SOLAR Classic Series Diesel Engine Oils SAE 40 API CH-4/SL

Description

SOLAR CLASSIC SAE 40 is a premium mineral-based monograde engine oil, specially formulated for heavy-duty diesel and gasoline engines operating in high-temperature and severe load conditions. Designed to meet API CH-4/SL specifications, this oil offers exceptional engine protection, superior thermal stability, and effective deposit control to enhance engine performance and durability.

With a high detergency and dispersant additive system, SOLAR CLASSIC SAE 40 helps prevent sludge, soot buildup, and wear, ensuring cleaner engines, longer service life, and reduced maintenance costs. It is particularly suitable for older diesel engines, off-road equipment, and commercial vehicles requiring monograde oils.
