Does engine oil exceeding six months have a significant impact?
2 Answers
Engine oil exceeding six months has a considerable impact. Here are the relevant details: Reason: If the engine oil has exceeded six months, it is recommended to replace it. Once oxidized, the sealing and lubricating properties of engine oil significantly decrease, and the most significant impact of reduced lubrication is severe engine wear. Additional information: If engine oil is not changed for an extended period, it will accumulate many impurities, such as iron filings and large dust particles, leading not only to wear issues but also to corrosion of internal components. Once the engine oil deteriorates and its performance declines, the lubrication properties of bearings and the cooling function of mechanical transmission parts will be lost, adversely affecting the vehicle's optimal driving condition.
Engine oil exceeding six months does have some impact. My old car was exactly like this - not changing the oil on time resulted in louder engine noise and rougher driving. Over time, engine oil oxidizes and deteriorates, reducing lubrication effectiveness while accumulating impurities and moisture. This accelerates internal engine wear and slightly increases fuel consumption. Especially with frequent city start-stop driving, the oil gets contaminated more easily. Remember to regularly check the dipstick - if the oil appears dark or overly viscous, it's no longer good. Safety first: it's recommended to change every six months or synchronize with mileage intervals, don't delay too long. Checking the dipstick yourself is simple, saving both hassle and money.
