What You'll Learn
Fuel additives can improve gas mileage
However, it is important to note that the impact of fuel additives on gas mileage may be minimal and temporary. According to consumer reports and the FTC, the chances of a fuel additive significantly improving gas mileage are slim. While some products may have a slight impact, most drivers may not notice a substantial difference.
Additionally, the effectiveness of fuel additives depends on the condition of your vehicle. If your car is functioning well, fuel additives are unlikely to make a noticeable difference in performance or gas mileage. On the other hand, if your car is underperforming, a fuel additive will not suddenly transform your engine into a powerhouse of efficiency.
Furthermore, there are alternative methods to improve gas mileage that may be more effective than relying solely on fuel additives. For example, ensuring proper maintenance of your vehicle, such as keeping your tires inflated, driving gently, and using fuel-saving techniques, can contribute to better gas mileage.
It is worth noting that fuel additives can help address specific issues with your vehicle. For instance, PEA-based fuel injector cleaners have been proven to restore severely neglected engines to almost factory-specified fuel mileage. Fuel additives can also help remove soft deposits and varnish build-up in filters, improving engine performance.
In conclusion, while fuel additives may offer some benefits in certain scenarios, they should not be relied upon as a standalone solution for improving gas mileage. Combining their use with proper vehicle maintenance and fuel-saving techniques will likely yield more noticeable and lasting results.

Fuel cleaners can help remove varnish deposits
Fuel injectors and fuel system cleaners are effective in cleaning up varnish deposits that may build up in a filter. Varnish is a common contaminant that can be easily dissolved, and injector performance can be restored quickly.
For example, Sea Foam liquefies varnish and cleans fuel tanks in motorcycles. It is recommended to remove as much old fuel as possible, as varnish sits at the bottom of the tank. Then, add a can of Sea Foam to the remaining fuel, followed by a gallon of fresh fuel. Run the engine for 8 minutes to allow the Sea Foam to pass through the carburetor circuits. After letting the motorcycle sit for a few days, add another gallon of fresh gas and run the engine for 5 to 8 minutes.
In another instance, a user on an online forum recommended using Sea Foam to clean fuel varnish from a boat's built-in tanks. They suggested recirculating gas and Sea Foam for about 45 minutes to clean the tank.
It is worth noting that fuel system cleaners may not dissolve all types of dirt and contaminants. Solid contaminants like rust, silt, debris, and sand are challenging to dissolve with fuel cleaners. Therefore, it is recommended to run fuel cleaners before changing the filter to capture any loosened contaminants.
Additionally, some sources suggest changing the fuel filter before adding fuel system cleaners to avoid burning the newly dissolved contaminants in the engine. Overall, fuel cleaners can effectively remove varnish deposits, but they may not be suitable for all types of contaminants, and proper procedures should be followed for optimal results.

Additives can reduce emissions and neutralize gasoline effects
The use of fuel additives is a cost-effective and straightforward method to improve combustion and reduce the harmful emissions of internal combustion engines. They can also improve fuel properties, leading to higher efficiency. For example, Poulopoulos and Philippopoulos (2000) found that blending MTBE in gasoline reduced CO and HC emissions at high loads. Similarly, diethylamine, when blended with baseline gasoline, was found to reduce carbon emissions.
Detergents are the most common additives used in gasoline. They help to clean and prevent deposits on fuel injectors and intake valves, improving engine performance and longevity. Some examples of detergents include polybutene amine (PBA), polyisobutylene amine (PIBA), and polyether amine (PEA). PEA is considered the most effective and is used in many premium gasoline products.
Volatility modifiers, such as butane, are another type of additive that helps control gasoline's volatility. They ensure easy engine starting, warm-up, and the prevention of vapor lock. However, excessive volatility can increase evaporative emissions, so a careful balance is necessary.
Fuel additives can also prevent and clean carbon deposits from inside engines, which is crucial with the widespread use of gasoline direct injection. Additionally, some additives can improve lubricity and fuel performance, quality, and safety.
Regarding fuel filters, fuel system cleaners can dissolve some contaminants in the fuel filter, allowing them to pass through the fuel system and be burned in the engine. This suggests that it may be advisable to change the fuel filter before adding fuel system cleaners to avoid burning the contaminants in the engine. However, it is important to note that fuel system cleaners are primarily designed to remove soft deposits, varnish, and similar build-ups, rather than solid contaminants.

Cleaners should be used after changing the filter
Using a fuel system cleaner after changing the filter is generally recommended, especially if you have a high-mileage vehicle. Here's why:
First, it's important to understand that fuel system cleaners are designed to remove varnish, carbon build-up, and other soft deposits from fuel injectors and the fuel system. They are effective at dissolving these contaminants, which can then be burned in the engine without causing harm. However, when it comes to solid contaminants like rust, silt, debris, or sand, fuel cleaners are less likely to dissolve them, and they will remain lodged in the fuel filter.
Now, if you were to use a fuel system cleaner before changing the filter, it could dislodge sludge and debris from the gas tank, which would then be captured by the new filter. This can shorten the lifespan of the new filter as it becomes loaded with contaminants. Therefore, it is often advised to use a fuel system cleaner after changing the filter to prevent this from happening.
Additionally, some sources suggest that fuel system cleaners can be beneficial after changing the filter as they can help remove any loosened contaminants that may have accumulated in the old filter. By using the cleaner afterward, you ensure that these contaminants are flushed out of the system and don't end up back in the new filter.
Finally, it's worth noting that some fuel additives or cleaners, such as injector cleaners, can be added directly to the new fuel filter as a form of preventative maintenance. This practice is recommended by some car manufacturers and can help maintain the health of your fuel system. However, it is generally advised to consult your car's manual or a trusted mechanic for specific recommendations regarding the use of fuel additives and their frequency.

Fuel additives can improve engine performance
Fuel additives are unique substances added to gasoline, diesel, and other types of fuels to enhance their performance, reduce engine wear, improve fuel efficiency, and minimize pollution. They are particularly beneficial for diesel engines, where they can improve combustion efficiency and reduce the amount of soot and other pollutants released into the atmosphere.
There are two primary types of fuel additives: fuel performance enhancers and fuel stabilizers. Fuel additives for performance are intended to improve the capabilities of your vehicle. For example, biocides are fuel additives that kill bacteria and other microorganisms, such as bugs, algae, yeast, and fungi, that can grow in diesel fuel, clog filters, and damage fuel systems. Fuel stabilizers, on the other hand, are used to maintain fuel quality during long-term storage by preventing the breakdown of fuel, which can result in the formation of gums, varnishes, and other deposits.
Fuel additives can also clean out harmful deposits, reduce wear and tear, improve fuel efficiency, prevent fuel breakdown, and help engines last longer. For instance, fuel system cleaners scrub carbon and other buildup from your fuel system, helping your car's overall performance. Octane boosters improve the combustion quality of gasoline, increasing fuel's resistance to 'knocking' or spontaneous combustion, which can lead to engine damage.
However, it is important to note that if you are using high-quality fuel, there is generally no reason to use any additives as "preventative maintenance". If an additive does fix your problems, it will only be temporary, and you should instead find out why your fuel system isn't staying clean. Additionally, it is recommended to consult a trusted mechanic and follow the maintenance calendar in your owner's manual before using any fuel additives.
