On the banks’ own figures as at November 2026, the best petrol credit card in Singapore saves between about 20% and 24% off the pump price, depending on the station. The Citi Cash Back Card and OCBC 365 Credit Card post the highest stated totals, and both need S$800 of monthly spend.
Most of that saving is not from the card. It is the station’s discount and loyalty programme, stacked with a smaller card discount and cashback. This article separates the layers, using only what each bank’s page states.
How We Compared Petrol Cards
We kept cards whose issuer publishes a fuel saving and, where possible, its breakdown. We compared:
- the cashback rate on petrol and what it is calculated on;
- the upfront discounts the bank says stack with it, and at which stations;
- the minimum monthly spend, cap, annual fee and minimum income.
We excluded offers with an end date and sign-up gifts. Fuel discounts are agreements between banks and oil companies and are revised often, so confirm at the bank’s page or the station before relying on any figure.
How the Discounts Stack: A Worked Example
Take an illustrative driver who buys $300 of petrol a month at pump prices and uses the Citi Cash Back Card at Shell. Citi’s petrol page gives the layers.
- Shell GO+ discount, 10%: $30 off.
- Citi card discount, 4%: $12 off. The driver pays $258.
- Citi Cash Back, 8% on the net amount: 8% of $258 is $20.64.
Total saving: $62.64, which is 20.88% of $300. That matches the figure Citi states for Shell.
Over a year, that is about $752. But split it by who provides it:
- $360 comes from Shell GO+, which does not depend on this card;
- $144 is the instant Citi card discount;
- about $248 is cashback, paid only in months when total card spend reaches $800, and counted within the card’s $80 monthly cap.
So the card-specific value is about $392 a year. Citi lists an annual fee of $196.20. If it is paid, the card adds about $196 a year for this driver.
The short version: A “20% fuel saving” is mostly the station’s discount. At $300 of petrol a month, the card itself adds roughly $30 a month, and the cashback part needs you to hit the card’s minimum spend first.
Petrol Credit Cards Compared
Figures are from each bank’s own page, as at November 2026.
| Card | Issuer | Petrol cashback | Stated total saving | Minimum monthly spend | Cap | Annual fee | Minimum income |
|---|---|---|---|---|---|---|---|
| Citi Cash Back | Citibank | 8% at any service station | Up to 23.64% Caltex; 20.88% Shell | $800 | $80 a month in total | $196.20; first year waived | $30,000 |
| OCBC 365 | OCBC | 6% at any service station | Up to 22.1% Caltex; 20.2% Esso; 24% Sinopec | $800 | $160 a month across 6% categories | $196.20; first two years waived | $30,000 |
| UOB One | UOB | Up to 5% at Shell | Up to 21.15% Shell | $2,000 for the full rate | Additional cashback capped at $120 a statement month | $196.20; first year waived | $30,000 |

What Each Card Pays, and the Catch
Citi Cash Back Card
Citi pays 8% on MCCs 5541 and 5542 (service stations and automated fuel dispensers) anywhere, above $800 of spend in the statement month. Its petrol page states:
- Caltex: a 17% station discount plus 8% cash back, up to 23.64%. For most Citi cards the 17% applies to Techron fuel paid through the CaltexGO app.
- Shell: 10% Shell GO+ plus 4% Citi discount plus 8% cash back, 20.88%. The physical card and a valid Shell GO+ membership must be presented.
- Esso: a 5% site discount, 5% Esso Smiles discount and 4% Citi discount, then 8% cash back. Citi’s higher Esso headline includes a Saturday-only discount on one fuel grade.
The catch: the $80 cap covers dining, groceries and rides too. It does not suit drivers whose total card spend is below $800.
OCBC 365 Credit Card
OCBC’s terms from 1 November 2026 pay 6% on MCCs 5541 and 5542, with an $800 minimum and a $160 cap shared with dining, groceries and land transport. Its page states up to 22.1% at Caltex (18% upfront plus cashback), up to 20.2% at Esso (16% upfront plus cashback) and up to 24% at Sinopec (20% upfront plus cashback).
The catch: the fuel-savings section of the page works out its totals using 5% cashback on the net amount, while the cashback terms state 6%. Check which is current. Fleet card top-ups do not count. It does not suit low spenders.
UOB One Card
UOB states up to 21.15% at Shell: 10% Shell GO+, a 7% UOB One instant discount, and up to 5% cashback. The 5% is the card’s 3.33% quarterly cashback plus an additional 1.67% on Shell that applies only at the $2,000 monthly spend tier.
The catch: quarterly cashback needs the same spend tier and 10 purchases in every month of the quarter. UOB also lists an SPC offer, but it carries an end date, so we have not counted it. It does not suit drivers with uneven monthly spending.
HSBC Live+ Credit Card
HSBC states “up to 17% upfront fuel savings and additional 5% cashback at Caltex and Shell” in Singapore. The 5% sits within the card’s $250 quarterly cap, and the card needs $600 of eligible spend a month.
The catch: the page does not break the 17% into station and card portions. HSBC’s income bar is $65,000 for new customers. It does not suit drivers who use other brands. See our HSBC Live+ Card review.
POSB Everyday Card
POSB lists 6% cash rebates on fuel at SPC with no minimum spend, paid as Daily$. A footnote refers to the net amount after a 5% card discount and a further 10% with the SPC&U card.
The catch: the page does not state a combined saving or validity, and directs readers to the card terms. Other stations earn 0.3%. It does not suit drivers who do not fill up at SPC.
Also stated by an issuer
Trust Bank’s page says the Trust Link Credit Card gives “up to 20%” fuel savings at Caltex, without a breakdown. We could not verify the layers, so it is not in the table.
When a Petrol Card Does Not Add Much
- You drive little. At $150 of petrol a month, the card-specific saving is about $15.
- You cannot reach the minimum spend without buying things you do not need.
- You are loyal to a brand the card has no tie-up with. You would get the cashback only.
- You carry a balance. UOB charges 27.8% a year on unpaid balances, and MoneySense notes late fees are often a flat $100. Interest on one unpaid $800 month is about $19, close to a full month of fuel cashback.
What To Do Next
- Note which station you actually use and join its free loyalty programme first. That discount is yours with any card.
- Check your total monthly card spend against the card’s minimum.
- Confirm the current discount on the bank’s page; fuel offers and promotions change.
- See how a petrol card fits with the rest in our guide to cashback cards and the credit cards overview, or read the bank pages for Citibank, OCBC and UOB. To weigh rebates against miles, use the cashback vs miles calculator.
