About fuel on this motorway

Petrol and diesel along the M40

The M40 runs london to birmingham. Along the 18 junctions we track you'll find both on-motorway service areas (MSAs) that you can only reach from the road itself, and off-junction forecourts within 2 miles of a slip road.

How we group stations

Each junction lists every forecourt within 2 miles of the slip road, sorted by price. Motorway service areas appear inline on the junction they sit between. Toggle the direction of travel to filter down to just the carriageway you're on.

Is it cheaper to fill up off the motorway?

Right now the average motorway service area on the M40 charges 204.9p/L, versus 180.8p/L at nearby off-junction stations — a services premium of 24.1p/L. A 55-litre fill would cost about £13.24 more at the services.

How up-to-date are these prices?

Prices are refreshed from government open data every 15 minutes. The most recent update per station is shown next to each row.

Frequently asked questions

Q.How many fuel stations are along the M40?
We track 49 stations across 18 junctions — including on-motorway service areas and nearby off-junction forecourts within 2 miles of a slip road.
Q.Are motorway service areas more expensive than off-junction stations?
Usually, yes. On the M40 the average services premium is currently 24.1p/L over nearby off-junction stations. Prices vary day-to-day, so use the direction toggle and fuel selector above to compare the exact prices at each MSA against off-junction stations you can reach from the same junction.
Q.Where does the fuel price data come from?
Retailers publish prices under the government's Fuel Finder scheme. We refresh from those feeds roughly every 15 minutes and show the last-updated time on each station row.
Q.Can I get to any of these forecourts without leaving the M40?
Only the stations tagged "Motorway services" are directly on the M40. Everything else requires exiting at the junction listed on the row — the distance shown is the road distance from the slip road.
