Engine Oil Does Not Last Forever:
No oil, whether synthetic or conventional, lasts forever. Even synthetic oil eventually degrades and loses its effectiveness due to factors such as high temperatures, oxidation, and contamination. The "once and forever" claim may give an impression that synthetic oil never needs changing, which is not true.
Oil Change Intervals:
Synthetic oils typically have extended drain intervals compared to conventional oils. However, these intervals are not unlimited and still require periodic changes as recommended by the vehicle manufacturer or based on specific driving conditions.
Importance of Oil Changes:
Regular oil changes, regardless of the oil type, are essential to maintain engine health, performance, and longevity. Changing oil helps remove accumulated contaminants, prevents sludge buildup, and ensures proper lubrication of engine components.
Benefits of Synthetic Oils:
Synthetic oils offer several advantages over conventional oils, including improved performance in extreme temperatures, reduced wear and tear, better resistance to oxidation and breakdown, and improved fuel efficiency. They can provide noticeable benefits during the recommended oil change intervals, but they do not eliminate the need for oil changes altogether.
In summary, while synthetic oil provides certain benefits and extended drain intervals, it does not last "once and forever" and still requires periodic changes. Regular maintenance and adherence to manufacturer-recommended oil change intervals are crucial for preserving the performance and lifespan of your vehicle.
