Duramax Diesel Engines (Advantages and Disadvantages)

(Updated on April 21, 2020)

Diesel engines are like gasoline engines because they both have internal combustion chambers. The only difference is that diesel engines do not require a spark to ignite the air and fuel mixture. When the air itself gets exposed to the fuel, this will cause an ignition without needing a spark. However, this does not mean that every diesel engine brand performs the same. There are some diesel engine brands that are preferred over others. The Duramax diesel engine is a good example of this. This is a V8 diesel engine which comes from General Motors and is made specifically for trucks.

Duramax is a diesel engine product line that is synonymous with quality. You’ll find their engines in everything from small pickup trucks to bigger hauling trucks. When you choose a Duramax diesel engine for your vehicle, it is important to consider what you’re using the vehicle for. Something that might be an advantage to one person may not mean all that much to another person. So, take that under advisement when you look at the following advantages and disadvantages of the Duramax diesel engine.
