Krishna and allhyundaicars, Krishna was correct about me. I had an accent crdi when i joined and the username still remains the same. Bought the verna 1.6 vtvt this august.
I will clean my air filter and AC filter once in two weeks or at least once in a month. There will be some insect or dried leaf blocking the air flow in both. Also tapping it gently against the floor and a gentle blow from inside out will clear the loose dust deposit. It will be easy to clean it when there is no rain and if we perioidically do this, the air filter will stay almost in its stock bright white colour.
If it rains or somehow if the paper becomes moist, then the dust accumulated will stick to the surface and wont go even if we clean with air jet. The colour of the filter paper also will turn to pale brown due to the dust deposited and got fixed due to the moisture.
Try this out and this helps me so far
Regarding the FE, the MID figure will vary between 16- 17.2 when i stay in the top gear for considerable time. Immediately after the refill, it will go crazy and even touch 28 but for a very short span. As the FE stats gets reset when we fill more than 6 litres, it requires some constant monitoring to arrive at a stable figure.
But always i have seen at least one km drop in the actual FE when compared to whats shown in the MID. By tankful to tankful method, i get 15-16 on an average and it keeps improving gradually as the car clocks more kms in the odo.
