My friend's 5 months old santro gives 10Kmpl in Bangalore traffic, figo's mileage of 12-13kmpl in city sounds good to me, with kerb weight of 1040+KG. We are compromising 1-2kmpl when compared with other hatchbacks with 1.2ltr engine but for which we are getting little extra space, on face when we drive and that to for lesser price. Figo is fun to drive on Highways with fun-tastic handling .
Congratulations! Nice color you have opted there. We’re waiting for an ownership thread along with some pictures. Welcome to community, and enjoy your stay.
Your monthly usage is very low so petrol is advisable. If you monthly usage is more than 1000 KMS then diesel is good.
You go for petrol as whatever higher premium you will pay for diesel the amount of petrol used for that difference you will be able to cover it in many years so that is a big saving for you.
FIGO petrol will give you around 12 after first service and will also depend on how you drive it.
You will get 9-10 KPM initially with new car and dont panic.
