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