ATM 10W-30 Signature Series Synthetic Motor Oil

The AMSOIL Signature Series 10W-30 Synthetic Motor Oil is the top-tier offering from AMSOIL, engineered for enthusiasts seeking maximum protection and performance in all types of automotive gasoline engines. It combines industry-leading synthetic technology with premium additives to exceed the demands of modern engines, withstanding higher horsepower, heat, and complex emissions control systems. This oil is formulated to outperform conventional and other synthetic motor oils, providing long-lasting protection and performance. AMSOIL Signature Series Synthetic Motor Oil excels in protecting against engine wear by developing a strong fluid film and utilizing robust anti-wear additives, offering 75% more protection than industry standards in tests. It provides 100% protection against Low-Speed Pre-Ignition (LSPI) in advanced GDI and turbocharged engines, preventing potentially destructive spontaneous ignition events. Furthermore, its unique synthetic formulation is stable at high temperatures, offering outstanding protection against turbocharger coking, performing 72% better than required by the GM dexos1® Gen 2 specification in turbo coking tests. This motor oil offers extended drain intervals, guaranteed for up to 25,000 miles, 700 hours of operation, or one year, whichever comes first, in personal vehicles not operating under severe service. For severe service, the recommendation is up to 15,000 miles or one year. It is compatible with conventional and synthetic motor oils. While any brand of oil filter can be used, an AMSOIL Ea® Oil Filter is recommended to align with the extended drain intervals. However, modified engines, racing vehicles, and vehicles using alternative fuels are excluded from extended drain interval recommendations. Outside the U.S. and Canada, adhere to the vehicle manufacturer's recommended drain interval. Non-Ea oil filters must be changed according to their manufacturer's recommendations, even if the oil's 12-month service life remains intact.
