Rock Oil conducted a rigorous six-month field trial with a long-term fleet customer seeking to enhance their efficiency to evaluate the real-world performance of TRUCK-GUARD ELITE LS 5W-30, a next-generation lubricant designed for modern commercial vehicle fleets, which now meets the DAF PSQL 2.1E LD specification.
The study revealed significant improvements in operational efficiency, cost management, and environmental sustainability with reduced environmental impact for long-distance commercial vehicle fleets
What is DAF PSQL 2.1E LD?
The DAF PSQL 2.1E LD specification outlines rigorous performance standards set by DAF Trucks for lubricants used in modern commercial vehicles. Lubricants compliant with this standard must meet demanding criteria related to viscosity, wear protection, temperature stability, and compatibility with emissions systems, ensuring safe and efficient use in DAF engines during extended operations.
Trial Objectives and Methodology
The primary objectives of the trial were to:
- Compare lubricant consumption between TRUCK-GUARD ELITE LS 5W-30 and the incumbent lubricant.
- Assess potential financial savings.
- Evaluate impacts on engine wear, operational longevity, and waste generation.
A six-month controlled trial involved 50 vehicles divided into two groups of 25 each, one using the existing lubricant and the other using TRUCK-GUARD ELITE LS 5W-30. Researchers closely monitored critical performance metrics, including:
- Total lubricant consumption
- Maintenance costs
- Engine wear
- Oil drain interval efficiency
- Environmental impact
- Lubricant performance regarding engine wear
Key Findings
Lubricant Consumption and Cost Efficiency
- Lubricant-related expenditure was reduced by 40%.
- Vehicle downtime associated with oil changes decreased by 40%.
- Improved lubrication performance, particularly during engine startup, significantly reduced wear, resulting in lower overall maintenance costs and extended engine lifespan.
- Reduced vehicle downtime translated directly to cost savings for fleet operators.
Environmental Impact
The trial demonstrated several environmental advantages of adopting TRUCK-GUARD ELITE LS 5W-30:
- Reduced Oil Consumption: Extended oil-drain intervals led to fewer oil changes and thus decreased total oil usage.
- Less Waste Oil Generation: Longer intervals between oil changes significantly lowered the amount of hazardous waste needing disposal.
- Lower Carbon Footprint: Reduced frequency of oil changes meant fewer resources consumed during production, transport, and disposal, resulting in decreased emissions.
- Decreased Packaging Waste: Lower oil consumption directly reduced manufacturing and disposal of packaging materials, filters, and containers.
- Lower Energy Usage: Extended drain intervals minimised the energy-intensive processes of refining, distributing, and disposing of lubricant oils.
Trial Performance Results
Throughout the six-month study, the condition-based analysis revealed vehicles using TRUCK-GUARD ELITE LS 5W-30 exhibited significantly lower engine wear compared to vehicles running on the existing lubricant, clearly indicating superior lubricant performance.
Customer Feedback
Feedback from the participating fleet was overwhelmingly positive, highlighting:
- Rock Oil provides exceptional service and operational support.
- Noticeably superior lubrication performance.
- Significant reductions in fleet operating costs.
- Fewer operational disruptions and maintenance requirements.
Conclusion
The results from this comprehensive field trial confirm that TRUCK-GUARD ELITE LS 5W-30 lubricant delivers substantial benefits in efficiency, maintenance cost reduction, and sustainability. Rock Oil’s innovative lubricant technology helps commercial fleet operators achieve:
Extended drain intervals, reducing oil-change frequency
Lower maintenance and operational costs
Minimised vehicle downtime
For fleet operators seeking a competitive edge, TRUCK-GUARD ELITE LS 5W-30 offers a proven pathway to improved performance and sustainability and a environmentally sustainable lubricant solution for commercial vehicle fleets seeking enhanced performance and long-term operational savings.
Methodology Note: The study was conducted using a controlled, scientific approach, with careful monitoring and analysis of performance metrics across a representative fleet sample.
