Key Takeaways
- Petrol remains one of the biggest recurring expenses for Singapore drivers, which makes finding the best credit card for petrol genuinely worth the research.
- There is no single best petrol card for everyone—the right petrol credit card depends on your usual station, your spending habits, and whether you prefer cashback or miles.
- The highest savings come from stacking three layers together: the station’s own membership discount, your bank’s card-specific discount, and cashback or miles on top.
- Loyalty programmes such as Shell GO+, Esso Smiles, SPC&U and CaltexGo typically need to be paired with a credit card before the full discount applies. Sinopec’s X Rewards is more straightforward in this regard.
Fuel is a major recurring expense for Singapore drivers, and with elevated pump prices, even small percentage savings add up significantly over a year. Consequently, it’s unsurprising that many drivers, new and experienced, often search for the best credit cards for fuel to optimise their spending.
Maximising petrol savings is highly complex because banks tie benefits to specific stations, credit cards, minimum spends, and fuel grades. A credit card for petrol may offer high discounts at one brand but none at another. Advertised “up to” rates typically require meeting several conditions, including station loyalty memberships and monthly card spend targets.
Confused? This guide compares leading cards across SPC, Sinopec, Shell, Esso, and Caltex to help you find the petrol credit card that matches your driving habits.
How Petrol Transactions Are Categorised (MCC)
Banks use Merchant Category Codes (MCCs) to determine rewards, and petrol purchases usually fall under MCC 5541 (Service Stations) or MCC 5542 (Automated Fuel Dispensers).
Many credit card bonus categories cover both, but always check your card’s T&Cs to be doubly sure. For a deeper look at this fascinating MCC system, see our Merchant Category Code guide.
While we’re at it, electric vehicle (EV) charging is coded differently (often MCC 5552 or 5511) and is rarely covered by most petrol-focused cards. If you drive a hybrid or EV, check our Best Credit Cards for EV Charging in Singapore guide before assuming your current card applies.

UOB cardholders enjoy a total of 15% discount at SPC stacked with the 10% SPC&U card discount. However, these transactions might not earn any UNI$/miles. |
How to Maximise Petrol Savings
Picking a petrol card is a balancing act, not a race to the highest headline percentage discount or rewards-earning prowess.
A card advertising 26% savings at one station is worthless if you rarely fill up there, and many of the biggest “up to” figures only apply once you’ve hit a specific fuel grade, a minimum nett spend, or a quarterly spending target. It’s not the easiest to game the system, really.
The real trick to maximising savings is stacking rather than relying on your card alone. Many maximum advertised savings figures come from stacking several layers:
- The station’s loyalty membership discounts: SPC&U, Esso Smiles, Shell GO+, CaltexGO app or Sinopec’s X Card
- Your bank’s additional card-specific discount
- Any additional cashback or miles earned by your card
Beyond these layers, a few other reward platforms can add an extra layer of value:
- HeyMax sells fuel-adjacent gift cards that can convert an otherwise-excluded petrol spend into a commonly rewarded category, in particular MCC 5311 (Department Stores).
- Sinopec’s X Rewards and Caltex’s CaltexGo app layer a small points-based rebate on top of whatever bank discount you’re already getting.
However, not every layer stacks and maximises savings as well as one would wish. For example, Kris+ at Esso gives Esso Smiles members up to 12% upfront fuel discount (this includes the standard Esso Smiles 10% discount) and 1 KrisPay mile per S$2 of fuel spend (varies according to promo campaigns), but the Kris+ discount applies in place of other existing card discounts at Esso.
By going through the Kris+ route, you get to earn additional KrisPay miles on top of your chosen card’s rewards—at the expense of lower upfront discounts!
Another possible workaround is to buy Shell fuel vouchers through HeyMax. These voucher purchases have been reported to code as MCC 5311 (Department Stores), rather than petrol, which may allow bonus rewards on select cards such as the HSBC Revolution, Maybank XL Rewards, OCBC Rewards, or Citi Rewards Card.
Treat this as a rewards workaround rather than a guaranteed outcome: MCCs and card exclusions are ultimately determined by the merchant and card issuer, so always check your card’s latest T&Cs for confirmation!
Best Credit Cards for Caltex
The best Caltex credit cards include:
| Credit Card | Key Discount | Main T&Cs to Note | Best For |

Linkpoints are redeemed based on gross fuel amount before card promotions or discounts. (Caltex Singapore) | Drivers who want extra savings beyond a Caltex petrol discount |
For Caltex, the strongest options currently include the OCBC 365 Card and Citi Cash Back Card. The OCBC 365 Card offers one of the clearest Caltex credit card discount structures, with up to 22.92% fuel savings when you meet the S$800 monthly spend requirement. Citi Cash Back Card is also very competitive, with Caltex listing up to 23.64% fuel savings.
As a side note, drivers should also use CaltexGO where possible, since the app supports in-app payment, Link Rewards earning, and selected bank-specific Caltex promotion mechanics.
Best Credit Cards for Esso
Sign up for Esso Smiles before comparing cards.
| Best Esso Credit Card / Payment Method | Key Esso Discount | Main T&Cs to Note | Best For |
| DBS Esso Card | Up to 26.2% on Synergy Supreme+ and up to 24.2% on other Synergy fuels | Includes 20%/18% instant discount, S$10 rebate with S$160 nett fuel spend per month, and 1.2% Smiles Point savings | Frequent Esso drivers; likely the best credit card for Esso if you mostly pump at Esso |

The 8% cashback requires Citi Cash Back Card cashback eligibility, subject to the S$800 statement-month spend requirement and Citi Cash Back’s monthly cashback cap |
Drivers who want a flexible cashback card and can make use of the Supreme+ Saturday promotion or the 20.88% savings on other fuel grades |
| OCBC 365 Card | Esso Smiles page lists up to 24.24% savings | Esso’s 24.24% figure comprises a 10% Esso discount, up to 7.04% cashback/rebates, 1.2% Smiles points savings, and 6% rebate on nett fuel spend, provided the cardmember spends at least S$800 on the OCBC 365 Card in a month.

