What type of engine oil should be used for Toyota Highlander 2.0t?

[VonAdriana]

The original engine oil is suitable for Toyota Highlander 2.0t, with the oil grade being 0W-20. In terms of applicability, the original oil is more suitable for the engine. However, depending on different needs, engine oils can also offer other benefits such as noise reduction, fuel efficiency, and enhanced power performance. Therefore, you can also choose engine oils from brands like Mobil, Shell, and Castrol. 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, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value indicates better viscosity retention under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Toyota Highlander 2.0t is as follows: Wait for the engine temperature to cool down, 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 the oil in the main oil passages to drain out. Use a specialized wrench to remove the oil filter. Apply new oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add the new engine oil through the oil filler cap on the engine valve cover, typically filling up to three-quarters of the oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made. After stopping the engine, pull out the oil dipstick to ensure the engine oil level is within the standard range.
