What You'll Learn
Chevron Techron is Toyota-approved and recommended by customers
Toyota recommends Top Tier gasoline in the owner's manual, which uses a higher level of detergent additives compared to other retailers that use only the minimum EPA-required detergent additives. The detergent additives reduce the buildup of harmful engine deposits, which may reduce fuel economy and optimal engine performance. However, Chevron Techron is also Toyota-approved and recommended by customers.
Techron® Complete Fuel System Cleaner is designed for gasoline engines and can be used in vehicles with less than 75,000 miles. It provides the same performance benefits as Techron® High Mileage Fuel System Cleaner. Normal, everyday engine combustion can cause carbon deposits to build up throughout the fuel system, which can clog the fuel injectors and impede the flow of fuel. Techron® is formulated to work in both older and newer engines, cleaning clogged fuel injectors, dirty carburetors, intake valves, and combustion chambers.
Toyota owners have reported positive experiences with Techron, with some noting that it cleared a CEL for lean misfire and improved their car's performance. One user reported that their 1997 Camry with 117,000 miles picked up an extra 2 MPG on a highway trip after using Techron. Another user with a 10-year-old Prius reported no issues with their car, which has close to 97,000 miles, and only uses Techron about once a year.
It is important to note that while Techron is a recognised and effective product, it is not a cure-all. It is primarily for preventative maintenance and will not repair damaged injectors. Additionally, while it is safe for gasoline engines, it should not be used in diesel engines as it will raise the sulfur content, making it difficult to pass clean air emission standards.

BG44K is expensive but one user says it's worth it
Although BG44K is expensive, some users say it's worth it. BG44K Fuel System Cleaner is a product that can be added to gasoline to quickly and effectively clean the entire fuel system, including fuel injectors, intake valves, ports, and combustion chambers. It is designed to remove upper engine deposits, reducing issues such as engine surge, stalling, hesitation, and power loss.
BG44K has received positive reviews from customers, with some reporting that it saved their car from needing fuel injector replacement and improved their vehicle's performance. One customer mentioned that using BG44K made their 2008 Yamaha FJR1300 run like new, with no more popping and acceleration lag. Another customer observed that it helped rejuvenate their car, taking it from knocking and stumbling to running smoothly.
However, it's important to note that customer experiences with BG44K vary. While some customers reported positive results, others mentioned that their check engine light came on after a few days of using the product.
BG44K is designed to keep the fuel system clean and deposit-free. It is compatible with all fuel system materials, alcohol-blended fuels, and common fuel additives. It does not contain any alcohol and is safe for catalytic converters and oxygen sensors.
Toyota recommends using a fuel injector cleaner once every two years or 40,000 km to maintain optimal performance. This can help restore engine performance and improve fuel economy while reducing emissions.

Seafoam is another product that some Toyota owners use
While some Toyota owners swear by Seafoam, others believe there are much better products on the market. For example, one user on the Toyota Nation Forum states that Seafoam doesn't contain either of the two most effective fuel injector and fuel system cleaners: polyisobutylamine (PIBA) and polyetheramine (PEA). They also question the effectiveness of the Pale Oil in cleaning fuel injectors.
Another user on the same forum calls Seafoam a "rip-off," suggesting that it is a waste of money and that there are more effective products available that are based on scientific evidence. However, they acknowledge that many consumers claim that Seafoam has worked wonders for them.
Seafoam typically costs around $12 a pint, and some Toyota owners use it religiously on all of their cars via the oil and fuel tanks. They claim that there are plenty of videos on YouTube proving that it works.

Polyether Amine (PEA) detergent-containing products are good
Polyether Amine (PEA) is a nitrogen-based detergent that is stable enough to withstand the harsh conditions of a combustion chamber. It is the most potent detergent available for cleaning carbon deposits in fuel systems and is the only cleaning agent proven to clean the combustion chamber, piston tops, and cylinder heads. PEA also cleans ports, valves, and GDI and port injectors, and keeps them clean for up to 3,000 miles. Its molecules have a nitrogen head that attaches to the carbon deposit and lifts it away, while the fuel-soluble tail of the molecule pulls the deposit off the surface to be burned or flushed out through the exhaust.
The detergent additives in PEA-containing products can effectively reduce the accumulation of coke deposits in engines and improve exhaust emission pollution. The cleaning effect of these detergent additives depends on their contents and compositions. Typically, they contain a terminal amino group linked to oligomers. The carrier oils are also oligomers, such as polyether, which are very similar to the main chains of the active components.
The formation of vesicles is vital for the ninhydrin reaction of polyetheramines. The detergent additives added to gasoline can improve exhaust emission pollution and reduce the accumulation of coke deposits in the engine. Unlike small molecule compounds containing amino groups, such as amino acids and alkylamines, the formation of vesicles significantly increases the reactivity between polyetheramines and ninhydrin.
When diluted in the fuel tank, a petroleum distillate's deposit-removing abilities are minor to non-existent. However, in certain products, the distillate is a carrier fluid that increases the effectiveness of PEA by helping it mix easily into the fuel. Petroleum distillate is an effective solvent and removes sludge when added to the fuel system as a concentrate. It also helps deliver the full concentration of actives to where they are needed.
Some users have reported positive experiences with PEA-containing products. One user reported that Chevron Techron cleared a CEL for lean misfire in their granddaughter's Echo, and the issue did not recur for the next 20,000 miles. Another user recommended Gunk Fuel Injector & Carburetor Cleaner, which contains Polyetheramine as the cleaning agent, and BG44K, which they found effective in restoring old injectors.

Toyota recommends its own injector cleaner at every maintenance service
It is recommended to use injector cleaning products that are specifically designed for Toyota vehicles. Toyota's own injector cleaner is a good option, and it can be purchased from a Toyota Service Centre or an authorized dealer. This product is designed to remove carbon deposits from various engine components, such as injection nozzles, intake valves, spark plugs, and combustion chambers. Using it can help restore engine power, improve throttle response, and ensure smoother engine startups.
Toyota recommends using its injector cleaner at every periodic maintenance service to maintain optimal engine performance. This is typically suggested once every two years or 40,000 kilometers, but it can also be used more frequently if needed to address specific performance issues. The frequency may vary depending on the model and type of Toyota vehicle, so it is always a good idea to refer to the Service & Warranty logbook for specific recommendations for your particular Toyota model.
While there are other injector cleaner products on the market, such as Chevron Techron, Redline SI-1, and Gumout Regane, the Toyota Genuine Injector Cleaner is specifically formulated for Toyota vehicles and can provide the best results in terms of performance and maintenance. It is designed to work effectively with both petrol and diesel engines in Toyota cars.
Using a fuel injector cleaner can help address issues caused by deposits that build up over time. These deposits can lead to reduced engine power, poor fuel economy, and increased emissions. By using a cleaner, these deposits can be dissolved into the fuel and burned during the combustion process, restoring the engine to its optimal performance and improving the overall driving experience.
In addition to using a fuel injector cleaner, it is also important to use high-quality fuel and to maintain regular engine maintenance, including oil changes and other recommended services. This comprehensive approach will help ensure that your Toyota vehicle performs at its best and provides a reliable driving experience for years to come.
