Fuel additives can improve combustion, fuel efficiency, and engine cleanliness
Fuel additives are compounds added to a fuel tank to improve combustion, fuel efficiency, and engine cleanliness. They are available from auto retailers and dealers, and some car manufacturers, such as Audi, also offer their own fuel additives.
There are several types of fuel additives, each with its own benefits. For example, cetane boosters improve combustion and power by increasing the diesel fuel's ignition quality. This can be particularly useful for starting a diesel engine in cold weather and reducing emissions. Fuel stabilisers, on the other hand, prevent fuel degradation and protect engine components from rust, thus extending fuel longevity. Octane boosters are another type of additive that enhances a vehicle's fuel octane rating, allowing the fuel to withstand higher pressures and temperatures, which can lead to improved engine efficiency.
Lubricity improvers are additives that generate a protective layer on fuel system components, reducing friction and preventing premature wear and tear. This not only saves the engine from corrosion but can also provide significant financial savings. Anti-gel additives are another type of additive that helps improve engine efficiency in cold weather by lowering the fuel's gelling point.
Some drivers opt for fuel additives to improve their vehicle's performance and protect their engines. For instance, one Audi Q5 driver adds a DPF filter cleaner liquid every two tanks to prevent DPF problems. Another driver, with a Mercedes diesel, used a Liqui Moly Super Diesel Additive to eliminate a hpfp squeal.
While fuel additives can offer benefits, it is important to use them with caution. For example, excessive use of lubricity boosters can cause reactions with fuel contaminants, leading to clogged filters. Similarly, overuse of cetane boosters can result in deposits forming in fuel injectors and combustion chambers, potentially causing issues.

Anti-gel additives can improve engine efficiency in cold weather
Diesel fuel has many advantages, including greater vehicular power and fuel economy. However, it performs poorly in cold weather. When temperatures drop, diesel forms crystals that clog fuel filters and lines, causing engines to fail to start and even leading to costly repairs. To prevent this, anti-gel additives are used.
Anti-gel additives improve engine efficiency in cold weather by lowering the freezing point of diesel fuel, reducing the likelihood of freezing. They are designed to lower the Cold Filter Plugging Point (CFPP), which is the lowest temperature at which fuel will flow through a specific filter. By lowering the CFPP, anti-gel additives ensure that fuel can still flow through the filter even at lower temperatures.
The wax crystals that form in diesel fuel at low temperatures can clog fuel lines and cause issues for diesel engines. Anti-gel additives improve cold-temperature performance by lowering the cloud point of the fuel, increasing the lubricity of the wax molecules, and preventing them from sticking together and clogging lines and filters.
Some popular anti-gel additives include Hot Shot's Secret Diesel Winter Anti-Gel and Lucas Oil Anti-Gel. Hot Shot's Secret Diesel Winter Anti-Gel uses three different chemicals: a wax modifier, a wax anti-settling agent, and a military-grade de-icer. It improves winter operability and fuel economy while preventing gelling and icing. Lucas Oil Anti-Gel is added to ultra-low sulfur diesel fuel to prevent fuel thickening and gelling in cold temperatures.
In addition to anti-gel additives, some other fuel additives can improve engine efficiency. For example, Fuel Ox® Infinity Lube™ SG, Liquid Friction Eliminator, and Super Spray have been found to increase mileage, improve diesel performance, and result in a quieter engine operation. Liqui Moly Diesel fuel additive has also been reported to improve fuel quality, raise Cetane, and add lubricity.

Cetane boosters improve how well diesel fuel burns by raising its cetane number, which directly affects how smoothly an engine runs. They can be particularly useful for starting a diesel engine in cold weather, and they can also help with rough starts and excessive engine noise.
Fuel stabilisers, on the other hand, aim to stop the degradation of fuel. They protect engine components from rust and can extend fuel longevity. This is especially useful for diesel fuel that is stored for long periods, as it can be prone to oxidation and the growth of microbes.
Octane boosters are liquid additives that enhance a vehicle's fuel octane rating, allowing the fuel to withstand higher pressures and temperatures, and potentially enhancing engine efficiency.
Other types of fuel additives include lubricity additives, which improve the lubrication of moving parts, reducing wear and prolonging the engine's life. Cold flow improvers are another type of additive that is essential for diesel fuels in colder climates, as they prevent the fuel from gelling and clogging fuel lines and filters.
While some Audi diesel fuel users have reported using fuel additives with positive results, others have noted that they are not worth the money and can cause issues in older engines. It is important to carefully consider the use of fuel additives and consult with experts to determine the specific needs of your vehicle.
