks and muscle cars.
-
Diesel Engines: A well-maintained diesel engine is practically bulletproof. Their low RPMs and high torque make them perfect for heavy-duty applications. The 7.3L Powerstroke from Ford or the Cummins 6BT are prime examples—they’re overbuilt and designed for longevity.
-
Boxer Engines (Flat Engines): Subaru and Porsche are famous for their boxer engines. Their low center of gravity is great for handling, and while maintenance can be tricky, they’re known to go the distance if cared for properly.
At the end of the day, durability also comes down to proper maintenance. Even the best engine won’t last long if you skip oil changes or ignore small issues. As always, following the specs and procedures from a reliable service manual is your best bet to keep any engine running strong for years to come not matter the type.
