I have been using citibank indian oil credit card since 1 year and it is working for me so far. This is a visa card which best works for those who uses a lot of fuel.
The rates and charges average and it will cost Rs 1000/Year( waived off, if spend Rs 30, 000) in an year. There is no joining fees for this card but approval from citibank can be tricky!
You will earn 4 point for ever Rs 150 spent if you spend on indian oil petrol pump( check citi bank website for authorized pumps) . For rest of the spending you will get 1 point for Rs 150 spent. Reedemption is like, Rs 1 of free fuel for 1 point or Rs 0.30 for every point otherwise.
Serivice and support is pretty ok, citibank representatives will give you ans for your queries pretty quickly and satisfactorily. There is no problem at this end.
I am satisfied after using this card, but opt for this if your monthly fuel bill is more than Rs 5000 and you have an indian oil pump nearby( check citibank website for authorize pumps) .
