Hello, For a comparison my 2007 Camry which should be identical enginewise averages 10-11/100km in city/suburban driving so same conditions as you. I use 91ULP only. Car was averaging 13.5L/100km when i first got it. If this is high milage car, see if spark plugs been swapped recently, should be 90,000 service - this will also effect milage. Recommended tyre pressure for camry on the manufacturers placard is just way too low so could be a factor - ofcourse there is your driving style, correct tyre pressure, fuel used and how many people/items you carry to keep in mind.
