COGENT PLASMA SUPERIOR 15W-40 SL SERIES
COGENT PLASMA SUPERIOR 15W-40 Multigrade Engine Oil | API SL/CF
Product Description :
COGENT PLASMA SUPERIOR 15W-40 SL SERIES is a premium multigrade gasoline and diesel engine oil advanced formulated to protect passenger cars and light-duty commercial vehicles. Blended from high-quality base stocks and fortified with an advanced technology additive system, this robust 15W-40 motor oil delivers a high level of wear defense, exceptional deposit control, and long-lasting thermal stability.
This high-performance engine oil works harder than other conventional motor oils by continuously preventing dirt, soot, and sludge buildup while actively reducing engine noise under severe driving conditions. By maintaining an optimal oil film thickness under heavy loads and high operating temperatures, it secures critical engine components against mechanical friction, prevents viscosity breakdown, and supports greater hardware reliability across both naturally aspirated and turbocharged systems.
