Climate group Just Stop Oil said 51 of its supporters are disrupting seven petrol stations across central London.
In some locations, activists rendered fuel pumps unusable by breaking their display glass or covering them with spray paint.
At others they blocked access by sitting on the road with banners. The action started at 6am.

The group has repeatedly protested against oil use in recent days, including at service stations on the M25 motorway.
The Metropolitan Police said it made five arrests after an incident at a petrol station in west London.
A spokesman said: “Police were called at 6.29am on Friday to reports of protesters damaging pumps at a petrol station in Talgarth Road, Hammersmith.
“Officered attended and within approximately 10 minutes had arrested four men and one woman on suspicion of criminal damage.
“They remain in custody at a west London police station. Inquiries are ongoing.”
One of the activists, Tez Burns, 34, said: “I can’t live with myself, knowing what I know, without doing all I can to stop new oil and gas.
“We are suffering the worst cost-of-living crisis in 40 years and facing climate breakdown because of our dependence on oil.
“Yet the government is allowing energy companies to drive us into poverty with skyrocketing energy bills, and is failing to protect us from the consequences of climate collapse. Enough is enough.
“We are not special, we are ordinary people, with different backgrounds and stories to tell, who have overcome the fear of causing disruption.
“We know from history that nonviolent civil resistance works. Will you also step up and join us, or will you look back in 10 years wishing that you had?”
While Jade Calland, 29 added: “I cannot stand by while young people, people on low incomes and those least responsible for the climate crisis have their lives destroyed.
“Today we are resisting the government’s plans to allow more oil and gas. We want to stop the misery forced on millions by rising energy bills, food poverty, poorly insulated housing and a society run for the benefit of the fossil fuel companies and the rich.
“In October, thousands of us will occupy Westminster until the government agrees to end new oil and gas.
“Don’t be a bystander, step up and join us. Now is the time to resist the destruction of everything we love."
