Synthetic oil is not recommended for some older vehicles due to compatibility issues with seals and gaskets, which can lead to leaks. High-performance vehicles specifically designed for synthetic oil or under severe driving conditions benefit the most. For regular cars, unless specified by the manufacturer, using synthetic oil can be overkill and more costly. Always consult your vehicle’s manual to determine the best type of oil.
