Best credit card for fuel under ₹40,000 annual fee

I've been a customer for 6 years. The biggest upside is the customer service. The biggest downside is the slow mobile app. If you do most banking on the app, test the app at a branch before applying — it's surprisingly old.

Honestly, the annual fee is on the higher side. But if you spend consistently on the accelerated categories, the cashback more than offsets it. I did the maths on my own statement last year and came out ahead by about ₹3,200.
