MBB Ikhwan Visa gives you 8% cashback, but the limitations make it very difficult to actually get the cashback. You need to reload at Petronas on Saturday or Sunday. The problem is, there is only one Petronas that accept CC in KL/Selangor, which is the Puchong-Sg Besi Bypass Petronas near Sunway LDP toll. So unless you happen to live near there, or work during weekend and pass by there, then it's not worth the hassle. You'll probably end up spending more money than the cashback just to drive there.

I have Ikhwan Visa, but I just stick to my Ikhwan MasterCard and get 5% cashback.

I see, so cannot reload on Sunday then... Have to do it on Saturday with amex card

I tried but some are already close can't use CC anymore, so was thinking and melakas and johorian to update those place together
