How to Optimize Engine Life with High-Performance Fleet Lubricants
Maximize your fleet uptime and reduce maintenance costs with advanced API CI-4 and CJ-4 engine oils designed for modern diesel engines.

Reducing Sludge and Oxidation


Modern diesel engines operate at higher temperatures than ever before. This causes standard oils to oxidize rapidly, forming sludge that clogs filters. High-performance fleet oils utilize premium base stocks that resist oxidation by up to 50% more than conventional mineral oils.

TBN: Your Fleet's Shield


Total Base Number (TBN) measures the oil's ability to neutralize acidic combustion byproducts. For long-haul trucking, maintaining a high TBN is essential to prevent corrosive wear on cylinder liners and bearings.

The ROI of Quality


While premium oil costs more per liter, the extension of drain intervals from 15,000km to 25,000km significantly reduces the Total Cost of Ownership (TCO) for any logistical operation.
