Quaker State QS-10W30 5QT Motor Oil, 10W-30, 5 qt Amber

Those first few miles after you pour brand new oil into your car, child's play. It's the thousands of miles of stop-and-go traffic, idling and extreme temperatures that are the true tests of toughness. These are exactly the tests that we put Quaker State® Advanced Durability™ motor oil through. In taxi fleets across North America, we test our oil to ensure it delivers even more protection. Quaker State® Advanced Durability™ proved it delivers twice the wear protection of the industry standard throughout its life.
