What type of oil is suitable for Mitsubishi Outlander?
1 Answers
Outlander uses engine oil with a viscosity grade of 5W30. For oil changes, you can use mineral oil or semi-synthetic oil, or a 30-viscosity full synthetic oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The latter number represents the oil's kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as providing better lubrication performance under high-temperature conditions. The steps for changing the oil in an Outlander are as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow oil in the main oil passages to drain out. Use a specialized wrench to remove the oil filter. Apply oil to the seal of the new oil filter and tighten it clockwise by hand. Add new oil through the engine valve cover filler port—generally, fill up to three-quarters of the oil container. Start the engine and let it run for 5 minutes, then check for leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs. After stopping the engine, pull out the oil dipstick to ensure the oil level is within the standard range.
