What grade of engine oil is suitable for the Leiling 1.2T?

[EvanDella]

Toyota Leiling 1.2T engine originally uses 5W-30 engine oil. If you want to change the engine oil during later maintenance, you can use SAE 0W-20, 5W-20, or 5W-30 engine oil. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -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. The higher the number, the better the oil can maintain viscosity at 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 Leiling 1.2T is as follows: Wait for the engine temperature to drop, allowing the oil to flow back to the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan 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 passage to drain out. Use a special wrench to remove the oil filter. Apply engine oil to the seal of the new oil filter and tighten it clockwise by hand. Add new engine oil through the oil filler cap on the engine valve cover, usually filling about three-quarters of the bottle. Start the engine and let it run for 5 minutes, checking for leaks around the oil drain plug and oil filter. If there are leaks, repairs should be made. After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
