TikTok shows damaged Kia engine from poor maintenance

A TikTok mechanic showcased a severely damaged Kia engine, revealing it was still running despite heavy oil buildup. The video has gained over 214,800 views, highlighting the consequences of neglecting regular oil changes. Experts note that such extreme sludge buildup results from poor maintenance practices, including infrequent oil changes and low-quality oil. They recommend following manufacturer guidelines for oil changes to prevent engine damage. Viewers reacted with disbelief, many suggesting the engine had exceeded the recommended 10,000-mile oil change interval. Some criticized dealership recommendations, advocating for more frequent oil changes of every 3,000 to 5,000 miles.
