Mobil 1 Advanced Fuel Economy Motor Oil Offers Fuel Savings and Reduced Greenhouse Gas Emissions

Could Help Reduce US Gasoline Consumption

IRVING, Texas--(BUSINESS WIRE)--

ExxonMobil today announced the national launch of Mobil 1 Advanced Fuel Economy, a synthetic motor oil that could save consumers fuel and benefit the environment by reducing greenhouse gas emissions.

"Helping improve energy efficiency in modern gasoline engines, Mobil 1 Advanced Fuel Economy improves fuel economy by up to 2 percent(1) compared against 5W-30 and 10W-30 engine oils," said Alan Kelly, president, ExxonMobil Lubricants & Specialties Company.

If just one-third of U.S. motorists reduced their gasoline consumption by 2 percent, almost 1 billion gallons of gasoline and 8 million tons of carbon dioxide emissions would be saved every year. This would be equivalent to taking around 1.5 million cars off the road.

With significant expansion in distribution, Mobil 1 Advanced Fuel Economy is now being made available to consumers across the U.S. in major auto and retail outlets.

Addressing the trend of car manufacturers moving to lower viscosity oils, the two Mobil 1 Advanced Fuel Economy products meet or exceed warranty requirements for most GM, Ford, Chrysler, Honda, Toyota, Mazda and many other imports. Mobil 1 Advanced Fuel Economy 0W-20 is recommended by ExxonMobil for 5W-20 applications and Mobil 1 0W-30 is recommended for 5W-30 and 10W-30 applications.

Mobil 1 Advanced Fuel Economy builds on a tradition that goes back over thirty years of providing outstanding protection against engine wear, under normal and extreme conditions. At the same time, it provides better fuel economy that comes from lower viscosity, since less energy is required to circulate the oil. That leaves more energy to drive your car forward.

Look for Mobil 1 Advanced Fuel Economy at leading retailers and auto parts stores including Wal-Mart, AutoZone, Advance Auto, Checker, Schucks and Kragen.

Based on a comparison versus those grades most commonly used and a potential 2% fuel economy improvement. Actual savings are dependent upon vehicle/engine type, outside temperature, driving conditions, and your current engine oil viscosity.
