Quaker State® Enhanced Durability Synthetic Blend Motor Oil provides:
• Excellent protection against friction-related wear*
• Improved resistance to engine stress at high RPMs and under heavy loads**
• Enhanced resistance to thermal and viscosity breakdown
• Excellent lubrication at low and high temperatures
