Top 3 Best Diesel Fuel Injector Cleaners

Just like regular gasoline engines, diesel engines experience carbon deposit, varnish, and engine gumming issues. The truth is that both gasoline and diesel fuel are made from the same crude oil base. The difference between them is that diesel fuel is made from the denser and heavier parts of crude oil than gasoline, thus requiring high levels of compression within a cylinder to ignite the diesel without the use of a spark. Gasoline on the other hand, is highly volatile, lighter, and much more flammable, and powers engines through the use of spark ignition. Diesel isn’t designed to be directly flammable through spark, and thus it requires a special compression cylinder for combustion.

Diesel has its own unique fuel combustion characteristics, which differ from gasoline. Combusted diesel leaves different types of fuel deposits, tar, and residue that require fuel treatments in a different way than gasoline engines do.

In this article, we’re going to be reviewing the Top 3 Best Diesel Fuel Injector Cleaners, as well as give you helpful information as to what engine improvements you can expect to see through using them.


1. BG244 Diesel Fuel System Cleaner 11oz can

BG244 is leading the way to help you achieve a higher level of performance from your diesel engines. Great for truckers, work trucks, and truck enthusiasts, the BG244 Diesel Fuel System Cleaner 11oz Can will immediately bring “new life” to older engines, and also allow you to maintain diesel engines that are just a few years old in order to keep them running like new.

Here’s a quick example of how effective the BG244 Diesel Fuel System Cleaner really is:

2012 Dodge Ram 2500 With 6.7 Liter Cummins Diesel Engine
With only 15,000 miles on the engine, the owner of the truck wondered why he was experiencing issues with performance so early on. It turns out that even very small gum deposits within a diesel fuel system can drastically effect engine performance. With just one treatment with the BG244 Diesel Fuel System Cleaner, this truck owner experienced much faster throttle response times with “smooth as glass” idling – just like a brand new engine.

If you’ve got a diesel truck engine, and didn’t know about adding these fuel treatments, now would be the perfect time to begin properly maintaining the health of your engine. You see a lot of cars on the road with engines that are in bad shape. Don’t be a victim! Save yourself the trouble of huge mechanic repair costs with the help of these products, and you’ll be glad you did!


2. Hot Shot’s Secret P040464Z Diesel Extreme Clean and Boost – 64 fl. oz.

The Hot Shot’s Secret P040464Z Diesel Extreme Clean and Boost cleans the fuel tank, lines, and injectors, as well as removes any water from the system itself. It also lubricates the fuel pump and injectors, allowing them to run more smoothly than ever before. Cetane levels are increased through using this product, and just one 64 oz bottle treats 150 gallons of fuel.

Maintaining your diesel engine with fuel treatment additives helps to keep your engine maintenance free and safer for much longer periods than without.

Here’s a quick example from a real Hot Shot’s Diesel Extreme Clean and Boost customer so you can more clearly understand the improvement:

Fairly New 6.0L Ford F-250
Although the exact year of this truck wasn’t mentioned, at least we got the most important information. This truck owner was quoted $1,900 dollars to repair his “bad” fuel injectors. Instead of immediately handing over the cash, he went looking for less drastic (and less costly) repair options.

He decided to purchase the Hot Shot’s Secret P040464Z Diesel Extreme Clean and Boost, and the difference is like a miracle! No more cold start problems, smoother engine idling, a noticeable increase in power, and saved from having to pay $1,900 for injector replacement!

It’s shocking how foolish people can be when it comes to not knowing proper engine car maintenance. Teenagers and young adults are some of the worst offenders, simply because they don’t realize these products are out there and that they can really help!


3. Royal Purple 11755 Max-Tane Total Diesel Fuel Performance – 20 oz.

Anyone who has owned a diesel for very long knows that diesel fuel can gel during cold flow periods, that attaining higher cetane levels are important to engine performance, and that foul smoke and odor can become a problem.

Royal Purple 11755 Max-Tane Total Diesel Fuel Performance solves all the above issues, plus improves fuel economy by up to 10%, removes carbon deposits, and greatly improves overall engine performance.

Adding Royal Purple 11755 Max-Tane total Diesel Fuel Performance at every oil and fuel filter change greatly extends the life of any diesel engine. One ounce of Royal Purple per 2 gallons of fuel is recommended.

The Amazon reviews of this product speak very highly of it, with an average rating of 4.5 out of 5 stars. Customers report that using this product is a cheap and effective way to clean your injectors without having to take it to a repair shop to accomplish the same thing at a much higher cost.

According to one customer, through 10 years of using this diesel performance additive, reportedly the engines treated are still humming along nicely, which is not only indicative of the improvement claims, but also that this product doesn’t cause any damage to sensitive engine parts in the long run.

The Royal Purple 11755 Max-Tane Total Diesel Fuel Performance treatment lowers the decibel level of idling engines into a “super-quiet” state, and lowers engine sound decibels during times of high RPM load as well.
