New Mobil 1 Turbo Diesel Truck Motor Oil Delivers Outstanding Engine Performance for Everyday Extreme Driving

New Oil Meets or Exceeds CJ-4 and API SM Industry Standards

FAIRFAX, Va.--(BUSINESS WIRE)--

Further growing its line of premium motor oils, ExxonMobil has introduced a new formulation of Mobil 1 Turbo Diesel Truck 5W-40. This fully synthetic motor oil meets or exceeds the CJ-4 and API SM industry standards and continues the tradition of Mobil 1 products that maximize engine performance and help extend engine life.

"Turbo diesel engines are often asked to work very hard," said Giovanna A Bernal, PVL Product Offer Advisor, ExxonMobil Lubricants and Petroleum Specialties Company, a division of Exxon Mobil Corporation. "Mobil 1 Turbo Diesel Truck motor oil is engineered to provide outstanding wear protection under extreme conditions, such as hauling, towing and off-road driving. At the same time, this motor oil delivers the same excellent performance during the everyday extremes of stop-and-go driving."

Mobil 1 Turbo Diesel Truck motor oil is formulated with SuperSyn, an advanced anti-wear system, and is recommended for use in diesel-powered light- and heavy-duty trucks built by Ford, General Motors, GMC and Dodge. It meets or exceeds the manufacturer requirements for light-duty diesel engines such as Powerstroke, Duramax and Cummins; and heavy-duty diesels such as Mack, Detroit Diesel, Caterpillar and Navistar. It also is compatible with engines built to meet pre-2007 industry standards.

    Other key benefits of Mobil 1 Turbo Diesel Truck include:

    --  Excellent thermal and oxidation stability, which reduces
        low-temperature sludge buildup and high temperature deposits.

    --  The ability to maintain viscosity in severe, high-temperature
        conditions.

    --  Outstanding resistance to corrosion, which helps extend the
        life of critical engine parts.

    --  A wide viscosity range, allowing it to protect at high
        temperatures while also delivering easy starts in cold
        temperatures.

    --  Enhanced levels of oil film strength at high temperatures,
        helping provide increased protection against engine scuffing
        and bore polishing.

Mobil 1 Turbo Diesel Truck 5W-40 motor oil is available in gallon jugs and quarts at retailers nationwide.
