No. Castrol is owned by BP, the British multinational oil and gas company, not by Honda.
To understand the question, it helps to know that Castrol is a long-standing lubricant brand that operates under BP. Honda, meanwhile, is a vehicle manufacturer that may specify Castrol lubricants for maintenance in some markets, but it does not own the Castrol brand.
Who owns Castrol?
Castrol is a brand and business unit owned by BP plc. BP acquired Castrol in the early 2000s and has operated Castrol as its global lubricants brand across automotive, industrial, and marine sectors ever since.
Here are the essential facts about Castrol's ownership and its relationship with Honda:
- Castrol originated as Castrol Limited, a British lubricant company founded in 1899 by Charles W. Castrol.
- BP acquired Castrol in 2000, integrating it into BP's global lubricant operations.
- Today Castrol functions as BP's flagship brand for automotive, industrial, and marine lubricants worldwide.
- Honda Motor Co. does not own Castrol; Castrol is not part of Honda's corporate ownership structure.
- In some markets, Honda may specify Castrol lubricants in service programs or approved maintenance, but this reflects supplier relationships, not ownership.
Conclusion: Castrol remains a BP-owned brand, and Honda is not its owner.
Castrol and Honda: what is their relationship?
Honda and Castrol interact primarily through supply and recommendation channels. While Honda may endorse or approve certain Castrol products for use in its vehicles or service centers, ownership rests with BP, not Honda. Consumers should follow the vehicle’s manual and the dealership’s guidance when selecting lubricants.
Practical takeaway for drivers
Always check the owner's manual for the recommended oil specification (viscosity and grade). If Castrol lubricants meet those specifications and are available in your region, they are a valid option within the brand’s BP ownership framework.
Summary
Castrol is owned by BP, not Honda. Honda may direct the use of Castrol lubricants in certain markets, but ownership remains with BP. The relationship is best understood as a supplier/recommendation dynamic rather than a corporate ownership one.
