This portion of the car oil viscosity chart measures the oil's thickness and its ability to maintain a protective film under heat and stress. Higher numbers, such as 30 or 40, indicate a thicker oil that creates a stronger lubricant barrier but may slightly reduce fuel economy in colder climates.
Car Oil Viscosity Chart Summer: Choosing the Right Viscosity for Warm Weather
Drivers in regions with harsh winters often benefit from a lower winter rating to ensure easy cold starts. These oils are less prone to oxidation and shear breakdown, meaning they maintain their viscosity longer than conventional oils.
The "W" stands for Winter, and the number preceding it indicates the oil's cold-weather viscosity. Using an oil that is too thin can cause excessive metal-to-metal contact, while oil that is too thick can starve the engine of oil, leading to overheating and sluggish performance.
Car Oil Viscosity Chart for Summer Conditions
Selecting the wrong grade can lead to increased wear, reduced fuel efficiency, and even premature engine failure, making this specification one of the most critical in your maintenance routine. In reality, using a 10W-60 in a engine designed for 5W-20 can cause the engine to work harder, reducing power and increasing emissions.
