Our purpose is to provide our customers with the highest quality 100% synthetic motor
oil in the world.  It is our opinion that AMSOIL is the absolute best 100% Synthetic
Lubricants in existence (based on ASTM Tests and 30 years of proven efficiency).

We strive to educate and help people understand that synthetic lubricants are so
much better than petroleum based lubricants that they actually save each of us money.

We want to reduce our dependency on foreign oil by showing the public that extended
drain intervals work and that getting better fuel mileage with AMSOIL will make a big
difference.

We want to show you how to protect our environment by using Amsoil synthetic
lubricants.  
Using extended drain intervals and putting much less waste oil back into
the environment.

We want you to be able to drive your car, truck or fleet as far as possible with the least
amount of downtime and reduce your maintenance cost per vehicle in the process.  

We want to provide a way for commuters to extend the life of their commute vehicle,
get better gas or fuel mileage and only have to change oil once every year.  With the
ultra fine less than one micron filtration system you only have to change the Amsoil
bypass filter and Amsoil full flow filter once a year and you don't have to change oil for
100,000 miles or longer with oil analysis.  We want you to saving money and time and
extend the life of your vehicle or fleet.

We want you to use your free time playing with your children, grandchildren or doing
what you want to do on your weekends.  Rather than having to change oil 6 to 8 times
a year sitting at a dealership or garage or having to change your own oil
on your
time off
.

Our main goal is to provide you with quality service.
