Petromin Fleet Master Plus SAE 20W-50 1L

Summary

Across mixed fleets, Petromin Fleet Master Plus SAE 20W-50 1L lubricates diesel and gasoline engines with API CI-4/SL certification. Under heavy loads, the 20W-50 viscosity grade maintains oil film thickness. This lubricant resists oxidation during extended operation in road dust and high temperatures.

Key Features

1. Extended Drain Interval: Through API CI-4/SL stability, the oil resists chemical breakdown. Keeps engines running longer between oil changes.
2. TBN Retention: With 10 mg KOH/g alkalinity, this fluid neutralizes acidic byproducts. Prevents internal corrosion from high-sulfur fuel.
3. High Flash Point: At a 230°C thermal threshold, the oil avoids evaporation. Maintains lubrication during extreme engine heat.
4. Viscosity Index: Under a 125 rating, oil flow stays consistent across temperatures. Protects components during cold starts and high-speed runs.
5. Cold Flow Performance: With a -24°C pour point, the oil remains fluid in cold weather. Prevents metal-on-metal friction during initial engine startup.

Frequently Asked Questions

Is Petromin engine oil good for diesel engines?

Yes, the CI-4 rating supports heavy-duty diesel performance. This lubricant handles soot and oxidation better than standard passenger car oils.

What is the benefit of the 20W-50 viscosity?

This grade adds a thicker protective film for high-mileage engines. It reduces oil consumption and mechanical noise in high-heat environments.
