Well, I have been reading many reviews among which many reviews are such in which people have been writing about mileage issues. Mostly people who face problems write reviews here, which is not fair because I believe people who are enjoying and having problem free services should also write.
Hyundai i10 era (1.1Liter engine, IRDE2), I have purchased it in the month of September 2011 and till date I have covered 24500 Kms, I have done regular service at regular service intervals.
I always keep in mind to do wheel balancing and wheel alignment after every 5000 Kms. Till now, I did not require to change any spare.
I get amazing mileage from the first day, I get mileage of 14.5 Kmpl within city with a/c always switched on and on highways 23-24 Kmpl with always a/c switched on. Hyundai services always rock.
