According to AMSOIL Vice President Alan Amatuzio, the introduction of ExxonMobil extended drain oil is long overdue. "While AMSOIL INC. has certainly proven that extended drain intervals provide valuable benefits," said Amatuzio, "the fact that ExxonMobil is finally saying the same thing brings the message to even more people. ExxonMobil's move is significant in that more consumers will now recognize AMSOIL as the pioneer in extended drain oils and will benefit from the advanced technology we introduced 33 years ago."

Motor oil technology has gradually progressed since the days of the earliest automobiles. In those days, standard motor oil drain intervals were between 500 and 1000 miles, and motorists had to switch viscosity grades with the changing of the seasons. The development of oil filtration and additive technology in the 1930s allowed drain intervals to increase to 2000 and later 3000 miles, while the development of viscosity modifiers in the 1940s allowed the formulation of multi-grade oils that could be used in both hot and cold temperatures.

AMSOIL has always formulated its products to be the absolute best, continually researching ways to make its already outstanding products even better. Other oil companies, however, are beholden to shareholders, and one could speculate that their incentive is to maximize profit. They formulate oils down to a price, rather than formulating them to be the best they can be. Then, they price their products to maximize profits. In addition, AMSOIL has 33 years of experience blending premium extended drain synthetic oils. That’s 33 years worth of proven performance in the field.

A close look at ExxonMobil’s new long drain motor oil line reveals that two are petroleum based, one is a synthetic blend and only one, Mobil 1 Extended Performance, is a full synthetic. The petroleum based products are recommended for 5000 mile drains, the synthetic blend for 7500 mile drains and Extended Performance for 15,000 mile drains. However, a look at the fine print reveals that ExxonMobil is still recommending drivers follow the oil drain recommendations listed in their owners manuals during the warranty period. AMSOIL synthetic motor oils are recommended for 25,000 mile or one year drain intervals in both new and older vehicles. The AMSOIL warranty stands behind this recommendation.
