The company that evolved into Castrol was founded in London in 1899.

The company has finalized a $6 billion deal to sell a majority stake in its lubricants business Castrol to a US investment firm.

Details of the Major Deal

The energy major sold a 65 percent share in Castrol, which makes oils for automobiles, bikes, and commercial machinery, to New York-based Stonepeak.

This transaction valued Castrol at $10.1 billion, with BP obtaining $6 billion cash, which it will allocate to reducing debts and enable it to focus on its primary operations.

BP will hold onto a 35 percent share in Castrol, which it originally acquired in the year 2000.

A Strategic Pivot and Asset Sales

The London-based oil major stated the sale represents a "key moment" in its plans to overhaul its business and strip out expenses.

BP in February revealed intentions to divest $20 billion worth of assets in a bid to prioritize its primary fossil fuel operations and strengthen its financial position.

After this latest agreement and earlier disclosures, the company states it is more than halfway to meeting that goal.

It is also shifting its strategy away from investment in renewable power and refocusing on its focus on oil and gas following calls by some investors who were disappointed that its profits and share price had lagged behind competitors.

Sector Context and Executive Updates

Rivals such as Shell and Norway's Equinor have also scaled back plans to invest in green energy.

The Castrol sale arrives a week after BP announced its first female chief executive, Meg O'Neill, who will assume leadership in April 2026.

Her surprise appointment came only three months after BP named a new board chair, Albert Manifold.

And she was handed the top job less than two years after Murray Auchincloss succeeded Bernard Looney as CEO.

Ongoing Business Streamlining

This recent transaction is the latest in a series of divestments by the company, which included selling its US onshore wind energy business and its Dutch mobility and convenience arm.

Acting CEO Carol Howle said the sale represents a "excellent result for all stakeholders".

"We are simplifying our structure, concentrating our refining and marketing on our leading integrated businesses, and accelerating delivery of our strategy," she stated.
