The Singapore Fuel Price Update September 2025 has brought fresh adjustments to petrol and diesel rates. For car owners and businesses, fuel costs remain one of the most closely watched expenses.
This month, fuel prices have seen notable revisions, influenced by global oil markets, regional supply chains, and domestic policy adjustments. For motorists, the latest update means recalculating travel budgets, while transport companies must reassess operating costs.
Petrol Prices in September 2025
The latest update saw petrol prices climb slightly, reflecting higher global crude oil benchmarks.
-
92-Octane Petrol: Averaging S$2.90 per litre, this option remains the most affordable for everyday drivers.
-
95-Octane Petrol: Prices stand around S$3.05 per litre, making it the most widely used grade among private car owners.
-
98-Octane Petrol: Premium petrol climbed to about S$3.50 per litre, catering mainly to high-performance cars.
The increases, though modest compared to earlier spikes, are still adding to household expenses for regular drivers.
Diesel Prices in September 2025
Diesel, the backbone fuel for commercial vehicles and buses, also saw an upward revision.
-
Auto Diesel: Averaging S$2.65 per litre, slightly higher than August.
-
Euro 5 Diesel: Priced at S$2.70 per litre, reflecting cleaner emissions standards.
The rise in diesel prices directly impacts logistics, delivery, and public transportation sectors. Companies relying on large fleets face higher operating costs, which may be passed on to consumers in the form of delivery charges or service fees.
Why Fuel Prices Changed This Month
Several factors contributed to the September 2025 revision:
-
Global Crude Oil Prices: Brent crude crossed the US$95 per barrel mark, pushing up fuel costs globally.
-
Regional Supply Chains: Refinery maintenance in Asia tightened supply, influencing imports.
-
Currency Exchange Rates: A weaker Singapore dollar added to the cost of importing fuel.
-
Carbon Tax Adjustments: Government policies on emissions have also influenced pump rates.
This combination created upward pressure across both petrol and diesel categories.
Impact on Motorists
For private car owners, the Singapore Fuel Price Update September 2025 means higher monthly driving expenses. A family driving a 1.6L sedan could spend S$30–40 more per month compared to earlier in the year.
Drivers are now looking at cost-saving strategies such as:
-
Refueling during discount hours at petrol stations.
-
Using credit card tie-ups for rebates.
-
Driving less and relying more on public transport for daily commutes.
Impact on Businesses
Businesses that rely on logistics, delivery, and transport services are particularly affected. Courier companies and ride-hailing operators have already flagged higher costs.
Small businesses running delivery fleets must now either absorb the increase or adjust customer fees. Meanwhile, larger logistics companies are negotiating bulk fuel purchase deals to reduce exposure.
Government and Market Response
The government continues to monitor fuel trends closely. While no direct subsidies for fuel are expected, measures such as expanding EV adoption and encouraging public transport usage are being emphasized.
Petrol companies are also offering loyalty programs and cashback schemes to soften the impact on motorists. However, these promotions are limited and do not fully offset the rising costs.
Long-Term Trends
Fuel prices in Singapore remain tied to international oil markets, meaning volatility will continue. Analysts predict that unless crude oil drops significantly, prices are likely to stay at elevated levels for the rest of 2025.
This reality is accelerating the push toward electric vehicles (EVs), with many Singaporeans considering the switch to avoid unpredictable petrol costs. The latest COE and EV incentives further reinforce this trend.
Conclusion
The Singapore Fuel Price Update September 2025 brings yet another reminder of how global markets affect everyday costs. Both petrol and diesel saw moderate increases, impacting households and businesses alike.
While careful planning and rebates can ease the burden, the long-term solution appears to be a shift toward cleaner and more cost-stable alternatives such as EVs. For now, Singaporeans will need to adjust budgets and keep a close eye on future updates.
