I have Honda Accord cl7 2003 Model, i bought it back in March, the issue i am facing is fuel consumption, when i bought the car, it was with 235/75R17' tyres, it gave me 300KM in full tank(60L) if i roam in local city while if i travel on long route, it give me not more then 550-600KM/tank. I changed the tyres to 195/65R15'(Genuine size) i changed the plugs to irridium tech, got it reprogrammed, did everything i could to increase fuel average. But all in vain, still 300 KM/tank. What else could be done? How could i increase average?
A guy suggested me to look for injectors, which colour fuel injectors are genuinely installed in it? Any idea?
