1st mileage is awesome 18 per ltr.. is great.. mine is 5k driven and Alhamdulillah m happy to get 16.5 at same speeds as urs without ac, however with ac at position 2,3 it gave me 14.5 kpl
In second case, tyre pressure doesnot seem to be an issue at 40 psi there should be more average technically because of less friction, that seems to be a fuel issue and think thats also because of local driving.
