Fuel prices are set to rise again. This is how much drivers may pay from 1 September

Norway's Parliament decided in the spring to temporarily reduce taxes on petrol and diesel. The reason was a rapid increase in fuel prices following the start of the US and Israeli war with Iran on 28 February. The reduction was in effect from 1 May to 1 September 2026. Data analysed by Nettavisen indicate that stations largely passed the tax relief on to prices at the pumps, although fuel was more expensive in July and August than in June.

From 1 September, charges will increase again. For diesel, the <span class="highlight id_79673">tax</span> will rise from NOK 3.86 to NOK 8.38 per litre after VAT is included. This means a difference of NOK 4.52. For petrol, the charge will rise from NOK 4.75 to NOK 9.46, with the difference including VAT amounting to around NOK 5.60 per litre.<br /><br />In recent weeks, Nettavisen has regularly recorded prices at stations in the Oslo area. At the end of August, peak diesel prices ranged from NOK 24 to NOK 26 per litre, while petrol cost just over NOK 22. After the reinstated charges are added, diesel may cost approximately NOK 28.50 to NOK 30.50 per litre at such times. In the case of petrol, the price may reach around NOK 26.60.

Data from the Drivstoffappen app show clear regional differences. In August, the average petrol price nationwide was NOK 19.45 per litre, which would be around NOK 25.05 after adding the returning charge. Northern Norway was the most expensive, with an average of NOK 20.52. The lowest figure was recorded in the eastern part of the country, where the average was NOK 19 per litre.<br /><br />The situation is similar for diesel. The national average was NOK 21.57 per litre, while after taking higher taxes into account it would be around NOK 26.09. In the north, the average reached NOK 22.70, while in Eastern Norway it was NOK 21.19. Drivstoffappen also indicated that, on the same day, the difference between the cheapest and most expensive diesel in the country was nearly NOK 8 per litre.

However, prices are influenced by more than just taxes. In recent weeks, Brent crude contracts have cost between USD 78 and USD 94, while oil had previously reached USD 115 per barrel. Analysts also point to higher holiday demand, limited diesel exports through the Strait of Hormuz, and lower global stocks of this fuel. An additional factor remains the risk associated with attacks on Russian refineries, which may increase demand for fuel from other suppliers.
