PRODUCT DESCRIPTION Shell Rotella T Triple Protection Heavy Duty Engine Oil is a Energized Protection of Shell Rotella heavy duty diesel engine oils provides protection in three critical areas. Acid control helps protect against corrosion from acids formed as fuel burns and as the oil ages. Deposit control helps keep engine clean for optimum performance and long life. Wear control helps keep moving metal engine surfaces apart for long life. .COM 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 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. SAE This oil has a weight of SAE meaning it has an SAE viscosity rating of 15 in cold temperatures and a rating of 40 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. CONVENTIONAL MOTOR OIL This oil is a conventional motor oil meaning it is refined from crude oil or petroleum products. Conventional motor oils may or may not have additives included after refining. Conventional motor oils are more versatile than synthetic or hybrid motor oils because they are suitable for use with nearly all types of modern vehicle engines from cars and trucks to motorcycles ATVs farm equipment and more.
