Synthetic oil is a better alternative to conventional oil for several reasons. It lasts longer and provides better engine protection, improving the overall performance of your vehicle. Additionally, synthetic oil flows more easily in cold weather, reducing engine wear during startups. And, unlike conventional oil, synthetic oil doesn't break down as quickly, making it an excellent choice for vehicles that undergo frequent or extreme driving conditions. Recent studies by AAA have even shown that synthetic oil outperforms conventional oil. The study concluded that synthetic oil provided better engine protection and was more resistant to break down, making it the overall better choice for drivers.
