Using 5W20 instead of 0W20 for your RAV4 is possible, but not recommended for long-term use. The number before the 'W' refers to the oil's viscosity at cold temperatures, meaning 5W20 is slightly thicker when cold. Toyota specifies 0W20 for optimized fuel efficiency and engine protection, especially in cold weather. If 0W20 is unavailable, 5W20 can be a temporary substitute, but it's best to switch back to the recommended viscosity at your next oil change for optimal vehicle performance.
