Description

SOLAR CLASSIC SAE 50 is a high-performance mineral-based monograde engine oil, specially designed for heavy-duty diesel and gasoline engines operating in extreme temperature and high-load conditions. Formulated to meet API CF-4/SJ standards, this engine oil provides outstanding wear protection, superior thermal stability, and enhanced deposit control to ensure prolonged engine life and reliable performance.

With a robust detergent-dispersant additive package, this oil effectively prevents the formation of sludge, varnish, and soot, ensuring cleaner engines and extended service life. SOLAR CLASSIC SAE 50 is particularly suitable for older diesel and gasoline engines, heavy-duty commercial vehicles, and off-road equipment that require high-viscosity, monograde oils.
