Diesel engines of today have become synonymous with high power, efficiency and a lower cost of operations. As such it should be no surprise that more and more people are looking towards using diesel powered vehicles for their day-to-day travelling and work. But like all engines, wear and tear from constant use is an ever present concern. To make sure your diesel engine keeps humming and working at top efficiency for decades to come, you need The Best Diesel Injector Cleaner on the market today!
In this article, we’ll be looking into the best diesel fuel treatments available, as well as explain why they’re needed.
While diesel engines operate on a different principle than regular gasoline engines, many of the issues remain the same.
Even the highest quality fuels are far from pure. Small mineral deposits left over from processing will be left in the injection system of your engine. Over time, this can cause a buildup that can disrupt the proper flow of fuel and cause performance and efficiency issues. Once the fuel enters the combustion process, the burn is never 100% complete. While most of the left-overs are expelled safely through exhaust, tiny particles can negatively affect the various engine components, of which there are many.
The best diesel injector cleaners help to lubricate the fuel to minimize any mineral buildup in the injection system, as well as optimize the combustion process, resulting in a more thorough burn that increases performance, fuel mileage and reduces the amount of left-over particles. Diesel fuel system cleaners make sure the engine operates smoother and has a longer lifespan as a result.
Our list for the Best Diesel Injector Cleaner are as follows:

#2 – Liqui Moly Diesel Purge
If Lucas weren’t so good at what they do, Liqui Moly would certainly take the top spot here otherwise. Now, while some true blooded Americans might not feel fully comfortable endorsing a German company, I would take the time to remind everyone of the amazing qualities of German engineering. These guys know their cars, their engines and their engine and fuel products. Liqui Moly is a global brand with overwhelmingly positive reviews across the board.
Their Diesel Purge product is without a doubt one of the best diesel fuel treatments on the market today. It’s designed to clean the injector nozzles and the combustion chamber from any deposits, and it increases the fuel cetane rating – which essentially refers to the fuel’s combustion quality. It helps remove issues like engine knocking, and guarantees a smoother performance across the board. It also protects the engine components from corrosion, and optimizes the emissions values. It’s suitable for engines with or without diesel particulate filters and is fully tested with turbocharged engines as well.
You’re also completely safe to use it as a purely preventative measure. Adding a small dose every now and again will make sure your engine never even develops any issues in the first place.
I tried to find any negative reviews but those barely amounted to 1% of the total review counts. This product just does not disappoint. Without a doubt it is one of the best fuel injector cleaners for diesel engines. Period.
#3 – Power Service Diesel Kleen + Cetane Boost
Good ol’ “Made in Texas” takes this spot. For over 60 years, Power Service has been working on ways to treat diesel and make it better in every way imaginable. This gives them a leg up on many other companies who spread their efforts too thin. Power Service on the other hand owns a huge 42 acre chemical storage and research facility in Weatherford, Texas and is putting in non-stop work every day.
Their Diesel Kleen product boasts some truly impressive claims. It cleans injectors, lubricates the entire fuel line as well as boosts cetane rating to deliver that truly optimized performance. This product works for diesel engines sporting the latest technology – such as the High Pressure Common Rail (HPCR), as well as any older systems. Cetane rating is boosted by up to 6 numbers. It also contains Slickdiesel® Lubricator, that makes sure the fuel pumps and injectors are kept completely safe even when using Ultra Low Sulfur Diesel (ULSD).
Diesel Kleen is also completely compatible with all the different diesel fuels like ULSD, Biodiesel and any Biodiesel Blends. Is it the best fuel additive for diesel cars? Definitely in the top #5.
#4 – Hot Shot’s Diesel Extreme
Owned by parent company Lubrication Specialties Inc. (LSI), based in Mt. Gilead, Ohio, Hot Shot’s is focused around producing high performance enhancers for primarily diesel engines and fuel systems. Whether the end user owns a pick-up truck, a tractor or a whole fleet, Hot Shot’s products are meant to solve the biggest issues plaguing these engines.
The Diesel Extreme, as the name implies is meant for Diesel engines only and it’s got some nice power under the hood. It’s designed to restore power and performance to any engine already suffering from issues, as well as act as a preventative to any others. The product restores throttle response, helps to eliminate black smoke and makes it easier to cold start the engine. It also reduces DPF Regeneration Cycles by up to 50% – meaning your filters are under less strain, and are likely to have a much longer lifespan and fewer regeneration issues overall.
Diesel Extreme of course also focuses on cleaning the injectors and the whole fuel system as well as the gas tank. Fuel mileage is also increased, while stiction is notably reduced. It claims to have the highest cetane rating boosting power of any product on the market. It’s features like that which earn you a spot on the top #5 list for the best diesel injector cleaner.
#5 – Stanadyne Performance® Formula Injector Cleaner
With a history spanning more than 140 years, Stanadyne products are probably familiar to everyone. These days, Stanadyne focuses on producing and selling fuel injectors and fuel pumps, and has sold off their Fuel Additive branch. However, the additive brand still lives on and is highly respected by users everywhere.
The Performance® Formula cleaner boasts many of the same features as its competitors. A focus on cleaning the injectors and the whole fuel system from IDID’s – Internal Diesel Injector Deposits, be they from the common rail type engines or any other type. The cleaner also contains lubricants, as well as the cetane booster for better fuel combustion and a smoother operation all around. It truly deserves to be on the top #5 list for the best diesel fuel additive for cleaning injectors.
The product also comes in many varieties depending on the environment conditions of your location.
I hope this article on the Best Diesel Injector Cleaners has given you all some good insights and set you on your way towards your next purchase. I’m sure your diesel powered vehicle will thank you!
