How much engine oil should be added to the Teana 2.5?

[EzraDella]

The official manual of the Teana recommends engine oil models 5W-30SN and 0W-40SN. For the Teana 2.5 model, 4.5 liters of engine oil is sufficient. Any oil model that meets these two specification parameters can be used. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, and Castrol. 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, and the smoother the cold start of the car will be. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it can maintain viscosity 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 Teana is as follows: Wait for the engine temperature to drop, and also allow the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug, and use an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply engine 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. Generally, fill about three-quarters of a bottle; Start the engine and let it run for 5 minutes, then check for oil leaks around the oil drain plug and oil filter. If there are any leaks, they should be repaired; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
