Castrol announced on May 20, 2026, that former UFC champion and WWE star Ronda Rousey will serve as the new brand ambassador for Castrol EDGE Extended Performance Premium Synthetic Motor Oil. The partnership unites the global lubricants leader with one of combat sports’ most recognized athletes.
Rousey appears in a new commercial and across digital, social media, and retail channels as part of the campaign. The announcement came just days after Rousey secured a victory in competition this past Saturday.
“I’ve built my career on never backing down and always pushing to be the best,” Rousey said in a statement. “I see that same fighting spirit in Castrol. They are relentless in their pursuit of performance, and I’m excited to join the team and help showcase what it means to demonstrate ultimate performance.”

Partnership Built on Performance Values
Fabiana Neves, CEO of Castrol Americas, said the company chose Rousey for her alignment with brand values. “Ronda represents the discipline, resilience and relentless pursuit of excellence that we engineer into every Castrol EDGE product,” Neves stated.
The campaign draws parallels between Rousey’s training regimen and the demands placed on modern car engines. Both require endurance, strength, and performance under pressure, according to Castrol’s messaging.
Castrol EDGE Extended Performance is a premium full synthetic motor oil designed for engines that are smaller and more powerful than previous generations. The product addresses the increased stress these modern engines face during operation.
Seven Areas of Engine Protection
The marketing push highlights Castrol EDGE Extended Performance’s ability to perform in seven critical areas. These include pressure, power, fuel economy, high-temperature performance, cleanliness, wear protection, and endurance.
Castrol claims the product provides the highest level of wear protection and thermal stability compared to industry standards. The motor oil is engineered to handle severe operating conditions while offering extended drain intervals.
Rousey’s crossover appeal from mixed martial arts and professional wrestling helps Castrol reach younger car owners through social media and short-form video content. The campaign targets performance-minded consumers who prioritize long-lasting engine protection.
Castrol is part of the bp group and serves automotive, marine, industrial, and energy sectors worldwide. The company has more than 125 years of history developing lubricants, coolants, and greases for various applications on land, air, sea, and space.
Rousey joins Castrol’s roster of brand representatives known for their competitive spirit and commitment to excellence. Her focus on preparation and refusal to accept mediocrity mirrors the standards Castrol applies to product development.
The campaign is now live across multiple platforms, including television commercials, social media channels like Instagram and Facebook, and in-store retail activations.
