Wrong fuel on the M40
Misfuelled on the M40? We cover the whole route, north west from Denham through Buckinghamshire, Oxfordshire and Warwickshire to the M42 near Birmingham, 24 hours a day.
Broken down on the carriageway? Hazards on, leave by the nearside door, get behind the barrier. In a live lane or in danger, call 999 first. Never let anyone work on a car on the hard shoulder.

FAQs
M40 misfuel questions
I've put the wrong fuel in at M40 services. What now?+
Leave the engine off. Put the car in neutral and, with staff help, push it clear of the pump. Tell the cashier, then call us. We drain cars on motorway forecourts and in services car parks every day.
My car cut out on the M40 after filling up.+
Get everyone out by the nearside door and behind the barrier. If you're in a live lane or feel in danger, call 999. Then call us — we'll arrange for the car to be moved somewhere safe before draining it.
Can I drive to the next junction?+
Please don't. Running the engine on the wrong fuel is what causes expensive damage, and breaking down in a live lane is dangerous.
