Diesel Maintenance – What to Know

The demand for diesel-powered vehicles has grown alongside its advancements in technology. Drivers are starting to realize how efficient the fuel is compared to its gasoline counterpart and brands are starting to recognize and appeal to the masses. As more diesel cars continue to fill the streets, it’s important for owners to understand the maintenance requirements for diesel vehicles.

The great thing for owners that are looking to make a switch from gas to diesel is that the maintenance demands for either type is relatively similar. Of course, there are a few things that differ. As a rule of thumb, it’s important for owners to review the manufacturer’s specific recommendations for that vehicle. For those that want a general idea of the diesel maintenance service, here’s what you should expect:

Emptying Out The Water

Many diesel vehicles will have a water separator that will need to be manually removed and emptied. The reason for this component is that since diesel fuel absorbs more water than gasoline, it has a higher chance of getting polluted from that water. The water separator will collect the water from the fuel and help keep your diesel vehicle clean.

Emptying the water separator is quite easy and many people can do it on their own. All they’ll need to do is turn a little valve, called an petcock, and the user is now able to drain the water from the component.

Oil Changes

Fortunately for many diesel drivers, the service schedule for oil changes typically stays the same. Most drivers should expect their vehicle’s oil to be changed at around 5,000 to 10,000 miles. For a more accurate understanding of your cars needs, please ask for your manufacturer’s recommendations.

The only thing that’s different is in regards to diesel trucks. For trucks, they may require more frequent oil and fuel filter changes IF that truck is in a more demanding environment like towing heavy loads.

Fuel Injector Cleaning

Having the fuel injector of your diesel cleaned is crucial in the maintenance process. If you’re unsure what the fuel injector does, it injects the fuel into the cylinders at a extremely high pressure. This is what starts the engine in diesel vehicles, unlike gas-powered vehicles that utilize the spark plug system. If the fuel injector is dirty it can reduce the pressure of the injection and your engine could not start, or even break.

It’s important to know that if your fuel injector is dirty, do not attempt to clean it by yourself. In this situation, leave it to professional diesel mechanics as they have the tools and procedures to safely go about cleaning the injector.
