Motor oil is made from crude oil and is used to lubricate, clean, and cool engines. Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance.
This oil has a weight of SAE 10W-30, meaning it has an SAE viscosity rating of 10 in cold temperatures and a rating of 30 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle.
Full Synthetic Oil
This oil is a full synthetic oil, meaning crude oil is not used in making it. Synthetic oil can be used in vehicle engines instead of motor oils refined from crude oil, and often provides superior mechanical performance over traditional motor oil, including increased gas mileage and reduced engine wear at extreme temperatures. Its complex method of production means it can often cost more than conventional motor oil.
Mobil 1 10W-30 exceeds warranty requirements for gasoline engines where an API certified oil is specified. It meets: ILSAC GF-4 (API Certified - Starburst), API SM/SL, GM 6094M/GM4718M, Requirements for Diesel Powered Vehicles where an API CF or API CD is recommended and ACEA A1/A5, B1/B5. Mobil 1 10W-30 is recommended for all types of modern vehicles, including high-performance turbo-charged, supercharged gasoline and multi-valve fuel injected engines found in passenger cars, SUVs, light vans and trucks. Mobil 1 10W-30 is general purpose engine oil for all types of vehicles where a 10W-30 viscosity is recommended, but is not recommended for 2-cycle or aviation engines, unless specifically approved by the manufacturer. The Mobil 1's 10W-30 grade has a viscosity so popular amongst Do-it-Yourselfers. It provides excellent all season protection in a wide variety of vehicles. If you want total engine protection, excellent fuel economy and a product recommended for applications under warranty, you want Mobil 1. The world's leading synthetic motor oil, it features a proprietary SuperSyn anti-wear technology that provides performance beyond conventional motor oils. Technology that allows Mobil 1 to exceed the toughest standards of Japanese, European and U.S. car builders -- and to provide exceptional protection against engine wear, under normal or even the most extreme conditions.
