What is the original oil specification for Toyota IZOA?
2 Answers
The original oil specifications for Toyota IZOA are 0W-16, 0W-20, 5W-20, 5W-30, 10W-30, or 15W-40 engine oil. Any oil model that meets these specifications can be used. For later maintenance and oil changes, you can choose brands such as Mobil, Shell, Castrol, or Total. The viscosity of the 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. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high temperatures. The method for changing the oil in Toyota IZOA is as follows: Wait for the engine temperature to drop and allow the oil to flow back into the oil pan; Loosen the oil drain plug with a wrench and use 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; Remove the oil filter with a special wrench; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the 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 oil leaks around the drain plug and oil filter. If there are any leaks, perform repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
I've been driving a Toyota IZOA for a while now, always using the manufacturer-recommended 0W-20 full synthetic oil. I learned this from the user manual, and the 4S shop technician repeatedly emphasized the benefits of this oil: it saves fuel, protects the engine from wear, and is especially suitable for frequent start-stop driving in urban SUVs like the IZOA. I once tried using oil with a different viscosity, like 5W-30, and the fuel consumption increased noticeably. I switched back to 0W-20, and everything returned to normal. I change the oil every 10,000 kilometers or 6 months to keep the car in optimal condition. If you're buying oil yourself, I recommend choosing products with ILSAC GF-6 certification. Mobil or Shell's 0W-20 is also very reliable—don't be tempted by cheap, low-quality oil.
