Furthermore, some manufacturers specify low-viscosity oils, such as 0W-20, to improve fuel economy. The number after the dash indicates the oil’s thickness at operating temperature, with higher numbers providing a thicker film for protection under heat and stress.
Finding the Best Motor Oil Viscosity and Type for Your Car
Special Considerations for Modern Engines As automotive technology advances, the requirements for motor oil have become more specific. The API (American Petroleum Institute) service rating, denoted by letters such as SN, SP, or GF-6, signifies the level of detergent additives and protection against wear and deposits.
Observe the oil level, which should fall between the "Add" and "Full" marks. Many modern vehicles, particularly those with turbochargers or direct fuel injection, require full synthetic oils to handle the high temperatures and pressures generated by these systems.
Choosing the Right Viscosity and Performance for Your Car's Engine
Many modern vehicles, particularly those with turbochargers or direct fuel injection, require full synthetic oils to handle the high temperatures and pressures generated by these systems. Manufacturers design engines to perform optimally with a specific viscosity and performance standard, and they outline these requirements in the manual’s maintenance section.
