{"product_id":"signature-series-5w-30-synthetic-motor-oil","title":"Signature Series 5W-30 Synthetic Motor Oil","description":"The AMSOIL Signature Series 5W-30 is a premium 100% synthetic motor oil designed to provide the absolute best engine protection. It creates a strong fluid film to keep metal surfaces separated, further reducing wear with robust anti-wear additives for maximum engine life. Independent testing shows it provides 75% more engine protection against horsepower loss and wear than required by industry standards, extending the life of vital components.\n\nThis advanced formulation offers 100% protection against Low Speed Pre-Ignition (LSPI), a critical concern for modern GDI and turbocharged engines. It also delivers superior turbocharger protection by resisting oxidation and neutralizing acids, with testing showing it protects turbochargers 72% better than required by the GM dexos1 Gen 2 specification. The oil features 50% more detergents than AMSOIL OE Motor Oil for exceptional sludge prevention, providing 90% better protection against sludge buildup.\n\nAMSOIL Signature Series Synthetic Motor Oil is designed for extended drain intervals, offering protection for up to 25,000 miles, 700 hours of operation, or one year, whichever comes first, in normal service. For severe service conditions, such as commercial use, excessive idling, or frequent towing\/hauling, the recommended interval is up to 15,000 miles. However, modified engines, racing vehicles, and vehicles using alternative fuels (E85, CNG, propane, etc.) are excluded from these extended drain interval recommendations. It is crucial to change the filter with every oil change, and for best performance, AMSOIL recommends using AMSOIL Oil Filters.\n\nThis motor oil is compatible with other conventional and synthetic motor oils, but mixing will reduce its performance benefits and shorten its service life. The use of aftermarket oil additives is not recommended with AMSOIL synthetic motor oils.","brand":"Amsoil","offers":[{"title":"Default Title","offer_id":52686927855928,"sku":"ASLQT-EA","price":13.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661658671.jpg?v=1784878570","url":"https:\/\/store.motormia.co\/products\/signature-series-5w-30-synthetic-motor-oil","provider":"MOTORMIA","version":"1.0","type":"link"}
