We are delighted to announce an update to our OEM-approved TRUCK GUARD ELITE LS 5W-30 engine oil, now incorporating the latest DAF PSQL 2.1E LD specification. Designed to save on fleet costs, increase engine life, and reduce environmental impact.
DAF PSQL 2.1E LD is a lubricant specification standard set by DAF Trucks for the latest generation of commercial vehicles. This standard outlines stringent requirements covering viscosity, wear protection, temperature stability, and emissions system compatibility to ensure that a lubricant can be safely recommended for DAF engines in long-distance applications.
By achieving this specification, TRUCK GUARD ELITE LS 5W-30 not only meets but surpasses current expectations for the commercial sector, offering exceptional durability and efficiency for modern fleets. Furthermore, this specification sets a new benchmark for the market’s longest approved oil drain interval (ODI) of over 124,000 miles, marking a 33% increase over the closest OEM competitor.
The field-proven performance of TRUCK GUARD ELITE LS 5W-30 significantly reduces the need for frequent oil changes in commercial vehicles, lowering maintenance costs and minimising interruptions to fleet operations. This not only saves money but also lowers a fleet’s environmental impact. Likewise, the use of synthetic base stocks in our product ensure that it adheres to engine surfaces even when the vehicle is idle. Unlike traditional oils that settle, leaving engine parts unprotected, our synthetic formulation maintains a protective layer. Providing immediate lubrication right as the vehicle starts, reducing wear, and extending engine life.
TRUCK GUARD ELITE LS 5W-30 has OEM approvals including Scania LDF4, Mercedes MB 228.52 (DTFR 15C120) and MB 228.51 (DTFR 15C110), MAN 3677, VOLVO VDS 4.5, Renault RLD 3 and many other major manufacturers. These approvals in our product ranges emphasise Rock Oil’s dedication to innovation and quality, offering customers top-tier protection and performance for commercial vehicle fleets.
