Why would you say something is wrong? This is great. I have read other testimonials on this gas mileage...lemme see if I can find them.
Here is what I do, and have been doing since I was told by a fellow TOYOTA dealership mechanic supervisor when i bought the Runner. At fill-up, I reset my odometer. When I fill-up, my tank is 3/4's empty(I never run it empty passed that). I have 1/4 tank left (so my needle reads) and my odometer always reads 290-300. Here in Florida, stations are all self-service. I stick the nozzle in my tank and wait for it to shut off automatically. Once it does, I always manage to pump a good $4-$5 more of fuel, without it overflowing ( i have mastered the method of listening to the sound of when fuel is near the top). Please note*** this isn't good practice for any other car and is not an exception with the Runners. Thing is, the way our fuel neck is curved, the pump senses full, when indeed it is not. So you have that allowance to put 2-3 gallons more of fuel without messing up you fuel system (ie: carbon canister etc.) I think that is why I am able to get a good 100 miles per mark (full, 3/4, 1/2,1/4, empty) TRY IT OUT!!!!! Works for me.
