Why is my 2020 RAV4 getting worse MPG than EPA ratings?
Your 2020 Toyota RAV4 should hit 27 MPG city, 35 MPG highway, or 30 MPG combined per EPA ratings. Many owners in areas like 75023 see 22-25 MPG instead. Common causes include low tire pressure, aggressive driving, and skipped maintenance. Fix these to gain 2-4 MPG fast.