For those with a tendency to refuel at Esso, the DBS Esso credit card remains the strongest station-specific option for regular drivers, especially those who pump Synergy Supreme+ and can meet the S$160 monthly nett fuel spend condition. However, you might be missing out on valuable miles, rewards points or cashback tacked to your credit card(s).
Best Credit Cards for Shell
For ordinary Shell GO+ Drivers, the strongest mainstream Shell credit-card options are currently UOB One Card, with its higher headliner of up to 21.15% fuel savings, and Citi Cash Back Card comes close behind at up to 20.88%.

For Shell, UOB One is still one of the best credit card for fuel options on the market. To maximise any Shell petrol discount, drivers should first register for Shell GO+, then check whether their card discount applies via cashier payment, Shell SmartPay, or physical card presentation to be safe.
Best Credit Cards for Sinopec
Sinopec discounts can be generous, but rates vary by station, membership, app campaign and partner promo. Focus on cards that maximise rewards on top of these promotions.
| Sinopec Discount Option | Key Savings | Main T&Cs to Note | Best For |
| OCBC 365 Card | OCBC states up to 29.5% fuel savings at Sinopec | Enjoy up to a whopping 29.5% fuel savings with an OCBC 365 Credit Card; 25% off fuel at Sinopec for all other OCBC cards, with S$800 monthly spend | Drivers comparing a Sinopec credit card discount with Caltex or Esso |

Sinopec is worth checking if you want a truly simple Sinopec discount without complex bank-card stacking, but the exact Sinopec promotion rate can change by outlet, app campaign or partner scheme. For cardholders, OCBC 365 currently lists up to 29.5% fuel savings at Sinopec, subject to its S$800 monthly spend requirement.
Best Credit Cards for SPC
SPC has an islandwide station network in Singapore, and the SPC petrol discount landscape is led by UOB for drivers who can meet UOB One’s cashback requirements and relatively complicated tiered cashback mechanics.
With SPC&U membership, the UOB One Card currently offers up to 22.66% savings at SPC, ahead of POSB Everyday Card’s up to 20.1% and eligible American Express cards’ up to 21%.
| Best SPC Card / Payment Method | Key SPC Discount | Main T&Cs to Note | Best For |
| UOB One Card + SPC&U | Up to 22.66% savings at SPC | Based on S$60 gross spend: 10% SPC&U, 5% UOB card discount, S$3 off every S$51 nett spend, and up to 3.33% UOB One cashback. Offer valid till 30 Sep 2026 | Drivers looking for the strongest UOB SPC discount |
| Other UOB credit/debit cards + SPC&U | Up to 20% savings | S$3 off every S$51 nett spend requires payment with a physical UOB Mastercard, UnionPay, Visa credit/debit card. No UNI$ for SPC transactions except UOB-issued Amex cards | Existing UOB cardholders searching for UOB SPC or UOB petrol discount |
| POSB Everyday Card + SPC&U | Up to 20.1% savings | Includes 10% SPC&U discount, 5% DBS/POSB card discount and 6% Daily$ rebate on final charge amount | Drivers who want a simpler non-UOB SPC discount |
| American Express Cards + SPC&U | Up to 21% savings | Amex promo applies to eligible Amex-issued Singapore cards and excludes selected corporate/co-branded cards. Valid till 31 Dec 2026. | Drivers who already use an eligible Amex-issued Singapore card |
| SPC+ / e-coupons | Extra coupons may stack with SPC&U and applicable card discounts | SPC FAQ states e-coupons can be utilised alongside SPC&U discounts and applicable credit card discounts/rebates unless otherwise stated; only one e-coupon can be redeemed per receipt. (spc.com.sg) | Drivers watching out for an SPC promotion or SPC promo |
For SPC, the UOB One Card remains one of the strongest options because it combines SPC&U membership, the UOB SPC discount, the S$3 off every S$51 nett spend mechanic, and UOB One cashback. This makes it a strong contender for the best petrol card if you can meet UOB One’s monthly spend and transaction requirements.
However, SPC transactions generally do not earn UNI$, except for payments made with UOB-issued American Express cards, so miles chasers should not assume every UOB petrol discount will be tacked onto additional credit card rewards points. POSB Everyday and eligible American Express cards are good alternatives for drivers who want a simpler SPC petrol discount without relying on the relatively complex UOB One cashback terms and conditions.
Conclusion
The best petrol card depends on your preferred station and reward preference. Stack station loyalty memberships with bank discounts and card rebates to maximise value. Tools like Kris+ and HeyMax can provide extra benefits if you use them right. For more on reward optimisation, see our HeyMax Guide.
