The automotive diesel exhaust fluid market size has grown strongly in recent years. It will grow from $29.14 billion in 2024 to $32.01 billion in 2025 at a compound annual growth rate (CAGR) of 9.9%. The growth in the historic period can be attributed to increased awareness of environmental issues, increased regulatory compliance, increased vehicle miles traveled, DEF distribution network establishment, and increased public awareness.

The automotive diesel exhaust fluid market size is expected to see strong growth in the next few years. It will grow to $46.21 billion in 2029 at a compound annual growth rate (CAGR) of 9.6%. The growth in the forecast period can be attributed to global harmonization of regulations, expanding average age of vehicles and miles, expansion of distribution networks, fleet management practices, and ongoing investment in DEF refueling stations. Major trends in the forecast period include technological developments, integration with IoT, improved storage and handling, enhanced user interfaces, advanced DEF quality testing, and improved DEF handling and storage solutions.

The increasing number of diesel-powered vehicles is anticipated to drive the growth of the automotive diesel exhaust fluid (DEF) market in the coming years. Diesel-powered vehicles use engines where fuel ignites due to the high temperature generated by air compression within the engine's cylinders. The rise in diesel-powered vehicles is attributed to their higher fuel efficiency, robust torque output, and advancements in emissions technologies, making them especially beneficial for commercial, industrial, and heavy-duty uses. Automotive DEF plays a key role in helping these vehicles reduce harmful NOx emissions, ensuring compliance with environmental standards while maintaining engine performance. For example, a report from the Bureau of Infrastructure and Transport Research Economics, an Australian professional non-governmental organization, revealed that as of January 31, 2023, there were approximately 6 million diesel-powered vehicles registered in Australia, a 5.3% increase from the previous year. As a result, the rising number of diesel-powered vehicles is boosting the automotive DEF market.

Leading companies in the automotive diesel exhaust fluid market are expanding their DEF product offerings, including anti-crystal additive concentrates, to enhance vehicle efficiency and meet stricter emissions standards. An anti-crystal additive concentrate is a specialized additive in diesel exhaust fluid (DEF) that prevents the formation of crystals, which can clog or damage the exhaust system. For instance, in March 2024, Liqui Moly GmbH, a Germany-based lubricant manufacturer, launched a new DEF anti-crystal additive concentrate for AdBlue. This product is designed to improve diesel engine efficiency while ensuring compliance with nitrogen oxide emission standards. It can be added directly to the AdBlue tank, providing a convenient way for vehicle owners to maintain the efficiency and longevity of their exhaust gas treatment systems. The concentrate helps prevent urea crystal formation and deposits that could block the AdBlue system, causing engine problems, and lowers the freezing point of the solution to around -16°C to protect against freezing in cold weather.

In March 2023, Saudi Aramco, a petroleum refinery company based in Saudi Arabia, acquired Valvoline Inc. for $2.65 billion. This acquisition supports Aramco's strategy to become a leading player in the integrated branded lubricants market, strengthening its presence in the premium sector and utilizing its production and R&D capabilities for future growth. Valvoline Inc., a US-based manufacturer, produces automotive maintenance products, including automotive diesel exhaust fluids.

Automotive diesel exhaust fluid (DEF) is a liquid used in diesel engines to lower harmful emissions. It consists of 32.5% urea, a compound derived from ammonia and carbon dioxide, and 67.5% deionized water. DEF is stored in a separate tank within the vehicle and is automatically injected into the exhaust system. This process is crucial for the effective operation of Selective Catalytic Reduction (SCR) systems and for meeting emissions regulations.

The main products in the automotive diesel exhaust fluid market include DEF itself, DEF pumps, and DEF tanks. Diesel Exhaust Fluid (DEF) is a clear, non-hazardous liquid used in diesel engines with SCR technology to reduce nitrogen oxide (NOx) emissions. It is available in various packaging options such as bottles, drums, intermediate bulk containers (IBCs), and bulk deliveries in sizes ranging from up to 10 liters to over 400 liters. DEF is utilized with technologies such as SCR and exhaust gas recirculation (EGR) and can be purchased through automotive company-operated stores, auto parts retailers, independent workshops, online platforms, and other distribution channels.
