what type of oil does my car take

Popping the hood to check your oil is a simple act of car care, but when it’s time for an oil change, a common question arises: what type of oil does my car take? Using the wrong oil can affect your engine’s performance and longevity. It’s not a one-size-fits-all situation, but finding the right answer is easier than you might think.

The Easiest Ways to Find Your Car’s Perfect Oil Match

Before you guess, check your owner’s manual. It’s the definitive guide written by the people who built your car, and it will specify the exact oil viscosity and performance standards required. If the manual is long gone, don’t worry. Your vehicle’s oil filler cap often has the recommended viscosity printed right on it. You can also use online tools from major oil manufacturers; just input your car’s year, make, and model for an instant recommendation.

Decoding the Numbers on the Bottle

You’ve likely seen codes like 5W-30 or 0W-20 on oil bottles. This is the oil’s viscosity grade, essentially its thickness. The number before the “W” (for Winter) shows how the oil flows in cold temperatures—a lower number means better cold-weather starting. The number after the dash indicates how thick the oil is at your engine’s normal operating temperature. Using the viscosity recommended by your manufacturer ensures optimal lubrication and protection in all conditions.

Conventional vs. Synthetic: Making the Right Choice

You’ll also need to choose between conventional and synthetic oil. Conventional oil is a refined petroleum product, while synthetic oil is engineered in a lab for superior performance. Synthetic oils generally provide better engine protection, perform better in extreme temperatures, and can last longer between changes. Many modern cars, especially those with turbocharged engines, require synthetic oil. Check your manual to see if it’s recommended or required for your vehicle.

Taking a few minutes to confirm the correct oil for your car is a small task with a big payoff. It protects your engine, maintains your warranty, and provides peace of mind for every mile ahead. Your car—and your wallet—will thank you for it in the long run.
