The engine oil for a 2011 Toyota RAV4 with a V6 engine is 5W- 30, while the 4- cylinder model needs either 5W- 20 or 10W- 20 engine oil, as recommended by Toyota. Engine oil should be changed on a regular basis, as part of regular maintenance and to prevent engine damage.
RAV4 owners should follow Toyota's guidelines for oil changes to help extend the life of their vehicle. The engine oil and filter should be replaced every 5,000 miles, or 10,000 miles if synthetic oil is used, according to the Toyota website. Owners should also replace the engine oil and filter at every 15,000 miles and every 30,000 miles.
