You will see a code such as 5W-30 or 10W-40, where the number before the "W" indicates cold-temperature flow and the number after indicates viscosity at operating temperature. High-load conditions generate more heat, which can cause standard oil to shear down and lose its viscosity.
How Often to Change Car Oil Type and Maintain the Right Viscosity
Understanding the Viscosity Grade on Your Dipstick The first step to answering " what type of oil does my car take " is learning how to read the viscosity rating recommended by the manufacturer. Conventional oil is refined from crude oil and provides adequate protection for simple engines and low-mileage vehicles, but it breaks down faster under high stress.
Furthermore, certain manufacturers require specific certifications, such as those from API, ILSAC, or the European Automobile Manufacturers' Association (ACEA). Pull the dipstick out, wipe it clean, reinsert it fully, and then pull it out again to see the level.
How Often to Change Car Oil Type Based on Viscosity and Engine Needs
Similarly, if you live in a region with harsh winters, a lower cold-start rating (such as 0W or 5W) will ensure the oil flows quickly to protect the engine during ignition, while a higher summer rating prevents the oil from becoming too thin. Choosing the correct fluid for your engine is one of the most important decisions you will make as a car owner.
