FAQs

Australia's diverse marine environments, from tropical north to temperate south demand consistent fuel quality for safe and efficient boating. Poor-quality diesel often contains water, microbial growth, and sediment, which can clog filters, damage injectors, and compromise combustion. These issues not only increase maintenance costs but also raise the risk of engine failure at sea - a scenario no boat owner wants to face.

The demulsified in Amplify Diesel helps to separate any water present in the fuel so that it does not enter the engine. This can assist in reducing the potential growth in bacteria in the fuel as the water layer will generally sit below the fuel and not in contact with any air present in the top of the fuel tank.

Long term mooring presents unique fuel challenges. When boats remain idle for months, diesel can degrade and become a breeding ground for bacteria and fungi. These microorganisms feed the hydrocarbons, creating sludge and acids that corrode fuel systems. Seasonal temperature changes also cause condensation inside tanks, introducing water that accelerates microbial growth.

Without proactive fuel management, boats left moored for extended periods often face severe engine problems when they return to service. Amplify Diesel is compatible with the existing additive products available at the Royal Motor Yacht Club Broken Bay should owners wish to treat their fuel tanks and provide additional assurance against the potential for microbial growth when in long term storage.

Ampol Amplify Premium Diesel has been developed and tested to suit the typically tough Australian conditions that engines need to perform under. We continually improve our extensive range of fuels to ensure we keep pace with engine technology developments. Amplify Premium Diesel fuel has the latest deposit control additive technology with proven performance tested against industry standards and local trials. The worldwide Fuel Charter (WWFC) for quality can significantly affect engine and vehicle operation, durability and emissions performance. Its sixth edition published in 2019, states that the conformity of modern engines with their specified performance in terms of power, fuel consumption and emissions over time will depend largely on the cleanliness of their injectors

Unlike regular fuels, our Amplify Premium Fuels contain an advanced multi-function additive to remove carbon deposits from the tips and the inside of the injectors. These carbon deposits disrupt the flow of fuel into the engine and this can result in hesitation under acceleration, rough engine running and increased fuel use. The detergent additive cleans the fuel system for optimum fuel flow and the corrosion inhibitor protects metallic surfaces and prevents the formation of abrasive rust particles that can cause damage to injectors.

The Foam inhibitor in Amplify Diesel prevents the formation of foam during refueling that can lead to spills resulting in a cleaner, faster fill

Amplify Diesel is fully compatible with regular un-additised fuel without any harm or short-term adverse performance to the engine.

However, Amplify Diesel is designed to remove the carbon deposits that form on the tips and inside the surfaces of the fuel injectors and intake valves. As the surfaces are cleaned, the protective additive components in Amplify Diesel coat the surfaces to prevent the buildup of carbon deposits.

The ongoing use of Amplify Diesel keeps this protective layer intact and prevents the formation of carbon deposits. When switching to regular, un-additised diesel, the protective layer gradually washed away leaving the unprotected surface susceptible to carbon deposit formation.

Ampol has developed unique, fuel additive technology that is injected into Amplify Diesel when the fuel tanker is being loaded at the terminal. This injection process is called additising and additised denotes any fuel that contains fuel additives.

Amplify Premium Diesel contains an advanced multi-function additive that includes a cleaning agent, a demulsifier, and rust inhibitor which clean and protect your engine. It also has an anti-foaming agent which reduces the incidence of foaming during refueling for a cleaner and faster fill experience. The multi-function additive is not present in regular diesel, only Amplify Premium Diesel hence why we differentiate this product as premium.

The cleaning agent in Amplify Diesel starts working immediately but the resultant benefit will be dependent upon the level of injector fouling. Continuous use of Amplify Premium Diesel will result in the clean-up of fuel injectors deposits, keep clean of fuel system components and the potential recovery of loss power and fuel efficiency. The time this will take will vary according to vehicle condition, drive behaviour and trip characteristics.

Most modern combustion engines employ high pressure direct fuel injection systems for optimum control of the fuel flow. This type of system places the injector inside the combustion chamber where it is directly exposed to the temperature and pressure of combustion. Deposits form when small amounts of fuel remain on the injector tip surface after the engine is stopped. The residual heat in the injector effectively cooks the fuel leading to a carbon-based deposit forming on the injector surface.

A second source of deposits originates from micro-contaminants in the fuel itself. The modern supply chain of fuel is complex and involves refining, sea freight, pipelines, tanker trucks and retail dispensing. Microcontaminants form due the additives that may be introduced during the refining process, salt contamination during shipping and insufficient filtration in the vehicle itself.

Both these sources of deposits can lead to blocked nozzles in the injector tip and binding of the internal injector mechanism which can affect the flow of fuel into the combustion chamber. At best, the fuel flow may be restricted and potential uneven spray pattern which leads to a loss of power. At worst, the injector may work intermittently or will severely restrict the flow of fuel which can lead to a significant loss of power.
