ok a few updates on my side about my wagon R 2012 model. I bought it back in October 2015.
it was 16.5K mileage at that time. Till now i have driven it around 6.6k+ .. Mostly in-city Lahore . One out of city trip to Gujar Khan (near pindi) with whole family + luggage aboard .
In city , its giving me between 19.5 to 21.5 km/litre . I calculate almost on every tank full . I mostly use mixture of Hi-octane + super petrol by ration 50:50 .
on that out of city trip . it gave me 21 km/litre . this was with full load 5 people + luggage. we went on GT road ( not motor way)
I changed oil with LiquiMoli 0w20 , and imported oil filter from filter house. I dont know if its really imported but its quite good quality compared to guard or lipon filters available in market.
air filter still original (from japan) is working well even after 6.5k and in lahore pollution . and the guy at filter house tell it will easily go 2-4k more .
Over all .. I am extremely happy and satisfied with this car. Its like i am driving a luxury. no noise, so comfortable. its a joy to drive. Ma sha Allah and Alhamdulillah
