Petromin Fleet Master Plus SAE 20W-50 15L provides lubrication for diesel engines under heavy thermal loads. From its API CI-4 rating, this lubricant maintains viscosity despite high road dust and humidity. For large-capacity sumps, the 15L volume fits mixed fleet operations.
Key Features
- Extended Drain Interval: Chemical stability resists thermal breakdown over long durations. Reduces oil change frequency during high-mileage operations.
- High TBN Retention: Acid-neutralizing additives remain active throughout the service life. Stops corrosion when using high-sulfur diesel.
- Soot and Deposit Protection: Dispersant molecules prevent carbon buildup on pistons and rings. Prevents power loss from internal sludge.
- Oxidation Control: High-temperature resistance prevents oil thickening and varnish formation. Maintains flow during peak operating temperatures.
- Mixed Fleet Compatibility: Lubricant meets CI-4/CH-4 and SL service specifications. Simplifies inventory for multi-engine fleet operators.
