I bought Honda N One Non Turbo version, the guy I had bought it from had messed up the car. However, a few things did improve the cars overall performance and i still want it more.
Initially changed the air filter with oil based air filter it improved the intake as well the mileage too. Spark plugs all new oil filter all new, throttle body work were additional work done to get good average. I commute between Faisalabad and Lahore including driving in the both cities. Th car gives healthy 18 - 20 km/l with on and off AC requirement, I drove this car to Muzaffrabad, Peer Chensai and Neelum valley it gave me average of 18.1km/l. Last time I went back to FSD the average I had was 21km/l I used ZOOM Hi Octane that comes recommended for Audi, other than that I use PSO High Octane.
Please note that I drive the car very light feet in city and as well as intercity travelling. However, on my way back to Lahore, I observed very unusual behavior of the car, the eco light on the techo meter would not turn green with the speed of 100km/h and eco mode on. The engine sounded louder than usual, and it consumed more fuel than usual in a one sided trip with 17km/l average. I pulled over checked if the something with air filter is wrong but it was fine.
In this case I cannot figure what other possibilities can be assessed to address this matter. Your guideline / help would be required???
