The Best Fuel Injector Cleaners for BMWs

Why are fuel injector cleaners necessary for healthy engine function? Over time and mileage, the fuel injectors can become clogged by the build-up of carbon and other substances. These materials come from within the gasoline and are left behind when they are not burned during the combustion process. 

After some time, this build-up of carbon and other gunk can start to harm your car’s performance. These negative effects usually show themselves in the form of sputtering during idling, trouble starting the car, or a decrease in gas mileage. Consequently, the fuel injectors need to be cleaned to prevent this type of decline in performance. That is where fuel additives like fuel injector cleaners come in. 

The BMW comes with a specific identity as a car owner. Because of that, every product or service that your BMW comes in contact with should be of the highest quality. So we combed the internet for information from product ratings and first-hand accounts of BMW owners. The result is a list of five fuel injector cleaners that live up to BMW’s standard. Here is a breakdown of each of the top five fuel injector cleaners:

1. Liqui Moly Jectron Gasoline Fuel Injection Cleaner

Liqui Moly is the brand that is most recommended by BMW drivers on BMW forums and is highly rated on Amazon. German fuel additive Liqui Moly Jectron cleans the fuel injectors and gives the vehicle better performance and drivability.

How do I know my Fuel Injectors are Clogged?

So yes, there is a lot of fuel injector and fuel system cleaning agents on the market. But, how do you know when it’s time to use one? There are several tell-tale symptoms of clogged fuel injectors. Here are the common signs:

  • Rough idling due to inconsistent fuel spray pattern. 
  • Trouble starting your vehicle, with no battery or starter issues. 
  • Decrease in fuel economy. 

Trouble starting and misfiring can also be a symptom of leaking fuel injector. If you find that your fuel injectors are not clogged but are leaking, it may be necessary to replace them. 

Can you Clean BMW Fuel Injectors?

You can clean the fuel injectors on a BMW like the fuel injectors on most vehicles. The easiest way to clean fuel injectors is to use a fuel additive similar to the five mentioned in the list above, like Liqui Molly Jectron, for example. This method is non-invasive and doesn’t require any technical know-how. Just follow the directions on the bottle and pour the additive into your fuel tank. 

A second option requires you to visit a professional to get them cleaned manually. In this process, they remove the fuel injectors and clean them, test them, and reinstall them for you. In addition, they do all of this using top-of-the-line machinery and techniques. 

How Much Does it Cost to Get Fuel Injectors Cleaned?

If you want to go the route of professional cleaning, the labor won’t be as cheap as a fuel additive. That being said, it still isn’t costly and could be worth it if you want the luxury treatment for your BMW. The total price for a car with a V6 engine should be around $100-120, but it depends on where you live and the condition of your vehicle and its fuel injectors. 

Can Fuel Injector Cleaner Cause Problems?

If you use a fuel injector cleaning product as directed by the included instructions, you will not cause any damage to your vehicle. So as long as you do not abuse the product by using it too much or too frequently, your engine and fuel systems will be just fine. 

Does BMW Fuel Injector Cleaner Actually Work?

BMW makes their own fuel injector cleaner that they sell in their dealerships and repair shops. The thing about the BMW fuel injector cleaner is that the shape of the bottle looks a lot like the bottle of the Chevron Techron cleaner that is featured as number three on this list.

The reason the bottles look the same is that they are the same product. BMW’s fuel system cleaner is a rebranding of the Chevron Techron fuel injector cleaner.

To answer the question directly, yes, BMW’s fuel injector cleaner actually works because it is the same product formula as Chevron Techron, one of the most highly rated cleaners for BMW fuel injectors. 

How Long do BMW Fuel Injectors last?

If fuel injectors are constantly under threat of becoming clogged by carbon deposits and other build-ups, do they have a shorter lifespan than other vehicle parts? According to BMW, certain fuel injectors are due to be replaced after 45,000 miles of use. However, other fuel injectors may last over 100,000 miles without experiencing any issues, especially with proper care. 

To extend the life of your fuel injectors on a BMW, or any other vehicle for that matter, stick to a good maintenance schedule. We recommend using a fuel injector cleaner every 3000 to 5000 miles. An easy way to remember this time window is to use a fuel injector cleaner every time you get an oil change. 

In Closing

A simple way to ensure that your BMW’s engine is always working smoothly is to clean its fuel injectors.
