Kavitha, I'll give you a slightly different take here because I think the co-branded fuel card route is overrated for someone in your situation.
Here's the thing — co-branded cards lock you to one fuel company. What happens when that particular pump is closed, or you're travelling and only find an HP pump? You lose the benefit entirely. I've seen friends stuck like this.
Instead, consider the **HDFC Millennia Credit Card** or **Axis Bank ACE Credit Card**. ACE in particular gives 2% cashback on everything including fuel via Google Pay. It's not 4% like a co-branded card but it works at ANY pump, any city, any time. Axis Bank ACE is honestly underrated — ₹499 annual fee, waived on ₹2 lakh annual spend which is easily doable.
Also the **SBI Cashback Card** gives 5% on online spends and 1% everywhere offline including petrol. Cashback posts monthly, not quarterly.
The one thing I disagree with people saying about co-branded cards — the 'fuel points' system sounds great on paper but you need to track redemption deadlines, minimums, and sometimes the pump staff themselves don't know how to process it. I've stood at a pump for 20 minutes while the guy tried to figure out point redemption on a busy evening. Not worth the stress.
My pick for you: Axis ACE card. Simple, flat cashback, no fuel company dependency, works on Visa everywhere.
