Petromin Fleet Master LD SAE 15W-40 3L provides lubrication for heavy-duty diesel and gasoline engines. This multi-grade fluid maintains API CH-4/SJ standards across mixed fleet operations. High TBN levels neutralize combustion acids during extended drain intervals.
Key Features
- API CH-4 Performance: Meets API CH-4/SJ standards for mixed commercial fleets. Wear protection stays active under high-load conditions.
- TBN Retention: High Total Base Number (TBN) chemical composition. Acid neutralization works even with high-sulfur diesel fuel.
- OEM Approvals: Carries certifications from Volvo, Mercedes-Benz, and MAN. Complies with strict factory requirements for heavy-duty vehicle models.
- Oxidation Control: Resists thermal breakdown and sludge formation. Stops deposit buildup despite intense engine heat and road dust.
- Soot Protection: Anti-varnish additives manage carbon soot particles. Clean engine internals maintain necessary compression levels.
Frequently Asked Questions
Is Petromin 15W-40 good for diesel engines?
This oil meets API CH-4 specifications specifically for diesel performance. Heavy-duty truck engines maintain stability under high-pressure environments with this lubricant.
What is the benefit of high TBN in this oil?
High TBN neutralizes corrosive acids that combustion produces. This permits longer intervals between oil changes without risking internal engine damage.
