For drivers with high-mileage vehicles, 5w40 can be an excellent option. This dual-viscosity profile makes 5w40 a versatile choice for a wide range of climates and driving conditions.
While some high-mileage formulas are designed to be thicker, many 5w40 synthetics contain seal conditioners that help rejuvenate aging hoses and gaskets. Monitoring the oil level regularly and looking for signs of contamination, such as a milky appearance or metallic particles, is essential for engine health.
