AMSOIL Series 2000 20W-50 Synthetic Racing Oil clings tenaciously to engine surfaces, so it shields engines from start-up wear. Further enhancing wear protection, AMSOIL Series 2000 20W-50 Synthetic Racing Oil's wax-free lubricating basestocks assure rapid post-start-up lubrication. AMSOIL Series 2000 20W-50 Synthetic Racing Oil contains powerful corrosion preventives, detergents, dispersants and anti-foam agents to protect engines from the harmful effects of water, acids, debris, deposit-forming materials and air entrained oil. Boosts Power, Speed and Efficiency AMSOIL Series 2000 20W-50 Synthetic Racing Oil reduces friction so effectively that virtually none of the engine's power is wasted on "drag." Its extraordinary formulation gives Series 2000 a coefficient of friction lower than that of other fine, race-formulated synthetic oils. With Series 2000, vehicles accelerate fast, attain top speeds and use fuel efficiently. Maintains Integrity in Demanding Conditions AMSOIL Series 2000 20W-50 Synthetic Racing Oil maintains a constant high level of performance over time because it resists the damage many oils undergo in high temperature, intense shearing force conditions. Advanced thermal stability allows AMSOIL Series 2000 20W-50 Synthetic Racing Oil to circulate readily, thus protecting hard-to-reach areas that heat-damaged oils grow too thick to reach. Superior shear stability allows AMSOIL Series 2000 20W-50 Synthetic Racing Oil to provide a dependable pad of protection between parts even after exposure to shearing forces that tear lesser oils apart. Mixing AMSOIL AMSOIL Series 2000 20W-50 Synthetic Racing Oil may be mixed with petroleum-based oils or with other synthetic oils. However, a mixture of AMSOIL Series 2000 20W-50 Synthetic Racing Oil and another oil may offer a shorter service life than pure AMSOIL Series 2000 20W-50 Synthetic Racing Oil does. The AMSOIL Product Warranty does not apply to mixtures of AMSOIL Series 2000 20W-50 Synthetic Racing Oil and other oils. Service Life Non-turbo-charged, non-race gasoline engines: Change the oil at intervals up to three times longer than recommended by the manufacturer, or one year, whichever comes first. Turbo-charged, non-race gasoline engines: drain oil at intervals up to three times longer than those recommended by the engine manufacturer, or six months, whichever comes first. Race engines: Specified by Owner Experience/Oil Analysis. Marine four-cycle gasoline engines and infrequently used automotive four-cycle gasoline engines: drain oil at intervals up to three times longer than those recommended by the engine manufacturer, or one year, whichever comes first. Gasoline four-cycle fleet vehicle engines: drain oil at intervals up to two times as long, or six months, as engine manufacturer's recommendations if the findings of a conscientiously applied program of used oil analysis indicate the oil remains serviceable. AMSOIL Full-Flow Oil Filters should be changed at 12,500-mile or six-month intervals, whichever comes first, in gasoline engines. If a Hastings or other filter is used, filter should be changed at manufacturer recommendations. |
