My Suzuki Liana 2009 lxi is giving very poor fuel mileage. It gives me around 7-8km/L in city and around 11km/L on highways. It's driven less than 45000 kms and totally on Petrol. I got its spark plugs, air filter, oil filter, engine oil, gear oil, tuning coolant and brake pads changed and throttle body and brake discs and drums serviced recently from Suzuki Central Motors but I'm still getting poor fuel mileage. I usually don't drive fast.
My friend told me to get its injectors cleaned. I plan to do it myself as I have already spent much. So anyone who knows where are injectors located in Liana please let me know.
And please tell me if there could be anything else that I might have missed that could be causing this issue.
