Cheapest Petrol in Singapore After Discount

Here is the honest version most price lists skip. The pump price for RON 95 or 98 sits within a few cents across every brand, so chasing the lowest advertised number rarely saves you real money. What actually moves your bill is the discount you get at the counter.
For most people the biggest instant wins are simple. If you drive for a platform like Grab, Gojek or Lalamove, your driver rate is worth 22 to 32 percent off, more than any card. If you do not, the right app or card at Caltex, Sinopec or Esso gets you a clean 16 to 23 percent straight off the pump, no minimum spend and no waiting for cashback.
This page ranks the best instant discount you can get at each brand. The deeper 20 to 30 percent totals you see advertised usually stack a monthly minimum spend on top, and those live in the card guide.

Want the deeper 20 to 30 percent?
The headline totals banks advertise usually stack a cashback or rebate on top of the instant rate, and that part needs a monthly minimum spend. For example DBS Esso adds 5 percent with a minimum of about $160 a month, and Citi Cash Back adds 8 percent at Shell, Esso and Caltex with a minimum of about $800 a month. See the full picture, condition by condition, in the card guide.
Instant discounts are the app or loyalty rate taken straight off the pump price, with no minimum spend. Note the Esso to Aster rebrand from 1 July 2026, and that Sinopec rates vary by outlet. Verified Jul 2026, terms change, so confirm on the provider's own page before you fill up.
Frequently asked questions
What is the cheapest petrol in Singapore after discount?
It depends who you are. A Grab, Gojek or Lalamove driver gets the lowest effective price, roughly 22 to 32 percent off, using their platform rate at Caltex, Esso or Sinopec. For a normal driver with no minimum spend, Sinopec with an OCBC card (up to 23 percent) or Caltex and Esso at 18 percent give the best instant price.
Is it worth switching brands just for a bigger discount?
Only if the station is convenient. The pump price gap between brands is a few cents, so a bigger percentage discount at a station near you almost always beats a smaller one across the island. Do not burn petrol driving to a cheaper pump.
Do instant discounts need a minimum spend?
No. The rates on this page are instant and upfront, taken off the pump price at the counter or in the app with no minimum spend. The deals that need a monthly minimum, like DBS Esso plus 5 percent or Citi Cash Back plus 8 percent, are cashback or rebate on top, and you can see those in the card guide.
How do the driver discounts work?
Platforms like Grab, Gojek and Lalamove partner with fuel brands to give registered drivers a special rate. Caltex via CaltexGO gives Grab drivers 26 percent and up to 32 percent, Esso gives Gojek drivers 23 percent, and Sinopec gives Lalamove drivers 28 percent. You need to be signed up as a driver to use these.
Why are pump prices so close between brands?
Fuel duty and wholesale costs are broadly the same for everyone, so brands compete on discounts rather than the list price. That is why the sticker price barely moves but the after-discount price you pay can differ a lot.
