Low-viscosity motor oil formulated to comply with EU emission mandate

FAIRFAX, Virginia -- Automotive manufacturers across Europe are struggling with the challenge of meeting stricter EU emission reduction mandates without sacrificing vehicle performance? A team of Mobil 1 lubricant experts at ExxonMobil Research and Engineering saw an opportunity to achieve significant carbon dioxide emission reductions through the development of a low-viscosity motor oil that did not sacrifice engine protection.

The project team set out to develop a new Mobil 1 formulation that offered the performance benefits of high-viscosity motor oils with the fuel efficiency gains of low-viscosity formulas.

“The key to getting the most out of a lubricant is maximizing the contribution of each component in the formulation,” said Doug Deckman, Ph.D., Mobil 1 lead researcher. “With our process of selecting and evaluating individual components and additives, we were very confident that we could create a low-viscosity formulation to deliver step-out fuel economy performance without sacrificing performance elsewhere in the engine.”

The team’s efforts resulted in Mobil 1 ESP x2 0W-20, a motor oil that is actually green in color, differentiating it from other Mobil 1 formulations. During development, they documented that the innovative, low-viscosity synthetic motor oil could help improve fuel efficiency—up to 4%—without sacrificing performance and durability of gasoline- and diesel-powered engines.

Jaguar Land Rover, Porsche and Volkswagen Group have all approved the new Mobil 1 formulation that is now commercially available. Karl Dums, director of advanced engineering powertrain and powertrain strategy at Porsche, said, “The low-viscosity formulation of Mobil 1 ESP x2 0W-20 offers the compelling performance benefits demanded by our premium vehicles, as well as improved fuel efficiency for our drivers.”
