Different vehicles need different types of oil, and picking the right one makes a real difference in how your engine runs and how long it lasts. Motor oil comes in several grades and formulations—conventional, synthetic blend, and full synthetic—each with different properties and price points. Understanding what your vehicle actually needs helps you avoid overspending on oil you don't require or using something that won't protect your engine properly.
These articles walk you through the differences between oil types, what the numbers and letters on the bottle mean, and how to figure out which one your car calls for. You'll learn what each type costs, how long it lasts before needing a change, and whether switching between types is safe for your engine.
