Hi Zhang Junhuang, thank you for your question.

The $1.89 SPC Diesel price listed on our Fuel Discounted Price page is inclusive of a 29% discount, combining two components:

1. An instant 24% discount when you use the UOB One card at SPC petrol stations.

2. An additional 5% promotional discount specifically for UOB One Card users.

This combination of discounts brings the total savings to 29%, resulting in the stated price of $1.89.

If you have any further questions, feel free to use the Chat feature in the Motorist app. Thank you.
