A lower number like 5W means the oil flows more easily when the engine is cold, ensuring critical protection during startup. You can find the precise recommendation in the owner's manual, usually located on the oil fill cap or in the maintenance section.
Avoiding the Wrong Car Oil and Its Costly Consequences
With countless options on the shelf, selecting the incorrect viscosity or performance grade can lead to reduced efficiency and costly repairs. Environmental and Longevity Considerations.
Automakers specify criteria such as API (American Petroleum Institute) service categories or ILSAC (International Lubricant Standardization and Approval Committee) standards. Modern engines are often designed with specific viscosity requirements to balance fuel economy and performance, making this the most crucial factor to check.
Avoiding the Wrong Viscosity and Performance Grades
Decoding the Viscosity Rating The first number you see on a bottle, such as 5W-30 or 10W-40, refers to the oil's viscosity, or its resistance to flow. The lubricant flowing through your engine reduces friction, manages heat, and protects moving parts from wear.
