Are there any performance plug option for aspire which may improve the fuel efficiency and performance?
My car is giving me 10.5 now with light foot on the accelerator and with Air Conditioning switched on for 70% of the drive. I checked the Air Filter is was quite bad so I went to Honda to get it changed. They refused giving the same excuse of not changing anything before 5000KMs. Instead they manually removed the dust and asked me to drive again till 5k. My current mileage is around 3600KM.
Is it a justified act?
