Unhappy Mileage Problem (Accent CRDi) after Scheduled Diesel Engine Purge!

My Accent CRDi's was scheduled serviced at 58000 kms from Hyundai Service Center. I get my services done at regular 8000 kms intervals. Besides regular parts changed such as diesel filter / oil filter / air filter / engine oil etc. I got de-carbonizing with Wynns diesel engine purger.

After the service/purge was done, i clocked 2000 kms more and I found some problem with the mileage, which has drastically dropped to 8-10 kmpl on Highways. This bothered me a lot and I took my car to service center, where they cleaned the fuel injectors and catalytic convertor at 60000 kms. Since my car was not emitting any black smoke before and after the service is done.

Now at 63000 kms done the problem remains the same. Mileage!

Please guide some solutions!

Thankyou!
