Our Story
Built for the Road. Made in America.
ProMEX Motor Oil was founded on a single conviction: American engines deserve American-made lubricants engineered to the highest standard.
Mission
Why We Exist
ProMEX exists to protect every engine that powers American life — from the family sedan to the long-haul fleet truck. We formulate lubricants that meet and exceed the most demanding API and ILSAC certifications, so drivers and fleet operators can trust every drop.
We believe performance should never be a compromise. That's why every ProMEX product is developed in our domestic R&D facilities, tested under real-world conditions, and manufactured without cutting corners.
Vision
Where We're Going
Our vision is to be the most trusted name in American motor oil — recognised not just for performance, but for integrity. We're expanding our product range, growing our distribution network, and investing in next-generation synthetic formulations.
From coast to coast and beyond, ProMEX is committed to keeping engines running cleaner, longer, and stronger.
Brand Values
What We Stand For
Uncompromising Quality
Every batch is tested against API, ILSAC, and internal ProMEX standards before it leaves our facility. No shortcuts. No exceptions.
Made in America
From raw material sourcing to final packaging, our entire production chain is rooted in the USA — supporting American workers and American industry.
Engineering Excellence
Our R&D team works continuously to advance our formulations, staying ahead of evolving engine technology and emissions requirements.
Partnership First
We build long-term relationships with distributors, fleet operators, and retailers — not just transactions. Your success drives ours.
Responsible Manufacturing
We operate our facilities with environmental responsibility in mind, minimising waste and continuously improving our sustainability practices.
Proven Performance
ProMEX products are validated in real-world conditions — on highways, job sites, and racetracks — not just in a laboratory.
Made in the USA
American Manufacturing Standards
Our production facilities operate to the strictest domestic and international standards.
Our state-of-the-art blending and packaging facilities are ISO-certified and subject to continuous quality audits. Every production run is tracked from raw additive to finished product, ensuring full traceability and consistency.
We source base oils and additive packages from trusted American suppliers, maintaining tight control over every variable that affects lubricant performance. The result is a product you can rely on, batch after batch.
