Air Filters
Your car runs on a mixture of air and fuel, actually, 14.7 times more air than fuel. Any restriction in airflow has a dramatic, negative impact on fuel economy. In addition, an air filter is supposed to remove dirt, especially the smaller particles which actually cause the most damage. The AMSOIL foam filter is the only filter that accomplishes both tasks, is washable and the AMSOIL filter lasts as long as your vehicle.
Transmission Fluid
Here is a fluid that most folks forget about- though it needs to be changed every 20,000-50,000 miles. Elevated transmission temperatures can destroy all lubricating properties of a fluid within a few hundred miles, then destroy the transmission. This usually costs the consumer $1200-$2500 to fix.
AMSOIL transmission fluids last 3 times longer, reduce heat from 20-80 degrees and keep sensitive components free from deposits. These three things ensure longer lasting, more reliable, smoother shifting transmissions.
