How many kilometers should Jinjiahua engine oil be replaced?

Jinjiahua is a mineral engine oil that needs to be replaced after driving approximately 8,000 to 10,000 kilometers. Jinjiahua engine oil: Suitable for mid-to-high-end and light turbocharged engine models. Compatible with catalysts to reduce emissions. Jinjiahua focuses on anti-wear and anti-sludge properties, but its durability and cleaning performance are not as strong as other engine oils in the same price range. Under high-temperature and high-load conditions, it provides excellent engine protection, but the cost is higher. Classification of engine oil: Mineral oil, directly refined from petroleum. Synthetic oil, refined from crude oil or coal to produce ethylene, with stable physical and chemical properties and a higher viscosity index than ordinary mineral oil. Semi-synthetic oil, a blend of mineral oil and synthetic oil in a certain proportion. Methods to identify fake engine oil: Check the packaging, inspect the oil cap and sealing ring. If the cap is rough and lacks an "easy-open" seal, it may be adulterated or inferior oil. Smell the oil; genuine oil has no pungent odor, while fake oil has a strong, pungent smell. Touch the oil; genuine oil has low viscosity at room temperature, while fake oil feels stickier. Observe the color; imported oil is yellow and transparent, while domestic oil is light blue. Pour it on A4 paper; if it doesn't leak, it's high-quality oil.
As a mineral oil type, Jinjiahua engine oil is generally recommended to be replaced every 5,000 to 7,500 kilometers, which is a conclusion drawn from my years of car usage experience. Having driven various older models, if it's just for short urban commutes with occasional weekend trips, changing at 7,500 kilometers is fine. However, don't forget to check the vehicle manual, as some models have stricter requirements. I have an old car that has been using Jinjiahua for a long time, and I make it a habit to check the oil color and viscosity every two months. If it turns black or shows sediment, it indicates aging, and even if the mileage hasn't been reached, it should be replaced early. Otherwise, increased engine friction will lead to louder noises. In high-temperature weather or frequent congested driving conditions, the oil's lifespan shortens, and it's best to change it closer to 5,000 kilometers. Developing good habits can save you from costly major repairs.
As an automotive enthusiast, I've tested the performance of JINJIAHU motor oil and found it suitable for most family cars, with an optimal oil change interval between 5,000 to 7,500 kilometers. For daily driving, the oil needs to provide wear resistance and cooling properties. On highway long-distance trips, you can stretch the interval to 7,000 km, but if you frequently accelerate aggressively or carry heavy loads, the oil oxidizes more easily - in such cases I recommend sticking closer to 5,000 km. For my own compact car that commutes hundreds of kilometers weekly, I track the mileage using my phone and change the oil every 5,000 km while checking for tank leaks. Regular oil changes not only protect the engine and ensure smoother operation, but also prevent sudden breakdowns - it's a cost-effective maintenance practice that brings peace of mind. Don't procrastinate too long on this crucial maintenance task.
