Petromin Petroshield-2

DESCRIPTION
Petromin Petroshield-2 Oil Series is trunk piston engine oil formulated for crankcase lubrication requirements of high-output trunk-piston diesel engines and other similar marine type applications. They are formulated from solvent-refined paraffin thermally stable base oils, combined with an effective additive package providing enhanced load-carrying ability, efficient oxidation stability and effective dispersancy/detergency. They provide effective acid neutralization and alkalinity retention in service, even where high-sulphur fuels are used.

APPLICATIONS

Petromin Petroshield-2 oil Series is primarily recommended for use in high-output trunk piston marine diesel engines operating on medium residual fuels (sulphur upto 2.0%). They are suitable for four-stroke cycle engines.


BENEFITS

• Neutralize combustion acids.

• Maintain alkalinity in service.

• Good demulsibility.

• Control ring and liner wear.
