Royal Purple HPS Synthetic High Performance Street 5W-30 Motor Oil - 1 Quart (Select 1989-2026)

Fits select 1989-2026 Acura, AM General, Aston Martin, Audi, and BMW vehicles. Royal Purple HPS (High Performance Street) motor oil is specifically formulated to maximize performance and meet the demands of high-performance and modified engines. This synthetic lubricant bridges the gap between traditional street oils and dedicated racing lubricants, making it suitable for both gasoline and diesel applications.

HPS is fortified with a significantly higher level of zinc and phosphorus anti-wear additives compared to standard oils, providing a robust barrier against metal-to-metal contact. It also features Royal Purple's proprietary Synerlec additive technology, which creates an ionic bond with metal surfaces to improve film strength and reduce friction. This results in better oxidation stability, reduced engine heat, and enhanced protection for critical components like camshafts and lifters.

• Proprietary Synerlec additive technology for increased oil film strength
• High levels of zinc/phosphorus (ZDDP) for superior anti-wear protection
• Optimized for both gasoline and diesel engine architectures
• Superior oxidation stability to prevent thermal breakdown
• Improved sealing between the piston ring and cylinder wall for maximum horsepower
