The recommended interval for oil changes can vary depending on factors such as the vehicle’s make and model, driving conditions, and the type of oil used. As a general guideline, it is common to change the engine oil every 5,000 to 7,500 miles or every six months, whichever comes first. However, it is essential to refer to your vehicle’s owner’s manual for the manufacturer’s specific recommendations, as some vehicles or synthetic oils may have extended oil change intervals.
