3 Ways to Misunderstand Your Diesel Engine

Whether or not you are new to trucking, you already know that there is a clear difference between cars and large commercial vehicles. In particular, semi-trucks run on diesel engines, which have their differences and similarities to a standard car engine. There has been a lot of misinformation about how to treat a diesel engine, and this post will help to clear up the three biggest misunderstandings.


In standard vehicles, the best way to tell whether the engine is warm is by checking the coolant temperature. Therefore, it is common to incorrectly assume that the same goes for a diesel engine. But diesel engines are built with a larger capacity; this means that even when the coolant is at a high temperature, the engine itself may still need to warm up.

Engine Wear

When it comes to warming up diesel engines if people make the mistake of driving right after starting the engine. If you’re new to diesel, then you might be surprised to know that most of the wear to a diesel engine occurs when you start it and not while it is running. This is because it takes a longer time for the oil in a diesel engine to get flowing. The best way to reduce engine wear is by waiting at least a few seconds after starting the engine before driving so that it can warm up properly.


Lastly, a misunderstanding on the opposite end of the spectrum is that to keep a diesel engine from going cold, you need to keep it idling. But the truth is that, even though idling doesn’t burn a lot of fuel, it will put much more wear on your engine than if you turn it off, restart it, and let it warm up. Also, idling will generate unnecessary fumes, which adds to pollution.
