ExxonMobil Joins AMSOIL® in the Extended Oil Drain Push

For the first time since AMSOIL INC. introduced the concept of "extended drain" oil 33 years ago, another major brand of oil has entered the extended drain arena, a further push toward changing the length of oil drain intervals forever. Last week ExxonMobil introduced its new 15,000 mile oil. AMSOIL INC. of Superior, Wisconsin, globally recognized as the first fully synthetic oil to meet American Petroleum Institute service requirements, has been designing and manufacturing the extended oil change motor oil since 1972. From that time to the present AMSOIL has touted a 25,000 mile or one year oil change interval.

According to AMSOIL Vice President Alan Amatuzio, the introduction of ExxonMobil extended drain oil is long overdue. "We're pleased that another company has finally stepped up to the plate," said Amatuzio. "ExxonMobil's move, which supports AMSOIL INC's extended drain intervals, will be seen as a significant moment in lubricant history and valuable for consumers who are going to benefit from this overall shift in the market."

By the late 1990's most large oil companies offered a synthetic motor oil in their product line, but none of these companies other than AMSOIL pushed drain intervals beyond the 3,000 mile change recommendation. Average oil change intervals in Europe are 10,000 miles with many vehicles recommending 15,000 mile and longer change intervals. The shorter U.S. drain interval results in millions of gallons of unneeded oil production and more than a billion dollars a year in consumer spending.

The environmental benefits of extended drain intervals include reduced packaging waste, use of natural resources and greatly reduced need for disposal of used oil. In addition, independent tests have demonstrated improved fuel economy when synthetic lubricants are used in the engine and throughout the drivetrain.
