Well, my Camry (3SFE, 2L) does just under 600km of mostly highway driving, on a tank of approx 55L. It does about 500-550ish km of city driving on the same tank. Towing a trailer, I got less than 300km on the same tank. Mostly because I had to rev each gear out a fair bit, and even doing 90km on the highway I had to sit in 4th gear, unless I was going downhill. On the steeper hills it was back to 3rd...
My Corolla (4AGE), I have no idea because I've never run the tank much below 1/4...
