How Often Should You Change Your Car's Engine Oil?
2 Answers
How often you should change your car's engine oil depends on the type of oil used. Mineral oil generally needs to be changed every six months or approximately every 5,000 kilometers; semi-synthetic oil should be replaced every 7 to 8 months or around 7,500 kilometers; and fully synthetic oil can last for about one year or 10,000 kilometers. The oil change intervals mentioned are only guidelines, and the actual frequency should be based on your vehicle's driving conditions. If you notice significant engine vibration or increased engine noise, you may consider changing the oil earlier. Engine oil is the lubricant used in engines, composed of base oil and additives. It serves multiple functions, including lubrication and wear reduction, aiding in cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption.
As a seasoned driver with over 20 years of experience, the frequency of oil changes should indeed be based on driving habits. Manufacturer manuals typically recommend every 5,000 to 10,000 kilometers or every six months, but I've found that frequent city driving in traffic or short trips with repeated starts can degrade oil faster, necessitating more frequent changes, say around 7,000 kilometers. Synthetic oil, being more resistant to high temperatures, can extend the interval to over 10,000 kilometers. Regular checks are crucial: after parking and turning off the engine for at least ten minutes, pull out the dipstick, wipe it clean, reinsert it, and check the oil level and color—the darker the color, the more contaminated the oil is, indicating it's time for a change. Neglecting this can accelerate engine wear, leading to repair costs far exceeding the price of an oil change. Remember, safety comes first; don’t skimp on small savings.
