Diesel Fuel All In One Additive

Product Code: ADB

Introduced in 2018 it’s become our best selling winter diesel product.

AMSOIL Diesel All-In-One (ADB) combines the superior detergency and improved lubricity of AMSOIL Diesel Injector Clean, the excellent cold-flow and anti-gelling properties of AMSOIL Diesel Cold Flow and the increased horsepower and cetane of AMSOIL Cetane Boost in one convenient package. It is safe for use in all diesel fuels, including biodiesel.

Restores Horsepower & Improves Fuel Economy

Fuel injector deposits interrupt spray patterns, causing poor fuel atomization, incomplete combustion, excessive emissions and smoke. High-pressure common-rail fuel systems are becoming commonplace as vehicle manufacturers attempt to produce more power while still meeting tightening emissions standards. In high-pressure common-rail systems, injection pressures can be 30,000 psi and higher to atomize the fuel into a fine mist for more efficient combustion, yielding increased power and fuel economy while reducing emissions. To maintain these high pressures, injector assemblies are highly engineered, with clearances as tight as 1-3 microns (a human hair is typically 70-100 microns thick). Even minimal internal diesel injector deposits on the injector pintal or other components can lead to sticking and even seizure, reducing power, fuel economy and operability. Traditional additive chemistry is not designed to address these tough-to-remove deposits.

Diesel All-In-One features advanced chemistry that delivers concentrated strength to target internal diesel injector deposits and traditional carbonaceous deposits, helping to restore horsepower and operability to like-new condition. Acceleration is improved and, with regular use, Diesel All-In-One continues to enhance performance by keeping injectors clean. The net savings on fuel can result in no additional cost of ownership.

Lubricates Fuel Pump & Injectors to Reduce Wear

Ultra-low-sulfur diesel fuel (ULSD) provides significantly reduced lubricity – a critical property in controlling wear in fuel pumps and injectors. Diesel All-In-One adds back the lubricity the fuel pump and injectors need, reducing wear, improving service life and saving time and money on maintenance costs.

Improves Fuel Quality for Peak Performance

Fuel with a higher cetane number provides for a more complete burn, resulting in improved performance. By increasing cetane, Diesel All-In-One improves the ignition quality of diesel fuel, maximizing available power and improving starting. It also smooths idle and reduces smoke and emissions.

Helps Prevent Gelling

As the temperature drops, the wax naturally found in diesel fuel begins to crystallize. The point at which wax crystals form is known as the cloud point. These wax crystals eventually clog the fuel filter and starve the engine of fuel, preventing it from starting. While low-quality fuels may form wax crystals in temperatures as warm as 40ºF (4ºC), most fuels have a cloud point near 32ºF (0ºC). The point at which the crystals clog the fuel filter is known as the cold filter-plugging point (CFPP). Diesel All-In-One lowers the CFPP by up to 40ºF (22ºC) in ULSD.

Extends Filter Life

Modern diesel engines run hot, raising the temperature of the fuel returned to the tank and causing carbonaceous deposits that collect in the fuel filter (see picture), plugging it and causing premature failure issues. AMSOIL Diesel All-In-One effectively protects against deposits, extending fuel filter life.

In warm climates it still presents an awesome value regardless of the cold flow additive. The Cetane Boost with the lubricant/Cleaner offers drivers ease of use while solving injector life issues with the needed cetane without having to separately mix in two products which require different ratios.

Lubricity Improvement

cold flow protection of diesel fuel

Fuel injectors in high-pressure common-rail diesel engines use smaller, highly engineered components to produce the higher fuel pressures needed for improved combustion. The tighter clearances invite internal diesel injector deposits that interfere with injector needle actuation, reducing performance. External deposits can also form on the injector nozzle (the typical trouble spot for traditional injectors). While many other fuel additives have yet to catch up to the internal diesel injector deposit problem, AMSOIL Diesel All-In-One targets deposits wherever they form, maximizing power, fuel economy and performance in high-pressure common-rail and traditional diesel engines.

Injector Additive Reviews:

  • Diesel Cetane Boost
    By  Jim,  a  Verified Buyer  from  Findlay Ohio  on  September 01, 2016
    I like the Cetane Boost it gives me noticeable extra power when it comes to towing. My Kubota tractor would always bog down in heavy snow and now it walks right through it. I highly recommend this product.
  • Great Product
    By  Coyote,  a  Verified Buyer  from  Alberta, Canada  on  August 30, 2016
    I am using this product in 2 older diesel engines, a 1984 Toyota Landcruiser 3B diesel with 520,000 km and a 1992 Dodge with a 5.9 ltr Cummins with 230,000 km. Mixing for a 7 point increase has given the Toyota a “seat of the pants” felt increase in power with overall fuel mileage up 1 mpg. The Dodge always had good power but with a 7 point increase mix I have gained a gear on hills and overall mileage is up 1.5 mpg. all while moving 5.5 tons of truck and load. Overall I am very satisfied with the product.
  • If you value your diesel, don’t hesitate to buy.

    Vehicle: 2008 Ford F-250 XLT 4X4; 6.4L diesel. Work and play. 105k miles. A new engine runs about $17K. I believe in ultimate lifespan (500K miles) and I use Amsoil products to achieve that goal. The Cetane Boost delivers both a smooth and more efficient power, plus improved mileage. Ford recommends No.1 diesel fuel, but that is not available where I live. Cetane Boost brings my engine to the performance level I did not receive factory new. Does it add to the cost of operation, yep, but you get what you pay for. Remember that $17K mentioned earlier? You can buy a lot of engine care for a fraction of a new engine.
