What is the oil specification for Toyota Corolla?
1 Answers
0W-20, 5W-20, and 5W-30 are the oil specifications adopted by Toyota Corolla. As long as the oil meets these three specifications, it can be used. In addition to the original oil, Corolla can also choose oil brands such as Shell, Mobil, and Castrol. The viscosity of the oil will change 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, resulting in smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it maintains viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Toyota Corolla 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 drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover filler port, typically filling about three-quarters of a bottle; Start the engine and let it run for 5 minutes, checking for oil leaks around the drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick to ensure the oil level is within the standard range.
