I bought in 2010. Im getting great mileage on highways and local roads, I used to get less mileage and I understand what was the problem. the tyre pressure was the problem. if you are going for a long drive, just fill up the air 34 on all tyres and start you will get good mileage.
Im following this formula and with maintaining speeds within above 80 km/h getting 25 kmpl. dont be shocked just try it and you will get it . nice to other all
