Why Can't You Go Back to Regular Oil After Synthetic

Switching from synthetic oil to regular oil is not recommended, and there are several reasons why this transition can be problematic. One of the primary concerns is the difference in the quality and formulation of synthetic and regular oils. Synthetic oils are designed with advanced chemical processes that create a more uniform and stable lubricant. They offer superior protection against wear and tear, better performance at high temperatures, and improved fuel efficiency. When you switch to regular oil, you lose these benefits, which can lead to increased engine wear and reduced performance.

Another issue is the compatibility of the oils. Synthetic oils are engineered to be compatible with modern engine designs, which often have tighter tolerances and more advanced components. Regular oils, on the other hand, may not meet the same standards and can cause issues such as increased sludge formation and deposits. These deposits can clog oil passages and reduce the effectiveness of the oil, leading to potential engine damage over time.

Furthermore, engine seals and gaskets are designed to work optimally with synthetic oils. Switching to regular oil can cause these seals to degrade more quickly, leading to leaks and other issues. Synthetic oils are less likely to break down under high heat and stress, which helps maintain the integrity of the seals. Regular oils, being less stable, can cause the seals to become brittle or soften, increasing the risk of leaks and other maintenance problems.

Lastly, the performance expectations of your vehicle are set when you use synthetic oil. Modern engines are often calibrated to perform best with synthetic oils, and switching to regular oil can result in a noticeable drop in performance. This can affect everything from fuel efficiency to acceleration and overall driving experience. To maintain the optimal performance and longevity of your engine, it is best to stick with the type of oil recommended by the manufacturer, which is often synthetic.
