BG 44K Fuel System Cleaner Power Enhancer

Best Fuel Injector Cleaner Reviews & Recommendations 2020

Best Overall

Chevron is well known in the automotive industry, and for good reasons. The company has a long history of producing reliable products, and Techron is no different. This fuel system cleaner is designed for a universal fuel injection treatment. It ranks as the best fuel injector cleaner additive mostly due to its patented polyetheramine technology, a formula unique to Chevron.


Knowing that gasoline is littered with impurities, this fuel injection system cleaner helps to remove carbon deposits to restore lost power and performance. Techron is most notable for working incredibly well with newer vehicles, which requires a delicate balance due to modern cars' extensive use of different materials. 


That's not to say it's less effective with older vehicles—quite the contrary. This is one of the best fuel injector cleaners for high-mileage vehicles; its aggressive recipe keeps engines clean and running smoothly. Techron is also applicable to diesel vehicles. Users should reference the abundant information Chevron provides to achieve the most significant results.


One of the very few downsides to this fuel cleaner is that it was purposely designed for repeated use which, as a result, means its effects are not long-lasting. The company suggests using a bottle every 3,000 miles or every time you change your oil.

Best Value

Lucas Fuel Treatment was chosen as our best value simply because it blows the competition away when it comes to price per ounce. This product comes in a remarkable 128-ounce container for roughly the same amount that other gasoline cleaners sell in 20 ounces. Basically, you could still buy a top-rated fuel injector cleaner for just a sixth of the cost.


This gas injector cleaner is formulated to work with both gasoline and diesel engines. Unlike other cleaning systems that use harsh chemicals to dissolve composites, the Lucas formula uses a different approach. The cleaner has a blend of slick oils and additives that essentially work as a detergent, flushing out any unwanted buildups. It also wholly neutralizes the damaging effects of low sulfur diesel fuel. This makes for a safer overall product, which means accidentally using more than the suggested amounts won’t hurt your vehicle.


While Lucas offers one of the best fuel injector cleaners, it isn't without setbacks. Despite being the cheapest per ounce, the additive only comes in large quantities. If someone is looking for a quick and cheap fuel cleaner, this would be less than ideal. Also, the large quantity could make this fuel cleaner harder to store—something to keep in mind if you have limited space.

Honorable Mention

The honorable mention for the best complete fuel system cleaner shouldn't be considered any less effective than our other choices. In fact, this fuel additive is actually the most aggressive treatment on our list. Its powerful formula and impressive results often make BG 44K a favorite among mechanics. 


For someone looking to keep their engine clean without worrying about repeated use, this system cleaner is your best answer. BG 44K produces some of the most noticeable results after one use. Drivers who notice their vehicle underperforming can simply use the product once and immediately see an improvement. 


All the power that comes with BG 44K comes at a price. The price is actually the most significant drawback; this cleaner is one of the most expensive options. In addition, if you're vehicle has proper upkeep, or you use fuel cleaners regularly, this formula is most likely too strong to be used with your car. Another shortcoming is that this product is only designed to work with gasoline-powered vehicles. So, if you own a diesel, this cannot be used with your car.

Honorable Mention

The Red Line Complete SI-1 Fuel System Cleaner removes deposits from injectors, carburetors, valves, and combustion chambers and prevents corrosion from occurring. This fuel additive features both high-temp and low-temp detergents that tackle the entire fuel system, and it promotes stability while minimizing gum and varnish build-up.


Essentially, Red Line's product lubricates the upper cylinder and both prevents and removes carbon deposits in the engine, which in turn prevents it from wearing. It's a great option if you notice that your vehicle is a little sluggish and/or pinging. While it won't dramatically improve gas mileage, it's an excellent injector and cylinder head cleaner overall.


However, it probably won't eliminate that pesky check engine light, and some users don't feel any noticeable improvement in their vehicle's performance after using it. Still, it's a popular option among car enthusiasts.

Honorable Mention

The STP Fuel Injector Cleaner is one of the most value-driven products on the market in addition to being effective. The concentrated formula's detergents reduce and remove carbon, gum, and varnish deposits on your vehicle's fuel injectors. It’s designed for vehicles that experience rough idling, hard starts, and slow acceleration.


Made with jet fuel, the STP Fuel Injector Cleaner improves vehicle performance, saves gas, and works with cap-less gas systems. It effectively cleans the cylinder heads, valves, and other parts of your fuel system. It can improve throttle response and incrementally increase gas mileage, and overall is a great value for what you get.


Some users, however, don't notice a change in their vehicle's performance after using this product. But it does what it promises and is a relatively inexpensive option.

Honorable Mention

 

Berryman Products Chemtool Carburetor, Fuel System and Injector Cleaner cleans the gas tank, intake valves, fuel pump, rings and pistons, injectors, and carburetors. Using 100-percent high-energy solvents, it removes gum, varnish, and other fuel deposits and also disperses moisture. With less than three-percent acetone, it's safe for use with catalytic converters and oxygen sensors.


The manufacturer claims that this product improves the lifespan of spark plugs and injectors, which leads to fewer repairs and less-expensive operating costs.  Users notice a district increase in responsiveness and power after adding this product to their fuel systems. Many report their engine runs noticeably better and has a smoother idle. It's also great for small engines that don't get fired up very often or run roughly.


There are few complaints about this product; however, it may be a little more expensive compared to other brands depending on where you purchase it, so make sure to shop around to get the best price.

Honorable Mention

The Sea Foam Fuel Injector Cleaner has been around since 1942 and has a reputation to live up to. This cleaner and upper cylinder lubricant restores injector spray patterns and treats up to 25 gallons. It's designed to make your engine equipment run cleaner, recover lost fuel efficiency, and minimize exhaust emissions.


