How Often Should Engine Oil Be Changed Normally?
2 Answers
Different brands and models have varying requirements, but for passenger cars, the engine oil is typically changed between 5,000 to 10,000 kilometers. Additionally, apart from the mileage requirement, there is also a time limit for maintenance. The engine oil should not be used for more than one year. Below are the relevant details: Maintenance: Overall, as long as either the time or mileage indicator is met, maintenance must be performed. Oil Change: The oil change interval depends not only on mileage and time but also on the type of oil being used. Oil Change Intervals: Different types of engine oil have different change intervals. For example, mineral oil should be changed within 5,000 kilometers, semi-synthetic oil within 8,000 kilometers, and full-synthetic oil within 10,000 kilometers.
How often should engine oil be changed? It really depends on your driving habits. After driving for over 20 years, I've learned it's not about fixed intervals. New car manuals typically recommend every 5,000 to 10,000 kilometers or every six months to a year. But if you frequently drive long distances on highways, using full synthetic oil can safely extend the interval to 12,000 kilometers. However, if you're often stuck in city traffic with heavy engine load, changing at 5,000 kilometers is necessary—no shortcuts here. I make it a habit to regularly check the dipstick; if the oil turns black or shows sediment, don't delay the change. Timely oil changes significantly extend engine life—don't wait until smoke appears. Seasonal changes also matter: frequent cold starts in winter degrade oil faster, while summer heat accelerates evaporation. Choosing a reputable oil brand is crucial, as durability varies by brand. Bottom line: don't just rely on the manual. Regular inspections save money and ensure safety. Averaged out, spending a little monthly on maintenance beats costly engine overhauls by far.
