Mobil 1 is a leading performance lubricant brand with deep roots in US motorsport, playing a key role in the IMSA WeatherTech SportsCar Championship.

As a long-time technical partner to top teams and manufacturers, Mobil 1 supplies advanced synthetic engine oils engineered to deliver maximum performance, durability, and efficiency in extreme endurance racing conditions.

Through its IMSA involvement, Mobil 1 reinforces its reputation for protecting engines under the toughest conditions, while supporting innovation in areas like fuel efficiency and hybrid-era performance.

Mobil 1 has a long-standing technical and commercial relationship with Action Express Racing, supplying high-performance lubricants to support engine reliability and performance in endurance racing.

Beyond its technical role, Mobil 1 is also a prominent branding partner, most visibly through special Sebring liveries on the No. 31 Cadillac Whelen. These designs often incorporate Mobil 1’s black-and-silver colour scheme and bold logo placement, celebrating the partnership at one of IMSA’s most demanding races, the 12 Hours of Sebring.

The Sebring liveries serve both as a marketing showcase and a technical statement, highlighting Mobil 1’s role in helping the team withstand extreme heat, bumps, and sustained high loads—conditions where lubrication performance is critical.
