The difference between the average vehicle and a semi-truck is the design of the engine. Semi engines are six times the size of a standard car engine and designed to last a long time. In fact, the engine of the average semi can withstand over a million miles in its lifetime. If the motor is fitted with a power take-up, it will endure even more wear and tear.
Diesel fuel is an important factor for semi-truck longevity because it is lighter than gasoline, and due to its chemical makeup, it packs more energy. Engines that run on diesel last much longer than their gasoline counterparts because of their mode of operation. Where a gasoline engine will run between 2,000 – 3,500 RPM, diesel-fueled engines work at a much slower rate – 1,300 to 1,600 RPM. This is an important advantage for engines that run for hours at a time.
Diesel engines are built for longevity and power, and they are how 18-wheelers literally do the heavy lifting for our commercial infrastructure. The key to maintaining this longevity is preventive maintenance from a trained professional. This is where White Tank & Truck Repair can provide the most value. Preventative truck maintenance can be the difference between replacing a $10 part and paying thousands more to repair a broken-down truck or trailer.
