Maybe not one credit card. But combination of mbb2card and citibank cash back plat should do it. Mbb2card only weekends... Then weekdays you can use citibank. Please take note of t&c of the cards.

Also maybank visa signature but you didnt mention your income but the two above should do it for 1k.

Or only mbb2card but you can only pump during weekends and not all petrol station accepts amex

HLB wise is also a good choice but you need to fulfill the terms and condition to make 10x RM50 transaction before you can enjoy the 10% rebate.
The HLB wise rebate RM 100 max
citibank shell rebate too little and only lock on to shell station.
UOB one card got quota, once monthly quota hit, then no more rebate

eh, i forgot wise card cause i always thought the requirements are annoying. but 1k is a huge a mount. you can simply swipe 10 times > RM50 every month.

Note citibank shell is restrictive. you need to spend on other things as well. effective rate of cash back is actually not that high.

so you can consider
1) wise card
2) maybe a 2nd like mbb2card or citibank cash back plat.

edit: i didn't recommend uob one because since not too long ago, uob one has this pool limit on petrol cash back. alot of forum-mers complaining in uob thread not getting cashback. so, it's NOT GUARANTEED cash back anymore.

the True about Citi-Shell Card, You Won't any CB Below RM300 on Petrol Spend...
