What grade of engine oil is used in the Toyota RAV4?

Toyota RAV4's original engine oil model is 5W-40, and the brand is Toyota. If you want to change the oil during later maintenance, you can choose brands such as Mobil or Castrol. 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—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. 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 under high temperatures, which can also be understood as providing better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Toyota RAV4 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 oil drain plug and place an oil pan underneath to collect the old oil until no more oil flows out. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain. Use a specialized wrench to remove the oil filter. Apply some new oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add the new engine oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a standard oil container. Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made. After stopping the engine, pull out the oil dipstick to check if the oil level is within the standard range.
As a Toyota RAV4 owner for several years, I directly referred to the user manual when encountering this issue, which clearly recommends 0W-20 synthetic oil. I use the full synthetic type because it has good fluidity, preventing engine stiffness during cold starts in winter and reducing the risk of overheating in summer, thereby helping to improve fuel efficiency. I typically change the oil every 6,000 to 8,000 kilometers, depending on driving habits—earlier if I frequently drive long distances. Remember not to use oil grades arbitrarily; higher grades like 5W-30 may be cheaper but are not suitable for the RAV4's engine design, potentially leading to increased fuel consumption or wear. Before changing the oil yourself, always check the dipstick to ensure the oil level is adequate but does not exceed the maximum mark, ensuring safe and worry-free driving.
I've worked in the automotive repair industry for many years and have serviced numerous Toyota RAV4s. The common oil specification is 0W-20 full synthetic oil. Its low viscosity ensures smoother engine lubrication, reduces friction loss, and extends engine life. I recommend owners stick to this specification and avoid experimenting with unusual grades, as the RAV4's engine is optimized for this specification. Oil change intervals should be maintained between 7,500 to 10,000 kilometers, depending on city or highway driving. Overused oil turns black and affects performance. Additionally, the oil brand isn't as important as the API certification—choose SN or SP grade oils. Regularly check the dashboard warning lights while driving; address issues early to prevent them from becoming major problems.
