Cleaning Diesel Fuel Injectors: What You Need to Know

Cleaning Diesel Fuel Injectors: What You Need to Know

If you drive a diesel, you have a little bit of extra maintenance that you don't have with gas vehicles. Diesel, because of the nature of the fuel, builds up more deposits on the injector tips than regular gas vehicles. Those injector tips must be cleaned, or your vehicle will be sluggish, and your gas mileage will decrease. However, if the tips of the injectors are worn, no amount of cleaning is going to help them. Once deposits build up, the spray from the injector is no longer even, which could cause a misfire in the cylinder. Here's what you need to know about cleaning your fuel injectors.

Cleaning Fuel Injectors

A professional garage uses an ultrasonic machine to clean the injectors. This is the best way to ensure that the injectors are thoroughly clean. While you could take the injectors apart and clean them by hand, that method is not advisable unless you are familiar with the process. You may also clean the injectors with additives, but they are not always reliable.

Cleaning the Fuel System

In addition to cleaning the injectors, additives will also clean the rest of the fuel system. Even if you bring your vehicle to a shop to have the injectors cleaned with the ultrasonic machine, you may want to use some additives as they provide additional benefits, including:

  • Cleaning the pipes

  • Cleaning the fuel pump

  • Cleaning the injector pump (if applicable)

These areas also build up deposits. Keeping the system cleaned and maintained allows the entire fuel system to last longer. The additives also provide extra lubrication along with the fuel, which makes the engine last longer.

If your vehicle is not getting the performance it once did, you could have dirty or worn injectors. However, if the injectors are worn, no amount of cleaning is going to fix that problem. You'll have to have the fuel injectors replaced.

Fuel Quality

Fuel quality plays an important part in the cleanliness of the fuel system. Since diesel is already less refined, if you have poor quality diesel, you'll have more trouble with deposits forming on the injectors and throughout the fuel system. Keeping the system clean between professional cleanings is beneficial for the vehicle, the atmosphere and your pocket.

Also, if you have fuel with water or dirt in it, it could change injector spray pattern. Once that happens, the injectors will need to be cleaned. In rare cases, where dirt may have damaged the injector, the injector may have to be replaced. Since replacing fuel injectors is usually expensive, the first step is to try cleaning them.

Dirty vs. Worn Injectors

If your vehicle is not getting the performance it once did, you could have dirty or worn injectors. However, if the injectors are worn, no amount of cleaning is going to fix that problem. You'll have to have the fuel injectors replaced. Worn fuel injectors will do the same thing as dirty fuel injectors — it could make the engine misfire.
