[Resolved]  Maruti Suzuki — Mileage problem with swift dzire

I am Sanjay Desai - M.no.[protected] email id:[protected]@yahoo.com

Dear Sir
from last 6 months I am facing mileage problem in my car I received mileage 11 kmpl
I have all petrol bill eith marking of kilometer from last 6 months
actual mileage certify by Maruti Suzuki is 19 kmpl we knew in city we are not able to get this average
I take two different test drive from two Maruti service centre.their was vast diff. among two dealer
# first I received 16.9 kmpl mileage at car speed 25 kmhr we drive 17 kilometer with 11 trafic signal
sir I also drive daily for my office for 34 kilometer with average same speed with mileage 11 kmpl
I also twice drive on highway straight 200 kilometer then also my mileage was not go up but still 11 kmpl
# second test we received 22.3 kmpl mileage at car speed 45 to 50 kmhr we drive 33 kilometer
both time dealer put some SDT Meter in car - any manipulation can be done with help of this meter?
Maruti Suzuki certify Mileage is 19 kmpl
I received milelage below 11 kmpl
one test drive shown 16.9 kmpl
second drive shown 22.3 kmpl = how it is possible? how car can give more mileage(22.3) then certify mileage(19.)
we thank to god now petrol price come down otherwise it is very difficult
Maruti is not ready to solve this problem -and not accept any problrm in engiene they give me standard answer that we are not sure about mileage
it depend on traffic and road condition. we belived this but from last 6 months no change in mileage
my humble request to you please look in to this matter and try to resolved as earlier as possible
Regards
Sanjay Desai
