Most companies test their oil before it goes in the bottle. Big deal. At Quaker State®, we test our oil after it’s gone through thousands of miles of real-world torture. And used Quaker State Advanced Durability still passes these critical tests for brand-new oil, even when it’s ready to be replaced.
Quaker State Advanced Durability motor oil:
• Minimizes friction-related wear 3x better than the wear standard set by top American and Japanese automotive manufacturers.*
• Meets or exceeds latest oil standards for protection under high temperature and severe service conditions.
