Motul and RUF Automobile have introduced a co-branded 20W-50 heritage motor oil designed specifically for classic air-cooled engines. The product made its debut at the 2026 Goodwood Revival as part of an ongoing partnership that began in 2020.
Why it matters
Classic engines often require specific lubricant formulations that differ from modern synthetic oils to ensure optimal performance. This specialized product leverages shared engineering data to protect internal components in both naturally aspirated and forced-induction engines.
The lubricant is sold in 2-litre heritage metal cans and is compatible with both carburettor and fuel-injection systems. It is formulated for vehicles produced between the 1950s and the 1970s.
The players

Founded in 1853, this French company is a global manufacturer of high-performance motor oils and industrial lubricants present in 160 countries.
RUF Automobile
Based in Pfaffenhausen, Germany, and founded in 1939, this manufacturer is world-renowned for its specialized performance vehicles and engineering services.
The details
The collaboration utilizes technical engineering data to support various engine types, including supercharged and turbocharged configurations. RUF Automobile, based in Pfaffenhausen, Germany, has worked with Motul to ensure the mineral multigrade oil meets the unique operating requirements of vintage machinery.

Roadmap
This release reflects an industry-wide trend where manufacturers provide specialized aftermarket support to maintain the integrity of historic vehicle fleets. By focusing on niche mineral formulations, these brands differentiate themselves from mass-market lubricant competitors.
