EU diesel price API: why you shouldn't pay $750 a year for public data

Where EU diesel prices actually come from

Every week, the European Commission publishes the Oil Bulletin — a dataset covering diesel, petrol, and LPG prices for all EU member states, plus a handful of neighbouring countries. It has been running continuously for over 20 years. The data is free, public, and downloadable directly from the EU's official website.

The Oil Bulletin collects prices from national energy authorities across the EU. It covers both the pump price consumers pay and the pre-tax price, which is what matters most for transport operators trying to understand the actual cost of fuel across different countries.

This is the foundation of almost every EU diesel price dataset you will encounter. Any company selling you "EU diesel price data" is, in the vast majority of cases, working from this same source.

So why do people charge $750 for it?

There is a real answer to this, and it is worth taking seriously rather than dismissing it entirely.

The Oil Bulletin is a raw file. It requires parsing, cleaning, normalising across different country formats, and loading into a database before it becomes useful in an API. Someone has to do that work, maintain it week after week, handle the occasional data errors in the source file, and keep the API running reliably. That has a cost.

Some providers also add value on top of the raw data:

• Faster publication — the Oil Bulletin sometimes lags by a few days, and some providers source prices more directly from national markets
• Broader country coverage — including non-EU countries not in the Oil Bulletin
• Price forecasts — forward-looking estimates based on crude oil futures and market analysis
• Corrections — the Oil Bulletin occasionally publishes errors, and some providers catch and fix these before they reach customers

These are legitimate additions. But $750 a year for weekly EU-27 prices with no history included? That is hard to justify when the underlying data is free and the EU publishes 20+ years of history in the same download.

What transport operators actually need

Most transport companies and freight forwarders need diesel prices for one of three things:

• Fuel cost calculation — estimating the fuel cost component of a route based on current prices in each country the truck passes through
• Fuel surcharge triggers — contracts often include a fuel surcharge clause that activates or adjusts when diesel crosses a certain price threshold
• TMS and ERP integration — feeding current prices into internal systems so that cost calculations stay current without manual updates

For all three of these, weekly EU-27 prices with a reasonable history are sufficient. You do not need daily prices or proprietary forecasts for standard transport costing. The Oil Bulletin data, properly structured and delivered via API, covers the need.

Diesel prices are rising — and that makes accurate data more important

The volatility of diesel prices over the past few years has changed how transport operators think about fuel costs. When prices were stable, a rough estimate was good enough. When prices swing by 20–30% in a year, the difference between an accurate fuel cost and a rough one can be the difference between a profitable contract and a loss-making one.

This is why more companies are looking to integrate fuel price data directly into their costing tools rather than relying on a planner to manually check and update a spreadsheet. The manual approach works when prices are predictable. It breaks down when they are not.

What a fair price looks like

We built our diesel price API on the same EU Oil Bulletin data, processed weekly, covering all EU-27 countries plus additional European markets. It includes the full historical series — the same 20+ years that the EU publishes — not just the current week.

We are not charging $750 a year for this. The API is available as part of a RouteCalc subscription, which starts at a fraction of that price and includes the full route calculation platform alongside the fuel data.

If you need diesel prices for a TMS integration, a fuel surcharge model, or just to stop updating a spreadsheet manually every week — that is exactly what the API is for.
