Using an incorrect viscosity can lead to poor performance, increased wear, or even damage to the emission control systems. High Mileage Formulations For drivers with vehicles that have accumulated significant distance, specialized high-mileage multigrade oils are available.
Multigrade Oil Vs Single Grade: Performance, Protection, and Efficiency Compared
This versatility is achieved through a sophisticated blend of base oils and viscoelastic additives, commonly referred to as viscosity index improvers, which allow the oil to flow smoothly at low temperatures while maintaining adequate film strength at high operating temperatures. The Role of Synthetic Technology.
Vehicle owners must always consult the owner's manual to determine the manufacturer's recommended viscosity grade and performance specifications. Furthermore, because they are designed to shear back to a stable viscosity, they maintain their efficiency throughout the oil change interval.
Multigrade Oil Vs Single Grade: Performance, Protection, and Efficiency Compared
These specifications, such as API SP or ACEA C6, ensure that the oil provides the necessary protection for specific engine designs, including turbochargers and direct injection systems. Fuel Economy and Emissions The adoption of low-viscosity multigrade oils, such as 0W-16 or 5W-20, has been a major factor in helping the automotive industry meet stringent fuel economy standards.
