What is the oil specification for the Leiling?

5w-30 is the oil specification used by the Toyota Leiling. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, or Total. The viscosity of the 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 for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher this number, the better the oil maintains its viscosity index at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Toyota Leiling is 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 no more oil flows out. Start the engine and let it run for about 30 seconds to allow the oil in the main oil passage to drain out; Use a special wrench to remove the oil filter; Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the oil filler cap on the engine's valve cover, typically filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any oil 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 check that the engine oil level is within the standard range.
I've been driving the Leiling Hybrid for several years, and the engine oil specification is particularly important. It usually recommends using 0W-20 full synthetic oil, especially for newer models after 2018. Why? Because this oil has low viscosity, starts up super fast in winter, and ensures smooth oil flow without clogging; it also cools and protects the engine in high summer temperatures, reducing wear and extending the car's lifespan. I strictly change it every 8,000 kilometers or six months, and I've found that fuel consumption can be controlled at around 6L, which is much more economical than regular 5W-30. Remember, don’t skimp on cheap oil, or the engine noise will increase and it may be prone to malfunctions. By the way, there might be slight variations for different model years—my manual states to prioritize Toyota-certified 0W-20. Checking the spark plug condition during maintenance also helps with overall upkeep.
