Synthetic oil does cost more per oil change, but it offers several benefits that often make it worth it over time. Synthetic oil is engineered to handle high heat and cold temperatures better, resist breaking down, and keep your engine cleaner than conventional oil. Because synthetic oil lasts longer, many vehicles can safely go farther between oil changes, which can help offset the higher price. Synthetic oil can also provide better protection for turbocharged engines, vehicles used for towing, or cars driven in extreme climates. For many drivers, especially with newer vehicles, the added engine protection and longer service intervals make synthetic oil a smart investment.
