High-zinc motor oil
29/11/11
Quaker State has developed a new motor oil, specifically for high-output, flat-tappet engines. Quaker State Defy contains a high level of ZDDP, an anti-wear additive commonly referred to as zinc, which combats friction, wear and oxidation. We as an industry have seen the levels of zinc in motor oil consistently reduced in each successive gasoline engine specification implemented by ILSAC in the past few years, says Jeff Hsu, Quaker State technology specialist. This reduction of zinc is fine for drivers of newer vehicles, but is leaving classic car owners, enthusiasts and those with flat-tappet cams and followers with fewer and fewer options in the motor oil category. He says the proprietary low-volatility ZDDP technology used in Quaker State Defy motor oil significantly reduces the amount of volatile phosphorus, while retaining its anti-wear protective behavior and antioxidant performance. An additional benefit of the new, fully formulated Quaker State Defy motor oil is that it is capable of running a full manufacturer-recommended drain interval during engine break-in and does not need to be drained after five hundred or a thousand miles, like some high-zinc break-in oils. Quaker State Defy is also intended for use in higher-mileage passenger vehicle engines, and helps control the wear that high-mileage engines typically endure.
