This engine oil needs to be changed every 5,000 kilometers. Below is additional information: 1. Jin Jia Hu 10W40: Jin Jia Hu 10W40 oil is a semi-synthetic oil, suitable for minimum temperatures of minus 25 degrees Celsius. In colder regions during winter, it is advisable to switch to 5W oil, which offers better low-temperature fluidity and cold-start performance. It also has good high-temperature stability and sealing properties, preventing oil burning in the combustion chamber, making it suitable for older vehicles. 2. Functions: Jin Jia Hu 10W40 features dual-action cleaning, containing a dual-action cleaning formula that cleans sludge while preventing its reformation. It provides anti-wear protection, offering excellent protection under both high and low temperatures, thereby extending the engine's lifespan. It helps reduce the consumption of both oil and fuel. Additionally, it aids in cooling by transferring heat back to the oil tank and then dissipating it into the air to cool the engine.

I've been driving for over twenty years and always feel that for oils like Jinjiah 10w40, changing it every 5,000 to 8,000 kilometers is the safer bet. This is mainly because it's a mineral oil type, not as durable as full synthetic oils, especially in urban stop-and-go traffic where frequent starts and stops can cause the oil to degrade more quickly, leading to increased engine noise or higher fuel consumption. Regularly checking the dipstick is also a good habit—if you notice the oil turning black or losing viscosity, it's time for a change. For older vehicles, those frequently carrying heavy loads, or operating in harsh environments like dusty roads, you might need to change it as often as every 5,000 kilometers. Don't skimp on this small expense; delaying too long can lead to much higher engine repair costs. Personally, I make it a habit to visit the repair shop every six months or so for a check-up to ensure my car runs safely and smoothly.

As a daily commuter, I believe the oil change interval for Jinjiahu 10w40 largely depends on driving habits. I'd recommend changing it around 6,000 km. The 10w40 viscosity suits most daily drivers, but it can last up to 8,000 km if you frequently drive on highways or leave the engine idling often. Conversely, with heavy city traffic and stop-and-go conditions accelerating oil degradation, a 6,000 km change is necessary. Regularly checking oil level and cleanliness is crucial—don't just rely on mileage. I keep track of maintenance alerts while logging mileage and have learned that oil life is affected by temperature—frequent cold starts in winter cause more wear. Also, check your new car's manual for specific recommendations to avoid unnecessary waste.

I've seen many cars develop issues due to missed oil change intervals, so it's best not to exceed 7,500 km with oils like Jinjiahu 10w40. The primary functions of engine oil are lubrication and rust prevention. When deteriorated, insufficient lubrication can wear down engine components, leading to failures. Driving conditions vary: long highway trips can easily stretch to 8,000 km, but frequent braking in urban short-distance driving requires changes at 6,000 km. The 10w40 designation indicates a wide viscosity range suitable for all seasons. Remember to check the filter during oil changes and replace it if aged. From a personal safety perspective, changing oil earlier saves money and peace of mind.
