What kind of engine oil does Toyota use?
1 Answers
Toyota's dedicated original engine oil is Toyota Genuine Oil. The specific oil models for Toyota include 0W20, 5W20, 5W30, 5W40, and 10W30. 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, where 5W represents the ability to withstand -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 this number, the better the oil can maintain its viscosity index under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing Toyota's engine oil is as follows: Wait for the engine temperature to drop, which also allows the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place 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 oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the oil filler cap on the engine valve cover, usually 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 and check that the engine oil level is within the standard range.
