Choosing the right fuel injector cleaner for your car can add more years to your motor, improve gas consumption, and reduce harmful emissions.
But choosing between the hundreds of different fuel injector cleaners on the market can be a daunting task. In this article, we’re going to review 10 of the best fuel injector cleaners so you can make a sound decision.
Best Fuel Injector Cleaners of 2020
1. Red Line (60103) Complete SI-1 Fuel System Cleaner
Red Line Complete SI-1 Fuel system cleaner is one of the most well known and reputable brands of injector cleaners out there. It combines a variety of detergents that work at both high and low temperatures.
The Red Line Complete SI-1 Fuel system cleaner removes 100% of the carbon deposits on valves, carburetor, fuel injection system, and the combustion chamber.
One of the reasons we rated this brand number one is because of how concentrated it is. This fuel injector cleaner contains more PEA’s per oz than any other injector cleaner in its category. It is also one of the most efficient. Only one-third of the recommended dosage is enough to notice a significant difference in gas combustion.
All in all, the Red Line Complete SI-1 fuel system cleaner offers the most bang for your buck than any other cleaner on the market and was able to keep injection systems clean well after it’s utilization.
2. Chevron 65740 Techron Concentrate Plus Fuel System Cleaner
Chevron is one of the most well known automotive service companies and is known for the quality of their products and the Techron concentrate fuel system cleaner is no exception. It features a patented PEA technology that cleans injection systems as well as the combustion chamber and other components with ease.
It also cleans intake valves as well as ports and works on a wide variety of engines.
The only downside to this product is that it doesn’t work with diesel or two-stroke air-cooled engines. So, unless your car is equipped with one of these two engine types, the Techron is a nearly perfect product.
3. BG 44K Fuel System Cleaner
The BG 44k fuel system cleaner is a complete cleaning solution for fuel injectors, combustion chambers, and the entire fuel system. It incorporates a wide variety of cleaning agents in one complete highly concentrated solution that thoroughly cleans the whole fuel system.
One of the greatest benefits of this fuel injector cleaner is how concentrated it is. Only half of the container is enough to clean a 2.0 liter motor with a 10 gallon tank. As a matter of fact, it is so concentrated that it is recommended that you wait until your engine is completely gunked up before using it.
The only downside with this product is that it works with gas-only and that it only treats components related to the fuel system, so if your engine problems are caused by other components, this fuel injector system won’t be of much use.
4. 3 Pack Bg 44k Bg44k Fuel System Cleaner Power Enhancer
The 3 Pack Bg 44k Bg44k Fuel System Cleaner Power Enhancer 11 Oz Cans is a complete cleaning solution that was created not only to clean the whole fuel system but also contains additives that improve performance. It thoroughly removes deposits from intake valves, ports, combustion chambers, and intake manifolds as well as fuel filters with ease.
What’s great about this fuel injector cleaner is that it works on most fuel systems and fixes motor problems caused by buildups such as engine surge, power loss, or hesitation. This fuel injector system improved gas consumption on most models almost immediately. There really isn’t much bad we can say about this product except for the fact it is not the most affordable on the market.
However, the improvement in gas consumption and performance largely makes up for this fact. This is why we ranked this product number 4 on this list.
5. 3M 08812 Injector Cleaner Bottle
The 3M 08812 Injector Cleaner Bottle is a complete all in one solution that was formulated for a wide variety of vehicles. It does a great job at removing carbon deposits and revigorates the engine by cleaning the intake valves as well the injectors to improve throttle response, economy, and performance.
It is also extremely easy to use and affordable. All you have to do is pour the whole content of the bottle and wait until your gas tank is emptied for all the benefits to take effect. Only one bottle per 3000 miles is recommended. The only issue with this injector cleaner is that it’s not as concentrated as others in the same category, so this product might not work as well on heavily clogged injection systems.
But other than that, this product was nearly perfect, and this is why we ranked it at number 5.
6. Sea Foam SF-16 Motor Treatment
The Sea Foam SF-16 Motor Treatment is a complete cleaning solution that works for gasoline engines as well as diesel. It is an EPA certified product, meaning that it is completely safe for the environment. This treatment liquefies deposits in the whole fuel system, from carburetors and fuel injectors all the way up to sticky valve lifters.
Most users have noted an almost immediate boost in performance right after using this product. And what is great about this product is that it also cleans up oil as well, which allows this treatment to access components a regular fuel injector cleaner can’t. The only issue people had with this product is that it didn’t seem to work as well on antique models.
A lot of people also complained about the price. But besides these few minor issues, most customers were satisfied with this product, and this is why we ranked this product at number 6 on our list.
7. Royal Purple 11722 Max-Clean Fuel System Cleaner and Stabilizer
The Royal Purple 11722 is a 3 and 1 solution that works not only as a fuel injector cleaner but as a fuel stabilizer as well. This product works wonders on Diesel as well as gasoline engines and can improve horsepower on your vehicle up to 5%.

It is also perfectly safe for 4 cycles or 2 cycle engines. The only issue with this product is that many people reported no change whatsoever when it came to minor issues, but that was probably due to the fact that the problems weren’t directly related to the fuel injection system.
But this product still managed to make it to number 7 on our list due to its impressive effect on horsepower as well as its versatility and convenience.
8. ACDelco X66P Fuel Injector and Upper Engine Cleaner
When it comes to car products and equipment, few names are as recognizable as ACDelco. And this because of their long standing reputation for quality, and the ACDelco X66P Fuel Injector and Upper Engine Cleaner is no exception.
This cleaner works on in rail fuel injectors, combustion chambers, and other hard to reach areas such as stuck piston rings. This product claims to improve cylinder compression by 50%, and users have reported an almost immediate improvement in performance and fuel consumption right after we used the product.
They also reported improvement with problems such as hard starting and stalling. However, the biggest issue with this product is that it has to be poured in by a professional who will feed it trough a dripper while the engine is running. But besides this, there wasn’t much bad we could say about the ACDelco X66P, and this is why it is at number 8 on our list.
9. Chevron 65740-CASE Techron Concentrate Plus Fuel System Cleaner

While most users were satisfied with this product, some claimed that they only had a slight improvement in miles per gallon. In addition, this fuel system cleaner is one of the most expensive on the market and does the same job as some of its other less expensive competitors.
This is why we had to put the Chevron 65740-CASE Techron Concentrate Plus Fuel System Cleaner – 20 oz. at number 9 on our list.
10. Lucas 10003 Upper Cylinder Lubrication & Injector Cleaner
The Lucas 10003 Upper Cylinder Lubrication & Injector Cleaner 32 oz. advertises itself as a “tune-up in a bottle”, and it definitely delivers on its promise.

In addition, the Lucas 10003 upper cylinder and injector cleaner contain absolutely no solvents that could otherwise harm engine components. The solution is extremely easy to use and works on both Diesel and gasoline engines.
Even if this product works great on a wide variety of vehicles, it is not recommended for use on motorcycles with pre-jetted carburetors since unclogged deposits run the risk of accumulating in the carburetor. Results also seemed to be irregular between car models. Besides these factors, the Lucas 10003 still comes highly recommended and is at number 10 on our list.
Choosing the right fuel injector can add years to your vehicle and greatly reduce gas emissions, fuel consumption, and maintenance costs. So if you care about your vehicle and want to reduce the amount of costly visits to the mechanic, we suggest that you choose the best fuel injector cleaner for your vehicle.
