Things to Consider Before Buying a Diesel Injector Cleaner

If you're buying a diesel injector cleaner for the first time there are a few key criteria you should keep in mind. Your diesel injectors will likely need cleaning if you’ve noticed a lack of power, but there are other warning signs as well. These can include rough running, poor gas mileage, and failed emissions tests. If you've decided to clean your injectors, then consider the following:

High-Pressure Common-Rail Diesel Engines

High-pressure common-rail (HPCR) diesel engines are commonly found in modern vehicle applications, and often deliver better power and efficiency than conventional systems. However, they require different additive treatments. This is because of the high temperatures that come with highly-pressurized systems. With this in mind, if your car or truck has a common-rail diesel engine then it’s best to select a diesel injector cleaner that caters to this.

Extra Additives

When selecting a diesel fuel injector cleaner, it pays to take note of the other attributes that are bundled with it. This can include everything from fuel neutralization to cetane increasers. Some additives have added lubrication for vehicles that require high-sulfur content, while others fight against corrosion by displacing any traces of water.

Concentration

Some diesel injector cleaners come highly-concentrated, with one bottle able to treat up to 400 gallons of fuel, whereas others may only be enough to treat one tankful. Consider the cost to usage ratio of each, and whether you want to use your diesel injector cleaner regularly.

Frequently Asked Questions

Why do Injectors need cleaning?

Diesel injectors are what spray fuel into the engine cylinder just before combustion. But combustion often leads to carbon deposits building up over time. If you've ever seen soot in your tailpipe, this is one example of carbon build-up.

What are the symptoms of a dirty diesel injector?

Carbon build-up within your engine, and particularly on the injectors, may lead to the injector’s spray pattern becoming blocked and irregular. This can reduce power, harm fuel economy, lead to premature knocking under load, and reduce your engine’s smooth running—even at idle

How often should I clean my injectors?

It often depends on a variety of factors, including your driving habits and the quality of diesel in your area. However, a good rule of thumb is to clean them at each service, adding some diesel injector cleaner additive to a full tank shortly afterward. Alternatively, a preventive measure may be to use a broader-spectrum additive regularly, at each fill-up.

Can I use iron-remover instead of wheel cleaner?

It’s not recommended to use more than the stipulated amount of diesel injector cleaner. On each product can or tin the ratios will be printed. An easy way to know the correct ratio is to know your car or truck's fuel tank size. When filled up you can then add the correct quantity of diesel injector cleaner. One notable exception to this rule is Sea Foam, adding more than the minimum ratio will not damage your engine, but maybe wasteful.

Wrapping Up

There’s a mind-boggling amount of diesel injector cleaners on the market, but as this guide will have made apparent, there are many differences between each. While many of the options in our list will clean your car or truck's diesel injectors quickly and effectively, many other unique attributes differentiating each from one and other. While each is different, the best product for you will likely come down to considerations such as price, concentration, and application.
