Reduce Dependency on Foreign Oil
"We can reduce the dependency on foreign oil by using synthetic oils and lubricants in our vehicles. Amsoil is 100% American made and manufactured. Amsoil puts less waste back in the environment, and it saves gas. This is a WIN-WIN combination for America right now. Let's do our part to reduce our dependency on Middle Eastern Oil." AMSOIL gives a 5% increase in fuel economy on average, and in some cases 20% and even more! Why use ordinary oils when our superior AMSOIL synthetic oils outperform all others? AMSOIL Synthetic Oil achieves superior lubrication, extends engine life by reducing friction and wear and creates more horsepower.
