Diesel engines are, by far, the most preferred option for heavy-duty truck owners and many industries. They are more durable and have the potential for a longer life span than regular gas engines.
In fact, they can last over a million miles (with proper care, of course) before requiring any repairs.
Nevertheless, using a diesel engine for that long and ensuring it serves you to its full capacity will require some strategies that must be implemented routinely. We will discuss these strategies and include tips to help your engine last longer.
Change the Oil Regularly
It is always advisable to change your oil every 3000 to 4000 kilometers because, as oil ages, it breaks down and loses its protective properties, which can cause increased wear and tear on your truck’s engine parts.
The rate at which you should change the oil depends on factors like:
- The engine’s make and model,
- Operating conditions and
- The type of oil you’re using
But in any case, the idea is to use only high-quality oils designed primarily for diesel engines and change the oil every 10,000 miles or more for modern engines with advanced filtration systems or every 5,000 to 7,000 miles for regular diesel engines. Doing this can extend your engine’s lifespan, with some estimates suggesting it can add up to 5% to the overall longevity of the engine.
Use Only Quality Fuel
Many heavy truck drivers don’t know that the quality of diesel fuel they put into their vehicles can affect their engines. Going for cheap and poorly refined fuel may save you a few bucks, but the consequence will be costlier than the few dollars you could save.
Poorly refined fuel can impact your engine’s efficiency and damage your fuel system. It is not enough to buy your diesel fuel from a reputable gas station; you must also ensure that the product they are selling is properly refined.
You should also consider replacing your fuel filter, which can help maintain the fuel system and protect it from contaminants that may clog the fuel injector and damage the engine.
Focus on Regular Maintenance
A truck requires too many things aside from its engine to work efficiently, and trying to focus on all these factors, such as brake pads, tires, gears, etc., may cause you to neglect one of your truck’s most important areas, the engine.
This is why regular and scheduled maintenance must be a “thing” for you. Create a regular maintenance appointment with an experienced mechanic so they can inspect everything at once and resolve any issues.
This doesn’t have to happen only when your truck develops faults; you can also detect them through preventive maintenance before they become problematic.
However, if your truck’s diesel engine is faulty and you plan to change or fix it, don’t just use generic parts, especially if you want the repair to last longer. Ask your mechanic for suggestions on reliable brands like Cummins.
Caterpillar parts are reliable and will ensure your diesel engine works efficiently for years after the repair. While generic parts, though cheaper, could develop faults just a few months later. So you must not only factor in the prices but also the quality and reliability of parts you’re using to repair and maintain your truck’s engine—that’s the only way you can guarantee it will last long.
Change the Air Filter When It’s Dirty
Air filters are just as important as fuel filters in a diesel engine. They prevent dust, dirt, and other particulates from entering the engine and causing excessive wear or damage.
So, you must change them as soon as they get dirty; otherwise, it will make your engine work harder, generate heat, and consume more fuel for average performance.
If care is not taken and a dirty filter is left on for a long time, it will eventually damage the entire engine because its role is to allow clean air to enter the engine for a complete “combustion” process.
But if they are dirty, the amount of air that goes to the combustion chamber will be reduced, which may result in what many studies describe as an imbalanced air-to-fuel ratio.
An imbalanced air-to-fuel ratio means that your engine will run “rich” and burn more fuel than air in the combustion process, thereby increasing the engine’s temperature and gradually damaging its parts.
So, the main message is to observe your air filter at least every 15,000 miles and replace it if necessary to protect your diesel engine.
Wrapping Up
While diesel engines may be cost-efficient, they require care and maintenance to stay active for as long as you want them to. Neglecting to maintain them frequently will reduce their durability and even increase the repair costs if they break down. So take these tips seriously and make those engines work their worth.
