What is the oil specification for the Corolla 1.2T?
2 Answers
Toyota officially recommends using genuine Toyota Pure Performance oil for the Corolla 1.2T: 0W-20 full synthetic oil. In addition to the genuine oil, you can also choose brands such as Shell, Mobil, and Castrol. However, you must use oil with the following specifications: 0W-20, 5W-20, 5W-30, and 10W-30. The Corolla 1.2T requires approximately 4 liters of oil for an oil change, though usually less than 4 liters. Relevant information is as follows: Note: If SAE 10W-30 or higher viscosity engine oil is used in cold weather, the engine may be difficult to start. Therefore, it is recommended to use SAE 0W-20, 5W-20, or 5W-30 engine oil. Symbol meanings: The 0W in 0W-20 indicates the oil's cold-start performance. Using oil with a lower number before the W makes it easier to start the engine in cold weather. The 20 in 0W-20 represents the oil's viscosity characteristics at high temperatures. High-viscosity oil (with a higher value) may be more suitable for high-speed driving or heavily loaded vehicles.
I've been using 0W-20 full synthetic oil for my Corolla 1.2T engine for several years, and it's been quite hassle-free. This low-viscosity oil ensures quick cold starts in winter and maintains proper thickness even in high summer temperatures, providing excellent engine lubrication protection. I change it every six months or after driving 8,000 km. At the service center, they recommend oil brands that meet Toyota standards, such as Idemitsu or Mobil – never use cheap alternatives as they may damage the turbocharger. Choosing the wrong oil can lead to increased fuel consumption, louder engine noise, and in severe cases, shortened engine lifespan, making regular maintenance crucial.
