Description
AdBlue Marvell DEF 20L is a high-purity Diesel Exhaust Fluid designed for modern diesel vehicles and equipment fitted with Selective Catalytic Reduction exhaust after-treatment systems. Commonly known as DEF, AdBlue or AUS 32, this product is used in the dedicated AdBlue tank of compatible diesel vehicles to help reduce nitrogen oxide emissions from the exhaust system. It is suitable for a wide range of diesel passenger vehicles, 4WDs, utes, vans, trucks, buses, agricultural machinery, construction equipment, industrial diesel engines and fleet vehicles that specify AdBlue, DEF or AUS 32 fluid.
Marvell AdBlue DEF is made from high-purity urea and demineralised water to provide the correct 32.5% urea concentration required for SCR systems. It is not a fuel additive and must never be added to the diesel tank. Instead, it is filled into the separate DEF or AdBlue tank, where the vehicle’s SCR system meters the fluid into the exhaust stream. Under high exhaust temperatures, the DEF solution helps convert harmful nitrogen oxides into nitrogen and water vapour, supporting cleaner diesel operation and helping the vehicle maintain its emissions system performance.
This 20 litre container is a practical size for both trade and personal use. It offers more value and convenience than small emergency bottles while remaining easy to handle, store and transport. It is ideal for workshops, fleet operators, transport companies, owner-drivers, farmers, mechanics, service vehicles and diesel vehicle owners who require a reliable refill quantity without purchasing bulk IBCs or drums. The 20L pack is also suitable for keeping in a workshop, garage, depot or maintenance area so that vehicles can be topped up before dashboard warning levels become critical.
Many modern diesel vehicles fitted with SCR technology will display an AdBlue warning when the tank is low. If ignored, the vehicle may eventually reduce performance, limit restart capability or require service attention depending on the manufacturer’s system design. Keeping AdBlue Marvell DEF 20L available helps reduce downtime and provides a convenient top-up solution for vehicles that require regular DEF refilling.
AdBlue quality is important because SCR systems contain sensitive components such as DEF injectors, pumps, sensors and catalysts. Using unsuitable, contaminated or diluted product can lead to system faults, crystallisation problems, warning lights and costly repairs. Marvell AdBlue DEF is supplied ready to use and should not be diluted, mixed or modified. It must only be handled with clean equipment suitable for DEF use.

Key Features and Benefits
AdBlue Marvell DEF 20L provides a clean and reliable DEF solution for SCR-equipped diesel vehicles. Its high-purity formulation helps maintain correct SCR system operation and supports the reduction of nitrogen oxide emissions in compatible diesel engines. The product is ready to use, with no mixing or dilution required, making it suitable for regular workshop, fleet and personal vehicle maintenance.
The 20L container size offers practical handling for customers who need more than small retail bottles but do not require bulk storage. It is easy to carry, easy to store and suitable for regular top-ups across multiple diesel vehicles. For businesses operating light commercial vehicles, trucks, buses, tractors or construction equipment, this pack size is a convenient option for reducing vehicle downtime and ensuring DEF is available when required.
Using a properly formulated DEF product is important for maintaining SCR performance. Marvell AdBlue DEF helps protect the system from issues associated with poor-quality fluids, incorrect concentration, contamination or unsuitable substitutes. When stored and handled correctly, it provides dependable performance for diesel vehicles requiring AUS 32 fluid.

Handling & Storage Advice
Store AdBlue Marvell DEF 20L in its original sealed container in a cool, dry and well-ventilated area. Keep the container away from direct sunlight, heat sources, dust, dirt, fuel, lubricants, solvents, coolant, waste oil and other contaminants. DEF quality can be affected by contamination and poor storage conditions, so clean handling is essential.
Always keep the cap tightly closed when the product is not in use. Do not leave the container open for extended periods. Do not transfer DEF into containers that have previously held diesel, petrol, oil, coolant, chemicals, solvents or cleaning products. Even small amounts of contamination can affect SCR system performance and may cause faults or damage to sensitive components.
Use only clean funnels, pumps, hoses and dispensing equipment suitable for AdBlue or DEF. If DEF is spilled, rinse the area with clean water. White crystals may form if the fluid dries on a surface; these can generally be removed with water. Avoid unnecessary contact with skin and eyes and follow normal workshop hygiene practices when handling the product.
DEF may freeze at approximately -11°C. Freezing does not normally damage the product if the container remains sealed and the fluid is allowed to thaw naturally. Do not add water, anti-freeze, diesel, chemicals or any other product to prevent freezing. Do not heat the container with open flame or excessive heat.
Directions for Use
Before use, confirm that the vehicle or equipment requires AdBlue, DEF or AUS 32 fluid. Locate the dedicated AdBlue or DEF filler point, which is usually marked with a blue cap or clear label. Do not confuse the AdBlue filler with the diesel fuel tank, engine oil filler, coolant reservoir or windscreen washer bottle.
Ensure the area around the filler is clean before opening. Carefully pour AdBlue Marvell DEF into the dedicated tank using clean dispensing equipment if required. Avoid overfilling and wipe or rinse any spills with clean water. Replace the vehicle’s AdBlue cap securely after filling and reseal the container immediately if product remains.
Some vehicles may require time to recognise the refill after the engine is started. If a warning message remains after filling, refer to the vehicle owner’s manual or seek advice from a qualified technician.
Important Warnings
AdBlue Marvell DEF is not diesel fuel and must never be added to the diesel tank. Adding DEF to the fuel system can cause serious damage and may require expensive repair. Diesel, oil, coolant or any other fluid must also never be added to the DEF tank.
Do not dilute this product. Do not mix it with any other chemical, additive or fluid. Do not use the product if the container is damaged, contaminated, unsealed for a long period or suspected to contain foreign material. Keep out of reach of children and avoid contact with eyes, skin and clothing.
Suitable Customers and Industries
AdBlue Marvell DEF 20L is suitable for a wide range of customers across Australia, including diesel vehicle owners, transport companies, mechanical workshops, agricultural operators, construction businesses, commercial fleets, industrial sites, service centres and trade users. It is a practical refill option for customers who want dependable DEF supply without handling larger bulk packaging.
For passenger diesel vehicles and 4WDs, the 20L pack provides an efficient top-up size for regular maintenance. For workshops and fleets, it is a convenient product to keep in stock for vehicles that frequently return for servicing or pre-trip checks. For agricultural and construction users, it offers a portable refill solution that can be stored in service vehicles or maintenance areas where SCR-equipped equipment is operated.
