Yes, changing engine oil once a year is usually acceptable, especially if you drive less than 10,000 miles annually. However, always refer to your vehicle's owner manual for the manufacturer's recommendations. Modern synthetic oils are designed to last longer without losing their protective properties, making annual changes viable for low-mileage driving. Yet, if you often drive in harsh conditions (e.g., extreme temperatures, towing, etc.), more frequent changes may be necessary to ensure your engine remains in peak condition.
