What is the oil specification for Toyota Corolla?
2 Answers
The suitable oil specification for Corolla is 5W20, while older Corolla models can opt for 5W30 oil which has one grade higher viscosity than 5W20, providing better engine protection. For post-maintenance oil changes, brands like Mobil, Shell, Castrol, and Total can be considered. Oil viscosity changes with temperature variations, so special attention should be paid to its performance under both low and high temperatures. Taking 5W-30 as an example, the first number indicates low-temperature fluidity - 5W means it can withstand -30°C, with smaller numbers representing better cold-flow properties for smoother cold starts. The latter number represents kinematic viscosity at 100°C, where higher values indicate better viscosity retention and lubrication performance under high temperatures. The oil change procedure for Corolla is as follows: Wait for the engine temperature to drop, allowing oil to fully drain back to the oil pan; Loosen the drain plug with a wrench and collect old oil in a container until completely drained. Start the engine for 30 seconds to flush remaining oil from main galleries; Remove the oil filter using a special wrench; Apply oil to the new filter's gasket and hand-tighten it clockwise; Add new oil through the valve cover filler port, typically filling three-quarters of a standard oil container; Run the engine for 5 minutes and check for leaks around the drain plug and filter; After stopping the engine, use the dipstick to verify oil level falls within standard range.
I've been driving a Toyota Corolla for almost ten years. The owner's manual recommends using either 5W-30 or 0W-20 engine oil, depending on the model year and engine. Mine is a 2012 Corolla, and I've always used 5W-30 full synthetic oil, which ensures quick starts in winter and reliable lubrication without overheating concerns in summer. For every oil change, I insist on going to reputable shops and choosing premium brands like Castrol or Mobil certified products. Using the wrong oil grade can increase engine wear, affecting fuel efficiency and longevity. Oil change intervals are crucial; full synthetic oil only needs to be changed every 8,000-10,000 kilometers—no need for excessive frequency to avoid wasting money. Ambient temperature affects the choice: 0W series is recommended for cold northern regions for easier starts. Maintaining the Corolla's engine oil is simple; as long as you follow the manual, you won't go wrong, and the car will run smoothly and reliably. Choosing the right grade and sticking to regular changes can significantly reduce the risk of malfunctions.
