The amount of oil your car needs can vary depending on the make and model of your vehicle. The best way to determine the correct amount of oil for your car is to consult the owner's manual. The owner's manual will provide specific information regarding the recommended oil type, oil capacity, and other maintenance guidelines for your vehicle.
Typically, most cars require anywhere from 4 to 8 quarts of oil for an oil change, but again, this can vary depending on the engine size and design. It's important to use the correct type and amount of oil recommended by the manufacturer to ensure proper engine lubrication and performance. If you're unsure or don't have access to your owner's manual, you can also consult with a trusted mechanic or refer to online resources specific to your vehicle's make and model.
