Key Takeaways:
- High-purity emission solutions reduce long-term maintenance costs by preventing damage to critical engine components such as injectors and SCR systems.
- A stable and flexible supply chain is crucial for maintaining operational continuity, particularly for fleets operating on tight schedules or under just-in-time delivery models.
- Improved fuel efficiency leads to measurable cost savings, particularly for businesses managing large fleets where small gains compound significantly.
- Compliance with local and international emissions standards protects against regulatory penalties and supports long-term sustainability goals.
Introduction
In Singapore’s transport and industrial sectors, diesel remains a critical driver. However, with tightening emissions regulations, engine compliance alone is no longer enough. That’s where Yara’s Air1 AdBlue diesel exhaust fluid makes a measurable difference. As a global leader in AdBlue production with a capacity of 2.8 million tonnes annually, Yara’s Air1 is produced using a unique “hot melt” process from ammonia and CO₂, distinct from fertilizer-grade urea. This process ensures a high-purity, precise formulation specifically engineered for Selective Catalytic Reduction (SCR) systems. It guarantees ISO 22241-1 compliance, consistent quality, and minimal contamination risk. Trusted by global OEMs such as Mercedes-Benz, Volvo, and Scania, Air1 delivers reliable performance at scale. As a supplier of Yara’s Air1, Mecpec provides a premium solution for operators focused on performance and emissions compliance.
SCR Systems Depend on Fluid Quality
SCR systems are designed to reduce nitrogen oxide (NOx) emissions, but their effectiveness depends entirely on the quality of the diesel exhaust fluid used. Lower-grade or improperly blended products can lead to:
- Crystallisation and system clogging
- Catalyst degradation
- Unplanned repairs exceeding SGD 15,000
Yara’s Air1 is engineered to avoid these risks by delivering:
- Verified ISO 22241-1 compliance
- Consistent formulation free from non-approved additives
- Compatibility with Euro VI engines and major OEM standards
For SCR systems to perform reliably, fluid quality is not optional—it’s essential.
Supply Stability is Operational Security
In fast-paced industries like logistics and construction, any disruption in supply can delay operations and reduce fleet availability. A reliable diesel exhaust fluid must be backed by infrastructure that supports uninterrupted access. Air1 offers:
- 10L, 200L, and 1,000L delivery formats
- Priority refill service during periods of high demand
- Responsive support and delivery scheduling through Mecpec
Unlike many general AdBlue suppliers, Air1 is supported by a global production network and distributed locally with fleet operations in mind.

Proven Efficiency Gains Across Fleets
The benefits of high-quality diesel exhaust fluid extend beyond emissions compliance. Proper SCR function can also lead to measurable fuel savings. With Yara’s Air1, you receive:
- Fuel savings of up to 6%, as reported in Singapore field trials
- Engine components that stay cleaner, reducing energy waste
- Performance that remains stable even under high-temperature, high-humidity conditions
These incremental improvements directly translate into lower fuel spending and reduced mechanical strain for fleets managing multiple diesel tanks and fuel points.
Compliance without Compromise
Environmental regulations in Singapore continue to evolve, placing greater responsibility on businesses to maintain strict emissions standards. Air1 supports:
- Compliance with Euro VI and LTA standards
- Consistent system performance across engine types
- Full traceability for smoother audits and inspections
As part of the nation’s network of oil trading companies, Mecpec ensures that Air1 is available with the documentation, support, and consistency required by regulated fleet operators. This gives businesses the confidence to meet compliance targets without operational disruption.
Cutting Costs May Cost You More
Lower-cost diesel exhaust fluid often brings hidden expenses. Inconsistent purity, non-compliant blends, and lack of OEM approval can all lead to:
- Increased fuel consumption due to poor SCR performance
- Injector or catalyst damage requiring costly repairs
- Frequent breakdowns and extended downtime
In contrast, Air1 offers:
- Certified protection for sensitive SCR systems
- Scalable supply with competitive pricing for fleets managing 50 or more tanks
- Long-term savings through reduced maintenance and fuel efficiency improvements
Investing in quality reduces risk and lowers the total cost of ownership.