It comes in an easy-to-pour bottle and is compatible with capless tanks. It's also safe to use on any gasoline fuel injection engine. After using this product, there's a good chance your vehicle will run notably smoother, and it may eliminate any pinging. It also helps if your engine is a little hesitant or runs a little roughly.


One drawback is that you may need to use more than one bottle per tank, depending on what type of vehicle you have, and that can add up in terms of cost.

Honorable Mention

The highly concentrated Royal Purple Max Atomizer Fuel Injector Cleaner is a full synthetic fuel injector cleaner designed for use with direct injection engines, although it's also compatible with other types of fuel injection engines. Its formula contains polyether amine (PEA) detergents that restore injector flow by cleaning any clogs that may be present. This, in turn, improves injector spray patterns and makes it easier for fuel to enter the combustion chamber.


After using the Max-Atomizer, you should notice better fuel economy, increased responsiveness, reduced emissions, a smoother idle, and improved starts. According to the manufacturer, it's the only cleaner that has the ability to stabilize ethanol, which can harm an engine when it breaks down. Overall, it does what it says it's going to do by boosting performance and minimizing fuel system issues.


This product is slightly more expensive than some competitor products that produce similar results, so you may want to compare it with other options before making a purchase.

Benefits of Fuel Injector Cleaner

  • Gas mileage. Cleaning out the carbon deposits in your vehicle’s fuel system helps to increase the overall gas mileage of your vehicle. This makes using fuel cleaner great for both the environment and your wallet.
  • Performance. An engine that's caked with deposits has to work harder, which means you aren't getting the best results. Keeping it clean with fuel additives can help achieve the full potential of your vehicle.
  • Lower maintenance costs. On its face, this is a controversial statement. Some people will tell you that frequent use of additives will cost you more money in the long run. However, knowing the best fuel cleaner for your situation can lower your vehicle's maintenance cost. The mileage of your car, the type of fuel you use, and how often you use these fuel cleaners are all essential factors in achieving the best results.

Some mechanics recommend using fuel cleaner before each oil change.

Types of Fuel Injector Cleaner

Dissolvents

The most common type of fuel system cleaner is a dissolvent. These products generally use polyetheramine to break down carbon composites. Over time, the impurities in the fuel start to build up in your car's injector and combustion chamber. Dissolving the build-up into smaller pieces will allow them to be ejected through the exhaust system. 

Detergents

The much less common type of fuel additive is a detergent. There is a lot of speculation over whether or not these actually help to clean out your fuel system—with most people believing that dissolving is the best option. Detergents work by activating chemicals that will force carbon deposits to slip and slide their way out of the fuel system. 

Top Brands

Chevron

Originally called the Pacific Coast Oil Company, Chevron’s history began in 1879. Since then, it has grown to become one of the largest oil businesses in the world. The highly-admired Techron is one of the best engine cleaner fuel additives available.

Red Line

Red Line Synthetic Oil began creating lubricants for the racing industry in 1979. The California-based company has since become synonymous with motorsports and producing high-quality products. It makes a top-selling fuel cleaning system with its Red Line (60103) Complete SI-1.

Royal Purple

Royal Purple is a Texas-based company well known for its oil products. Its formulators have been around for over 200 years, developing high-performance lubricants. It offers a great fuel system cleaner and stabilizer called Royal Purple Max-Clean 11722

STP

STP Oil got its start in St. Joseph, Missouri. Since 1954, the company has been producing oil treatments and additives. It rose to national fame thanks to sponsoring Nascar Legend Richard Petty in the 1970s. It offers a great fuel injector cleaner with its popular product STP 78577.

Fuel Injector Cleaner Pricing

  • Under $10: At this price point, you will find very small quantities of fuel cleaner, typically reserved for use with smaller engines like lawnmowers and dirtbikes.
  • $10-$30: This is the most common price for one bottle of the best engine cleaner additive. They are usually sold in 12- to 20-ounce containers, but the exact number varies by brand.
  • Over $30: If you see fuel cleaner over $30, it’s most likely not just a single bottle. These can be packs of multiple bottles of the same product or sets of complementary additives that one brand offers.

Key Features

PEA

Generally speaking, the most important ingredient in a fuel cleaner is polyetheramine, or PEA. This is the key component when it comes to chemically dissolving the carbon deposits. Products with this active ingredient are going to quickly and effectively clean out your system for optimal performance.

Container

Something that may help in terms of actually pouring fuel cleaner into your car is the container and size it comes in. While buying in bulk can save you money, it can be a hassle to measure out the proper amounts, which is why some containers are made to be used all at once with a full tank of gas. These smaller bottles eliminate the need for measuring cups and usually have an easy-pour spout.

Other Considerations

  • Frequency: The frequency of use depends on several factors. While it's important to consider the product's suggestion and mechanic’s advice, it mostly depends on your individual vehicle. How your car performs and reacts to fuel cleaner is very important when deciding when to use it. 
  • Driving Conditions: If you live in colder climates or often find yourself stuck in traffic, your car may be subject to more carbon buildup. These conditions are less friendly to a vehicle’s fuel system and may require you to use cleaners more often. 
  • Fuel Quality: Another disputed claim about fuel systems is whether or not using regular gas or premium gas is better. Ignoring the price factor, using regular gas is a worse option in terms of purity. So if you often use cheaper fuel, then using fuel cleaner could significantly improve your driving experience. 
  • Mileage: Overall, the manufacturing year of your car isn't a big determining factor in whether or not your fuel system will have more carbon buildup. The mileage of your vehicle, however, matters a lot. The more miles you drive without cleaning your car’s fuel system, the more time that impurities have to build up.
