What Type of Engine Oil Does the RAV4 Use?
2 Answers
Toyota RAV4's original factory engine oil brand is Toyota Genuine Oil. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, or Total. The official Toyota RAV4 manual recommends oil models of 0W-20, 5W-20, 5W-30, and 5W-40. Any oil model that meets these four specifications can be used. The viscosity of engine oil changes with temperature, so special attention must 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 temperatures as low as -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 viscosity better at high temperatures, which can also be understood as better lubrication performance under high temperatures. The method for changing the engine oil in a Toyota RAV4 is as follows: Wait for the engine temperature to cool down, and also allow the oil to flow back into the oil pan. Use a wrench to loosen the drain plug and place an oil pan underneath 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. Use a special wrench to remove the oil filter. Apply oil to the seal of the new oil filter and tighten it clockwise by hand. Add new oil through the engine valve cover filler port. Generally, fill about three-quarters of a bottle. Start the engine and let it run for 5 minutes. Check for leaks around the drain plug and oil filter. If there are leaks, perform necessary repairs. After stopping the engine, pull out the dipstick and check that the engine oil level is within the standard range.
As a long-term RAV4 owner who has performed maintenance multiple times, the manual recommends 0W-20 full synthetic oil. This low-viscosity oil flows quickly at low temperatures, protecting the engine during cold starts and reducing wear. I've used both Mobil 1 and Toyota's original brand with good results. From an environmental perspective, 0W-20 oil improves fuel efficiency, saves gasoline, and reduces emissions, making it much greener than traditional high-viscosity oils. I change it every 5,000 miles to ensure the engine remains efficient and free of carbon buildup, which also helps extend the vehicle's lifespan. There are many brands on the market now, but choosing one with API certification gives more peace of mind. Remember not to switch to other viscosities randomly to avoid damaging the sealing system and increasing repair costs.
