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

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.
