Fuel injector cleaners may not be necessary, as modern gasoline has additives to keep injectors clean
Fuel injector cleaners are liquids that are added to the fuel tank to clean injectors and cylinders. However, fuel injector cleaners may not be necessary, as modern gasoline already contains additives to keep injectors clean. One source states that "the gasoline in the pumps in the US has had more than enough cleaner additives to keep the injectors clean for probably 15-20 years now". Another source states that "clogged fuel injectors are pretty much a thing of the past except in very rare circumstances".
Despite this, fuel injector cleaners are still widely available and some people continue to use them. There are several reasons why someone might choose to use a fuel injector cleaner. One reason is that they believe it will improve the performance of their car. In some cases, fuel injector cleaners may be able to remove carbon deposits or varnish from the fuel rail, which could potentially improve performance. Additionally, some people may choose to use a fuel injector cleaner if they are experiencing issues with their fuel injectors, such as clogging or varnish build-up.
However, there are also potential drawbacks to using fuel injector cleaners. One concern is that they may cause the spark plugs to run too hot, particularly in aluminium engines. This is because some fuel injector cleaners are alcohol-based, and alcohol can affect engine temperature. Another potential issue is that fuel injector cleaners may not be effective at cleaning the cylinders, even if they do clean the fuel injectors. Additionally, some people may be concerned about the cost of fuel injector cleaners, as they can be expensive.
Overall, while fuel injector cleaners may be beneficial in some cases, they may not be necessary for most people due to the presence of additives in modern gasoline. It is important to weigh the potential benefits against the potential drawbacks before deciding whether or not to use a fuel injector cleaner.

Water can be used to clean spark plugs
While it is technically possible to clean spark plugs, it is not recommended as they will not perform as well as new spark plugs. To clean them, you would need to use a fuel injector or brake cleaner, and this can cause the spark plugs to overheat.
Water cannot be used to clean spark plugs. To clean spark plugs, you need to use a wire brush to scrub the threads of the spark plug, removing built-up oil and grime. You can also use sandpaper on the electrode to remove any discolouration. This process requires the spark plugs to be removed, and the area cleaned with compressed air to prevent debris from falling into the cylinders.
Some fuel injector cleaners are alcohol-based, and this can cause the engine to overheat. This is because alcohol has a cooling effect, but only when running 100% alcohol, like methanol. Modern engines with oxygen sensors will overcompensate when alcohol is in the gas, reducing gas mileage.
While it is possible to clean spark plugs with a fuel injector, it is not recommended due to the potential for overheating. It is also important to note that cleaning spark plugs may contribute to the wearing of the edges, reducing their performance. Therefore, it is generally recommended to replace spark plugs rather than attempt to clean them.

Fuel injector cleaners may not improve performance
Fuel injector cleaners are designed to remove deposits and carbon buildup from fuel injectors and other parts of the fuel line. This buildup can cause a noticeable loss of engine power and an increase in fuel consumption, so cleaning fuel injectors can help maintain their performance and prevent further damage.
However, fuel injector cleaners may not always improve performance, especially in older vehicles with extremely grimy engines. Here are some reasons why:
Engine Condition
The improvement rate of a fuel injector cleaner depends on the condition of the engine. If you are using a high-strength cleaner on a newer engine with minimal buildup, you may see rapid improvements in performance. However, if your vehicle has an older engine with increased contamination in the fuel system, it may take longer for the cleaner to have a positive effect, and performance improvements may be less noticeable. In some cases, a very old vehicle that hasn't been maintained properly may be beyond the help of even the best cleaner.
Type of Cleaner
The type and quality of the fuel injector cleaner used also play a role in its effectiveness. Most cleaners contain chemicals like polybutene amine (PBA) that are formulated to break down deposit buildup. However, not all cleaners are created equal, and some may be more effective than others depending on the specific needs of your engine. It is important to choose a high-quality cleaner that is suitable for your vehicle's make, model, and fuel type.
Regular Maintenance
Fuel injector cleaners are most effective when used as part of regular maintenance. Most manufacturers recommend cleaning fuel injectors every 15,000 to 30,000 miles, or at each oil change, to prevent buildup and keep the engine running smoothly. However, if you wait too long between cleanings or neglect other aspects of engine maintenance, performance issues may become more difficult to reverse.
Mechanical Issues
While fuel injector cleaners can help maintain fuel injector performance, they are not a cure-all for all engine problems. If your vehicle is experiencing issues such as a malfunctioning fuel injector, blocked fuel lines, or mechanical component damage, a fuel injector cleaner alone may not be sufficient to improve performance. In these cases, it is recommended to consult a specialist or a reliable repair shop to accurately diagnose and address the issue.
