COGENT RYDER SUPERIOR 20W-50 SL/CF SERIES
COGENT RYDER SUPERIOR 20W-50 Multigrade Gasoline and Diesel Engine Oil | API SL/CF
Product Description :
COGENT RYDER SUPERIOR 20W-50 SL/CF SERIES is a premium multigrade gasoline and diesel engine oil formulated with high-quality base stocks and an advanced technology additive system. This high-performance conventional motor oil is designed to provide an excellent level of defense and performance, working significantly harder than standard lubricants by continuously preventing harmful dirt, soot, and sludge build-up while noticeably reducing engine noise.
This versatile 20W-50 lubricant meets the strict engineering standards of most global passenger car manufacturers. It is ideally suited for both gasoline and diesel powertrains—whether naturally aspirated or turbocharged—and is fully adapted for modern vehicles equipped with catalytic converters running on unleaded fuel. By maintaining stable oil film thickness under high-temperature loads and minimizing wear during severe stop-and-go driving, it ensures optimal engine cleanliness, component reliability, and extended hardware life
Features & Benefits :
• Superior protection against viscosity and thermal breakdown.
• Excellent detergency and dispersancy.
• Superior sludge protection for greater engine reliability.
• Enhanced wear protection and improved engine cleanliness.
• Easier cold starts and improved fuel economy compared to mono-grade engine oils.
