Hello all:
I bought a Wagon R VXR about 6 weeks ago. The fuel economy is 10-11 km/l which I think is very poor.
We keep the RPM low and don't take the car beyond 80-90 km/h. My reborn with similar driving habits gives me slightly better mileage on similar roads (mostly in DHA, Lahore).
I took the car to Suzuki Cantt motors for 100km inspection and reported the issue. The mechanic told me to compute the mileage by refueling only after one day of drive (~80km) and the results would be better 
I told the mechanic that I barely get 350km on full tank and that is how the mileage is calculated but he did not believe me, I think. I insisted on running the OBD scanner and check the spark plugs. The mechanic reported all good (not sure if I should trust him after listening to his method of calculating mileage!)
I see many other people complaining about poor mileage on Wagon R in 10-12 range. But many others are getting 15+ as well. Any mechanic I should take the car to? Can I report it to Suzuki somehow? Any other advice? Thanks for your time.
