Sime Named Millers Oils Brand Ambassador for 2025: A Perfect Union of Performance and Heritage

Millers Oils is proud to announce Barry Sime as one of our team of Brand Ambassadors for 2025, solidifying a partnership built on years of mutual passion, performance, and engineering excellence. Barry’s lifelong connection with motorsport — and especially his dedication to the iconic Mini Cooper S — makes him the ideal face for our ongoing MINI Campaign, which celebrates the innovation and spirit of one of Britain’s most beloved classics and how Millers Oils has a solution for EVERY MINI.

A Legacy of Motorsport

Barry Sime has been synonymous with speed and precision from his early karting victories to his competitive stints in Formula Ford and Formula Renault. However, it’s his commitment to historic touring car racing — and in particular, the Morris Mini Cooper S — that truly sets him apart. Barry campaigns a highly competitive 1275cc Mini Cooper S in prestigious events such as the Goodwood Revival, Silverstone Classic, and HSCC Touring Car series. His car, meticulously prepared to FIA Appendix K regulations, showcases not only his driving talent but also his deep respect for classic engineering. Under the bonnet lies a 1293cc engine built for revs and reliability, often pushing to 8000 RPM in the heat of competition. A full dog-engagement gearbox and limited slip differential complete a package that perfectly complements Barry’s aggressive yet calculated driving style.

The MINI Campaign: Driving the Past into the Future

Millers Oils’ 2024–2025 MINI Campaign is a celebration of the Mini’s enduring role in automotive history — not just as a cultural icon, but as a legitimate performance vehicle that continues to compete at the highest levels of classic motorsport. Through this campaign, Millers Oils highlights its commitment to specialist lubrication for heritage engines, particularly the A-Series powerplants that power classic Minis. From our renowned Classic Sport 20w50 to the advanced NT+ NANODRIVE technology, our oils are engineered to protect and enhance high-revving, high-pressure vintage engines without compromising their originality. Barry’s Mini is the perfect embodiment of this campaign: lightweight, tightly engineered, and full of character. His continued success in classic racing underscores the role Millers Oils plays in delivering durability, thermal stability, and real-world performance, lap after lap.

Comments from Millers Oils

“Having Barry join us as a Brand Ambassador is a fantastic step forward for Millers Oils classic portfolio,” says Jody Ogden, Automotive Marketing Manager at Millers Oils. “He’s not only a highly respected competitor in the classic racing world, but someone who genuinely understands the demands of maintaining and racing historic vehicles. Barry gives us authentic insight from the track and helps bridge the gap between product development and real-world application.”

“The Mini is a vehicle that stirs up nostalgia and pride in equal measure — and Barry’s connection to it is genuine and deep-rooted. That’s what makes him such a powerful voice for our MINI Campaign. He embodies what Millers Oils stands for: performance without compromise, protection through precision.”

“Built to Perform, Trusted to Protect” — On and Off the Track

Barry’s alignment with Millers Oils goes beyond branding — it’s a genuine collaboration between driver and developer. His feedback from track performance contributes directly to the evolution of our formulations, ensuring that both professionals and enthusiasts benefit from technology proven under pressure.

“Racing a classic Mini isn’t just about speed — it’s about mechanical sympathy, balance, and extracting every ounce of performance,” Barry explains. “That’s why I’ve always trusted Millers Oils — their products give me confidence to push harder and go further.”

Looking Ahead

As Brand Ambassador for 2025, Barry Sime will represent Millers Oils across a calendar of events, including race paddocks, fan engagements, and technical showcases. He’ll also play a key role in sharing insight into how the right oil makes all the difference when it comes to preserving the past while competing in the present.

We’re thrilled to be writing the next chapter of this journey with Barry — a driver who not only understands the heart of the Mini but lives and breathes the values that define Millers Oils. We’ll be sharing more about Barry Sime and Sime Racing as the season unfolds, here on the Millers Oils News Hub and across our social media platforms.
