mesra card is loyalty card. register online to check points earned, locations, etc

petronas gift card is a prepaid card with $$ credit inside.

same here. lucky draw even more sux. in-store purchases at rm1 or something and lubricant discount.

it's a gamble lor, cuz we dont know which card PDB going to send, the black or the green.

put in GC, select language, 2 options [Enter Amount] or [Fill Up]. Choose [Enter Amount] and use the keypad below to enter amount.

[Fill Up] is when you want to pump full tank without knowing the exact amount to pump. it will stop after tank is full.

for your example, definitely will stop. I usually select this option when balance rm10-20.

another reason to stop: capped rm80 per pump. just reinsert again to pump the balance.

flat RM10 discount or 10% max RM10?

oo that's good
