What is the replacement interval for conventional mineral oil in cars?
4 Answers
Conventional mineral oil should be replaced every 5,000 kilometers. Mineral oil experiences greater performance degradation in later stages, provides reduced engine protection, and may increase overall vehicle fuel consumption. Additionally, mineral oil has a shelf life and becomes ineffective after six months. Here are the replacement intervals for different types of engine oil: 1. Engine oils are generally categorized into three types: full synthetic, semi-synthetic, and conventional mineral oil. 2. Full synthetic oil typically requires replacement every 10,000 kilometers or 1 year. 3. Semi-synthetic oil usually needs replacement every 7,500 kilometers or 7-8 months. 4. Conventional mineral oil should be replaced every 5,000 kilometers or 6 months.
Generally, it is recommended to change mineral oil every 5,000 kilometers or every 6 months, whichever comes first. I've been using conventional oil for many years and feel that if you often drive short distances in the city or get stuck in traffic frequently, the oil tends to accumulate dirt, so it's better to shorten the interval to every three or four months. If you're driving on highways daily in a cleaner environment, you might extend it to seven or eight months. Also, remember to check the owner's manual, as different vehicle models have varying requirements. Don't forget to inspect the color change on the dipstick; if it turns cloudy, it's time for a change. Compared to synthetic oil, which lasts longer, mineral oil is more affordable, so I choose it to save money. Remember, changing the oil on time protects the engine, extends the vehicle's lifespan, and saves on repair costs.
I use a lot of mineral engine oil, with an oil change interval of around 5,000 kilometers, but it really depends on the actual driving conditions. For example, when I frequently carry heavy loads and drive on mountain roads with lots of dust and high temperatures, the oil deteriorates faster, so I change it every four months. For regular commuting with less driving, it can be stretched to six months. Temperature also has a big impact—oil viscosity drops faster in the hot summer, and cold starts are harder in winter, so early changes are recommended. It's best to develop a habit of checking the oil level every month and topping it up if it's low. Older cars tend to burn oil more easily, so they require more frequent maintenance. Don’t follow others who use synthetic oil and stretch the intervals—mineral oil is cheaper but needs more frequent changes. Also, replace the oil filter with every oil change to keep the engine much cleaner.
The replacement interval for mineral oil is typically every 5,000 kilometers or 6 months. I recommend adjusting it based on your driving habits, such as changing it earlier in heavy city traffic where the oil gets dirty faster. Regularly checking the color and viscosity changes of the oil is crucial. Remember to choose the correct viscosity grade that matches your engine when changing the oil.
