Kizashi Club

My Kizashi is already completed 60,000 Km nothing was wrong with the car.

When the dealer replaces the sparks on 60,000 km service her I start notice that the fuel consumption increase! Before full tank will cover 480 km inside the city but now only 390 km distance then the fuel light turns on!

I tried to fill fuel from different petrol station but I got same result.

If anyone experiences such a thing please advice.

Your fuel consumption may have been reset recently so it's showing as if the car's using more fuel and still learning your current driving style and calculating average consumption. Give it few days to settle then see if it goes back to normal.

Otherwise if the reset isn't the case, take it to the dealer to see if there are any codes stored on your OBDII. Maybe some sensors are faulty (unlikely tho, but worth checking out).

Is your increase noted based upon the car's heads up display, or, based upon kilometers driven divided quantity of fuel pumped in to your tank at refill?
