Nine people have been arrested in Surrey after damaging fuel pumps and gluing themselves to forecourts at service stations on the M25.
Images shared online showed protesters with Just Stop Oil banners at Clacket Lane services, Kent; Cobham services, Surrey; and Thurrock services, Essex.
The climate group said 32 of its supporters blocked access to petrol pumps by sitting in the road with banners at around 5am.
Some also sabotaged petrol pumps by breaking display glass and covering them with spray paint.
Surrey Police said they were "working as quickly as we can to remove the protesters from the service stations".
There is currently no petrol available at either station due to the disruption, including on both sides of Clacket Lane.
The arrests were made on suspicion of criminal damage.
"We appreciate the disruption this is causing and we are working as quickly as we can to remove the protesters from the service stations," Surrey police said.
In an update, the force added: "Officers remain at the scene and a total of nine people have been arrested on suspicion of criminal damage."
Posting a statement on Twitter, the environmental group said: "Four service stations on the M25 have been blocked. Oil will continue to be disrupted until there is a meaningful statement from Downing Street."
Sophie Sharples, a 22-year-old student from Brighton, who is taking part in the Just Stop Oil blockades, claimed ending fossil fuel consumption is this generation's "mission".
She went on: "We have such a short window of time to act to avoid the complete destruction of all we know and love.
"For all life, and for the love of humanity, I have to do everything I can, and with my privilege I am able to face arrest, so I will."
On Tuesday, Just Stop Oil also blocked two oil depots in Essex and Warwickshire, resulting in 35 arrests.
The group warned it will "continue the disruption until the Government makes a statement that it will end new oil and gas projects in the UK".
