180 views

Car oil levels decrease primarily due to natural consumption as part of the engine's operation. Over time, high temperatures and engine wear can cause oil to evaporate or burn off, leading to a gradual decline. Small leaks or deteriorating oil seals can also result in oil losses. Regularly checking your oil level and following the manufacturer's recommended oil change intervals are crucial to maintaining engine health and preventing damage.
