AMSOIL 25,000 Mile / One Year Oil Change


For Gasoline and Diesel applications AMSOIL offers extended drain intervals of one year up to 25,000 miles.

Under normal conditions, AMSOIL synthetic motor oil coupled with an AMSOIL EaO oil filter offer one year or 25,000 miles of protection.

Under severe conditions service life is still one full year, but mileage is reduced to 15,000 miles.

Just a few of the benefits of using AMSOIL oil and filters.

  • PERFORMANCE - No other motor oil in the world protects an engine like AMSOIL synthetic motor oil.  AMSOIL EaO oil filters are unmatched in filtration technology.
  • CONVENIENCE - Changing your oil once a year frees you up to do the things you never seem to have enough time to do.
  • COST - Using AMSOIL is actually less expensive than a year's worth of petroleum oil changes.
  • ENVIRONMENTAL - Why generate 20 quarts of waste oil and four waste oil filters per year per vehicle when you can use AMSOIL and only generate five quarts and one filter?
  • PATRIOTIC - AMSOIL is a domestically sourced synthetic motor oil.  Every five quart motor you switch to AMSOIL is 20 less quarts of foreign oil per year.

Don't change your own oil?

No worries!  Find an independent service station (gas station, tire shop, etc.) and tell them you want to bring your own oil and that you are willing to pay $10 for their labor.  They will gladly accept.


Ready for the Performance, Convenience, Cost Saving, Environmental and Patriotic Benefits that only AMSOIL offers?

All intervals are for “mechanically sound” equipment defined as - Engines that are in good working condition and within the factory design settings. Mechanically sound engines, for example, do not leak oil or consume excessive amounts, are not worn out, do not over heat, do not have internal or external anti-freeze leaks, and have properly working emission control systems.  AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL Synthetic Motor Oils.


Normal Service defined as - Personal transportation vehicles frequently traveling greater than 10 miles at a time and not operating under severe service.


Gasoline Engine Severe Service defined as - Turbo/supercharged engines, commercial or fleet vehicles, excessive engine idling, first and subsequent use of AMSOIL engine oil in vehicles with 100,000 miles or greater, daily short trip driving less than 10 miles (16km), frequent towing, plowing, hauling and driving in dusty conditions.


Diesel Engine Severe Service defined as - Extensive engine idling, daily short trip driving less than 10 miles (16km), frequent towing, plowing or hauling heavy loads and frequent driving on dusty conditions.


Modifications and Alterations - No extended drain interval recommendations are made where the engine or operating conditions have been changed from the original manufacturer’s design. Oil change intervals are at the owner’s discretion or extended based on oil analysis. Examples include, but not limited to, the use of performance computer chips; modified

exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the equipment manufacturer.
