We have a 2006 CV Rav (2.4ltr 4cyl) and got 435km out of the tank until the light come one. Apparently when the light comes on you have on average about 8ltrs left ? Given that, we would have achieved approx 10.30ish litres per 100km. That was a mix of city, highway, inbetween (80km speed limits) and a bit of bush track driving and beach. Pretty good performance all round really
