Rex 5W-30 Full Synthetic Engine Oil

Rex 5W-30 Full Synthetic Engine Oil

Rex 5W-30 Full Synthetic Engine Oil is formulated with premium full-synthetic base oils and an advanced additive system to deliver exceptional wear protection, engine cleanliness, and thermal stability. Built for today’s high-output, fuel-efficient gasoline engines—including many turbocharged and GDI (gasoline direct injection) designs—it provides rapid lubrication at start-up and a strong, stable film at high operating temperatures to help maximize engine life and performance.

Key Features & Benefits

Full Synthetic Performance
Provides superior protection versus conventional and synthetic blend oils, with excellent low-temperature flow and high-temperature stability.

Advanced Wear Protection
Helps protect critical engine components—such as camshafts, bearings, and piston rings—from metal-on-metal contact, even under heavy loads and high RPM.

Clean Engine Operation
Powerful detergents and dispersants help control sludge, varnish, and deposits, keeping engines cleaner for smoother, more consistent performance.

Turbo & GDI Friendly
Engineered to withstand the high temperatures and stresses common in turbocharged and gasoline direct injection engines, helping reduce deposit formation and LSPI risk.

Fuel Efficiency Support
Optimized 5W-30 viscosity helps reduce internal friction for efficient operation, while still maintaining a durable oil film for lasting protection.

Oxidation & Thermal Stability
Resists breakdown and thickening under severe conditions, helping maintain viscosity, protection, and oil life throughout the drain interval.
