Corolla average going down need help

[maaz.jutt.10]

I have a 2019 corolla altis 1.6 it’s average decreased up to 8.0 and is still decreasing. Need to know reason why is it doing this?

[mashriqain]

1. What was the average before? During winter and last summer if you had the car then?
2. What is your Oil change/Air Filter change routine?

[sfjsag]

Well seems like a new car and i believe its average will improve with driving.
Other than that, yes, you should have clean filters and oil with appropriately inflated and stock size tyres.

Reset trip meter.
And it will increase with time. But will never go beyond 10kmpl. 10kmpl is max for altis 1.6

1.6 fuel avg shall be 12+ / litre in city & 14+ over highway run
do not believe the cluster display of fuel consumption use 3 tank top up method to ascertain real average.
