Latest Fuel Prices Today September 2026: Pertamina Dex and Dexlite Surge, Pertamax Holds Steady

After two consecutive months of decline, fuel prices in Indonesia reversed course in the September 1, 2026 adjustment. This time the increase landed on non-subsidized diesel, the single largest cost component for many operational fleets.

Pertamina Dex climbed Rp4,050 to Rp25,200 and Dexlite rose Rp4,000 to Rp23,700, the steepest increases recorded so far in 2026. Pertamax Turbo (RON 98) also went up by Rp1,300 to Rp19,600. Meanwhile, regular Pertamax (RON 92) and Pertamax Green 95 held steady at Rp15,950 and Rp16,600 respectively, as did the subsidized fuels Pertalite and Biosolar. For diesel fleet managers, this means a significant jump in monthly costs literally overnight.

Below is the latest Pertamina fuel price table for the DKI Jakarta (Greater Jakarta) region in 2026, showing the change from the August 2026 period.

*Prices apply to regions with a 5% PBBKB rate such as DKI Jakarta. The September 1, 2026 adjustment covers only Pertamax Turbo, Dexlite, and Pertamina Dex; Pertamax, Pertamax Green 95, and subsidized fuels still reflect previous adjustments.

Fuel prices rise and fall in step with global oil prices and the rupiah exchange rate. The adjustment mechanism is governed by Ministerial Decree ESDM No. 245.K/MG.01/MEM.M/2022, which sets the base-price formula for general gasoline and diesel products.

According to Kitty Andhora, VP Corporate Communication at Pertamina Patra Niaga, this round of adjustments was deliberately limited to a handful of non-subsidized products. Pertamax 92 and Pertamax Green 95 were held at their existing prices, a decision made with economics, consumer purchasing power, and broader social conditions in mind. In practice, the increase was concentrated on premium and diesel products rather than the gasoline most retail consumers rely on.

This article compares fuel prices from Pertamina, Vivo, BP, and Shell for those who depend on fuel for company operations. Knowing where each operator stands makes it easier to identify the cheapest gasoline, the highest-octane option, and how diesel prices compare.

Non-Subsidized Diesel Price Movement

Diesel Prices Are Volatile, So How Much More Will Your Fleet Spend This Month?

A Rp4,000 per-liter increase looks small on the pump display, but it turns into a serious number once multiplied across a fleet's consumption. For a 20-vehicle fleet burning 9,750 liters per month, the Dexlite increase alone adds Rp39 million per month, or nearly Rp468 million per year, without a single extra kilometer driven. In a situation like this, the only variable a fleet can still control is how efficiently each liter actually gets used.

Assumptions: a fleet of 20 units, 150 km/day, 26 operating days, fuel economy of 8 km/liter (9,750 liters per month), Dexlite at Rp23,700.

Fleet Diesel Cost Simulation at Current Prices

September's diesel increase looks dramatic on paper, but its real impact on monthly operating costs only shows up once you run the numbers at fleet scale. Here are two simulations based on the prices currently in effect.

Simulation by Diesel Type

Assumptions: 20 units, 150 km/day, 26 operating days, 8 km/liter. Total monthly distance: 78,000 km, diesel needed 9,750 liters/month.

*Monthly fuel cost simulation for a 20-unit fleet based on September 2026 diesel prices.
*Biosolar is listed for price comparison only, not as an operational recommendation. Company operational vehicles generally don't meet the criteria for subsidized fuel.

Simulation by Vehicle Type

Assumptions: 150 km/day, 26 operating days (3,900 km per month per unit).

*Biosolar is listed for price comparison only, not as an operational recommendation. Company operational vehicles generally don't meet the criteria for subsidized fuel.

Full-Tank Cost at Current Pertamax Prices

Here are estimated full-tank costs based on the Pertamax price of Rp15,950 per liter in the Greater Jakarta and Java regions. Because Pertamax was left unchanged in the September adjustment, these estimates are the same as last month. Several of the vehicles listed below are also commonly used as company operational vehicles.

How Fuel Price Changes Affect Company Operating Costs

Fuel price changes hit hardest in industries that run vehicle fleets as part of daily operations, such as:

Last-mile delivery using motorcycles or vans

Companies providing operational vehicles for sales teams with high mobility

Car rental businesses

Field service providers (AC servicing, internet installation and repair, home cleaning, and the like)

Food and beverage businesses handling delivery orders

So what do these fuel price changes actually mean for those businesses? Here's a breakdown.

1. Ballooning Fleet Costs

Company vehicles, from executive cars to sales vehicles to delivery vans and trucks, absorb a heavy share of fuel spending. Take a single light truck consuming around 488 liters a month: its diesel bill climbs from Rp9,613,600 in August to Rp11,565,600 in September. That extra Rp2 million applies to just one unit, with no additional distance driven at all. The figure grows sharply once multiplied by the number of working days and the number of vehicles running each day.

