Diesel injector cleaner

 Your car relies on fuel injectors to relay the diesel to the engine. With all the dust in the air and the small particulate in diesel, these injectors take on debris. The gunkier they get, the more your engine struggles. If left unchecked, this impacts the fuel efficiency of your vehicle, but in the worst-case scenario, your engine could get damaged from overworking itself. You risk many performance issues, from stalls to accelerating without a diesel injector cleaner.

 Instead of taking that chance, you can apply a diesel injector cleaner to address the buildup. An essential part of preventative maintenance, the quality of the cleaner dramatically impacts its value. So, to save you some legwork, we’ve tracked down the best diesel injector cleaners available today.

Different Types of Diesel Injector Cleaning

Chemical Agents

It is the most popular type of diesel injector cleaning. It uses several chemicals to remove the water and flush out the debris. These cleaners use polymers, which can vary in strength depending on their formula. Removing carbon deposits in diesel is essential, but many recipes also add additional additives.

A quality cleaner will contain a conditioner that regulates the sulfur content to stabilize the fuel. These cleaners work well when used in conjunction with a regular maintenance program. These cleaners are also the most cost-effective and accessible.

Ultrasonic Cleaners

The ultrasonic cleaner is a more sophisticated approach than diesel injector cleaners. Soundwaves are used to remove debris. It takes about an hour. This involves eliminating injectors from the engine and running them through an ultrasound system.

This method is excellent, but it needs the benefits of chemical treatment. It doesn’t lubricate and requires more time and work. It is only worth it to spend the time and money repairing diesel injectors in large quantities if you’re working with many of them.

Rail-Induced cleaners

This type of cleaning is only done in mechanic shops due to the amount of work involved. It works but is only used after chemical cleaners have been tried. A high-pressure washer is used to remove the debris physically.

Depending on the flow rate, it can be a problem for the filter baskets, but it does remove the gunk. This solution should only be used when all other options have failed. It is usually quite expensive and can easily be avoided using a regular cleaning agent.
