Royal Purple 37140 HPS 10W-40 High Performance Synthetic Motor Oil 55-Gallon Drum

Royal Purple HPS (High Performance Street) SAE 10W-40 synthetic motor oil is specifically engineered for high-performance and modified engines that demand superior lubrication. Fortified with elevated levels of zinc and phosphorus (ZDDP) anti-wear additives and Royal Purple's proprietary Synerlec additive technology, HPS 10W-40 is designed to outperform both conventional and competing synthetic motor oils. This 55-gallon drum format is ideal for shops, fleet operations, and high-volume users.

Key Features:

• High Zinc/Phosphorus (ZDDP) Formula: Elevated anti-wear additive levels protect valve trains with flat tappet lifters, roller lifters, and aggressive high-lift/high-ramp-rate camshafts
• Synerlec Additive Technology: Royal Purple's proprietary technology responds to increased pressure with increased viscosity for enhanced metal-to-metal contact protection under severe operating conditions
• Reduces Heat and Wear: Advanced synthetic formulation significantly reduces friction-induced heat and wear to extend engine life
• Improved Ring Seal: Enhances sealing between piston rings and cylinder walls to maximize horsepower and torque output
• Exceptional Oxidation Stability: Resists breakdown at high temperatures, maximizing oil life and supporting extended drain intervals
• Advanced Synthetic Solvency: Reduces engine deposits and keeps internal components clean

Royal Purple HPS motor oil is recommended for vehicles no longer under the manufacturer's powertrain warranty and for enthusiasts seeking a higher level of engine protection and performance. For vehicles still under factory warranty, Royal Purple offers API-licensed oils. Available viscosities in the HPS line include 5W-20, 5W-30, 10W-30, 10W-40, and 20W-50.
