Hi all My punto emotion 1.3 has clocked 7500kms within 4 months...and iam interested in engine oil and air filter change.What made my mind do it is because of the comparatively low mileage the car is delivering right of only 15.5kmpl according to MID.My run is around 85% in high ways maintaining a speed for around 40-70 in sedate driving conditions.The tyre pressure is maintained regularly. After driving my friends punto 1.3 (done with 4500kms)i felt that its more refined,smooth and quiet. 1)What can be the reason for low mileage figures??Replacement of engine oil and air filter will it lead to better mileage figures?? 2)Should i stick on with selenia 5w40 for the next 7500 kms?? 3)i understood from the posts that there are other better engine oil available in the market.Which engine oil will u suggest??Should i go for it nw??or at service during 15000kms?? 4)If i should change the air filter or is there any provisions to clean it and insert back??
