Ok, I'll try to do the best I can converting it (since we go my miles and gallons here). I have the same 70L fuel tank, and have a '96 TRD Supercharged V6 Camry. I was doing a REALLY long drive 3 weeks ago. A little bit at the beginning, I was haing fun with some friends, so I was doing some 0-130kph runs. About 1/3 the tank was about 95kph (non-cruise control), 1/2 the tank was probably around 110kph (with cruise control). When I finally filled up with like 6-8L left, I had averaged 28mpg. When factoring in the rest the tank at that mileage, it was 518 miles (833km) for the entire tank.
