When it comes to raw power and reliability, diesel engines are in a league of their own. At Gearhead Engines, we’ve spent decades remanufacturing and perfecting diesel powertrains — but beyond torque and horsepower, there’s a fascinating history and plenty of little-known trivia behind these workhorses. Here are some fun diesel facts every gearhead should know.
1. The Diesel Engine is Named After Its Inventor
The diesel engine was invented in the 1890s by Rudolf Diesel, a German engineer who wanted to create a more efficient engine than the gasoline options of his time. His design went on to revolutionize transportation, industry, and shipping worldwide.
2. Diesel Engines Were Originally Meant to Run on… Peanut Oil
That’s right — Rudolf Diesel envisioned his engine running on alternative fuels like peanut oil. Today, this idea lives on in biodiesel technology, which uses renewable plant-based oils as a sustainable fuel option.
3. Diesel is the King of Torque
Gas engines are known for higher RPMs, but diesel engines dominate when it comes to torque. That’s why you’ll find them powering heavy-duty trucks, buses, ships, and construction equipment — they deliver the pulling power that gets big jobs done.
4. Diesel Engines are Built to Last
While gasoline engines often retire after 150,000–200,000 miles, well-maintained diesel engines can run for 500,000 miles or more. That longevity is why investing in a remanufactured diesel engine is such a smart choice.
5. Diesel Powers More Than Just Trucks
When you think diesel, you probably think of pickup trucks and semis. But diesel engines also power locomotives, ships, farm equipment, military vehicles, and even some passenger cars.
6. Modern Diesel Engines Are Cleaner Than Ever
Thanks to advanced emission systems and ultra-low sulfur diesel fuel, today’s engines produce far fewer pollutants than their predecessors. Add in biodiesel compatibility, and diesel is greener than you might think.
7. Diesel is More Efficient Than Gasoline
Diesel contains about 10–15% more energy per gallon than gasoline, making it more fuel-efficient. That efficiency, paired with engine durability, is why diesel engines are still the top choice for hauling, towing, and long-distance driving.
Final Thoughts
From their quirky peanut oil origins to their reputation for brute strength and durability, diesel engines are full of fascinating history and engineering brilliance.
