I have made the tunning for Prius 1.8 2010 (throttle body cleanning and plugs,engine oil,air filter,oil filter change). The fuel average has become low after this.I have used 0w20 engine oil TOTAL.Can anyone tell why this low average is happening?

Islamabad.Mileage 90000Didn't have anything cleaned or changed wrt catalytic converter and fuel pump.
first of all , do use it little bit more and then see millage, it may set as ECU takes a bit of time in setting itself...
but i wont recommend 0w20, coz meter is reversed for these cars, you must use 5w 30 ur 10w 40,
