Engine oil grades are indicated by two numbers separated by a ‘W’ (e.g., 5W-30). The ‘W’ stands for winter, indicating the oil’s viscosity at colder temperatures, crucial for starting engines in cold weather. The first number (e.g., 5W) denotes viscosity when cold, with lower numbers flowing better in cold conditions. The second number (e.g., 30) indicates viscosity at operating temperature, with higher numbers being thicker. Thicker oil (higher viscosity) is better for older engines or extreme temperatures, while thinner oils improve fuel efficiency in newer engines. Always use oil grades recommended by your vehicle’s manufacturer, as they are tailored for engine design and operating conditions. Regularly checking and changing oil ensures optimal engine performance and longevity, following the guidelines in your owner’s manual for oil change intervals based on driving habits and conditions is essential for engine health.
