So 2 months back I got this car. It’s a Tata tigor petrol xm variant. So the ideal plan was to get a compact and fuel efficient car as I already own 2 more cars(hector & Triber). We had an alto , exchanged it for this one.
Did so much research on this car , on an avg this should at least give 15kmpl even with worse driving conditions. But look at this. 9.7kmpl.
First service is completed. What’s going wrong with it?
Yes there is traffic as I’m from Kolkata. But still keeping everything in mind this shouldn’t be giving such low mileage. Even my other cars give around the same.
Advices and Suggestions would be appreciated. Thank you