2. Rising Allowance and Reimbursement Costs

Costs also climb if your company provides transportation allowances or fuel reimbursement. On the other hand, if the company chooses not to raise allowances or decides to cap reimbursements, that can dent the productivity and morale of your field team.

3. Sharp Changes in Logistics Vendor Rates

Even if your company doesn't run a logistics fleet, the impact still reaches you if you rely on third-party delivery services. When fuel prices shift, logistics providers are very likely to apply a fuel surcharge, so your company ends up feeling it anyway.

4. Higher Procurement Costs

Another effect shows up in procurement. Vendors such as raw-material suppliers, office-supply providers, and maintenance services may raise their prices, so your company risks spending more than in previous months.

5. Shrinking Profit Margins

The next consequence is the dilemma a company faces as operating costs climb: either accept a thinner profit margin or raise selling prices, which carries the risk of losing customers.

Frequently Asked Questions About Fuel Prices (FAQ)

How much is 1 liter of Pertamax?

One liter of Pertamax (RON 92) in the Greater Jakarta area costs Rp15,950 as of September 2026, unchanged from the August price. In provinces with higher PBBKB rates such as West Sumatra and Riau, Pertamax can reach Rp16,650 per liter.

Why did diesel prices rise in September 2026?

The September 1, 2026 increase in non-subsidized diesel was the steepest adjustment of the year so far. Dexlite rose Rp4,000 to Rp23,700 per liter and Pertamina Dex rose Rp4,050 to Rp25,200 per liter. Pertamina stated the adjustment follows the government-set formula, weighing global crude prices, the rupiah exchange rate, taxes, and consumer purchasing power. The adjustment was deliberately limited to selected products, which is why Pertamax 92 and Pertamax Green 95 were held steady. For companies running diesel fleets, this increase feeds directly into monthly operating costs.

What is the price of fuel today?

As of today (September 2026), Pertamina fuel prices in the Greater Jakarta area are: Pertalite Rp10,000/liter, Pertamax Rp15,950/liter, Pertamax Green 95 Rp16,600/liter, Pertamax Turbo Rp19,600/liter, Biosolar Rp6,800/liter, Dexlite Rp23,700/liter, and Pertamina Dex Rp25,200/liter. Non-subsidized fuel prices are adjusted by Pertamina on the 1st of each month and can vary by province depending on the local PBBKB rate.

Did fuel prices go up in September 2026?

Yes, but only partially. In the September 1, 2026 adjustment, three non-subsidized fuels went up: Pertamina Dex rose Rp4,050 (to Rp25,200), Dexlite rose Rp4,000 (to Rp23,700), and Pertamax Turbo rose Rp1,300 (to Rp19,600). Regular Pertamax and Pertamax Green 95 were left unchanged at Rp15,950 and Rp16,600 per liter. Subsidized fuels such as Pertalite and Biosolar also stayed the same.

Did Pertalite go up?

No. Pertalite (RON 90) remains Rp10,000 per liter, unchanged in both the August and September 2026 adjustments. As a subsidized fuel, its price is set by the government and tends to stay stable, unlike non-subsidized fuels such as Pertamax Turbo and Dexlite that are reviewed periodically in line with global oil prices. The government, through the Energy and Mineral Resources Minister, has also confirmed that subsidized fuels such as Pertalite and Biosolar won't rise through the end of 2026, giving households and businesses cost certainty.

What percentage did Pertamax gasoline go up?

Pertamax (RON 92) did jump around 32% on June 10, 2026, from Rp12,300 to Rp16,250 per liter. It then fell Rp300 to Rp15,950 on August 1, 2026, a decline of about 1.85%. In the September 1, 2026 adjustment, Pertamax was left unchanged and remains Rp15,950 per liter in the Greater Jakarta area. September's increases landed instead on Pertamax Turbo, Dexlite, and Pertamina Dex.

How can you save on fuel when prices rise?

1. Keep tire pressure at the recommended level for more efficient consumption
2. Avoid sudden acceleration and hold a steady speed
3. Cut excess load in the vehicle
4. Service the engine and change the air filter regularly
5. Plan routes to steer clear of traffic

For fleet managers, fuel waste often goes unnoticed. Inefficient routes, excessive idle time, and fuel misuse can add to operating costs every month. GPS tracking and fleet management systems help monitor fuel consumption in real time, so the savings are actually measurable.

Why do non-subsidized fuel prices change every month?

Non-subsidized fuels like the Pertamax Series and Dexlite are reviewed periodically under the mechanism set out in Ministerial Decree ESDM No. 245.K/MG.01/MEM.M/2022. The two main drivers are movements in global oil prices and the rupiah's exchange rate against the US dollar. When global oil eases, non-subsidized prices tend to correct downward, and they rise when oil strengthens. That's why adjustments are usually announced on the 1st of each month, with amounts that can differ by province depending on the local PBBKB rate. For fleet managers, this monthly swing makes fuel costs hard to predict if you're relying on manual reports alone, which is exactly why real-time consumption monitoring matters for keeping the budget under control.
