AMSOIL synthetic diesel oils reduce friction and wear better than conventional oils, helping hard-working diesel engines perform better and last longer. They withstand high-temperature breakdown to help prevent harmful deposits from forming, while remaining fluid in sub-zero temperatures for easier cold starts and nearly immediate circulation and protection.

The "Perks" of Synthetics....
Maximum Fuel Economy – With less resistance to internal moving parts, engines are able to operate at peak efficiency and deliver maximum MPG
Extended Drain Intervals – AMSOIL coined the phrase “extended drain interval” nearly 40 years ago. Advanced chemistries allow extended-drain AMSOIL synthetic diesel oils to remain effective up to three times longer than original equipment manufacturer (OEM) recommendations. Motorists benefit significantly through reduced oil costs and increased convenience through fewer oil changes and less used oil disposal.
AMSOIL synthetic diesel oils’ advanced lubricity (slipperiness) yields better performance and protection

Diesel Fuel Economy
Air and Oil Filtration
Ea® Synthetic nanofiber technology reduces engine wear by providing
ultra-high filtering efficiency for automotive/light-truck applications.
Engine Protection
Filters that trap a higher percentage of smaller wear particles provide increased
engine protection. AMSOIL Ea Oil Filters trap and hold 98.7 percent of particles 15
microns and larger, while competitive filters containing conventional cellulose media range from 40 to 80 percent efficient.
AMSOIL by-pass filtration systems employ a secondary by-pass filter rated 98.7
percent efficient at two microns, nearly eliminating wear-causing particles.
AMSOIL Ea Air Filters’ synthetic media traps and holds five times more dust than
cellulose media alone and 50 times more than wet-gauze type media, helping stop
dirt before it reaches the engine.
Extended Service
Used with AMSOIL Synthetic Motor Oils, Ea Oil Filters have a maximum recommended service life of either 15,000 miles or 25,000 miles, depending on the application. Ea Air Filters provide 100,000 miles/four years of service with annual cleaning using a shop vacuum or compressed air. AMSOIL extended-service filters save motorists time and money.
Drivetrain Fluids
Premium synthetic drivetrain lubricants reduce wear, extend service
life and maximize fuel economy.
Synthetic Transmission Fluids
AMSOIL synthetic transmission fluids withstand the rigors of high-horsepower/hightorque diesels better than conventional fluids. They maintain viscosity for reduced gear and bearing wear and increased equipment life. Their synthetic formulations resist oxidation, varnish formation and sludge build-up to provide superior cooling and lubrication.
Synthetic Gear Lubes
AMSOIL synthetic gear lubes protect heavily loaded
differentials better than conventional lubes. Extreme pressure formulations guard against metal-to-metal
contact for maximum wear control. Their synthetic
chemistries reduce friction and drag for increased fuel
efficiency while providing extended drain intervals.
Synthetic Greases
AMSOIL synthetic greases resist pound-out and washout better than conventional greases. They seal out contaminants and provide superior lubrication throughout extended service intervals.
Diesel Fuel Additives & Engine Coolants
- AMSOIL Cetane Boost – Improves combustion efficiency to increase power in diesel engines. Raises cetane up to seven numbers.
- AMSOIL Cold Flow Improver – Helps prevent icing or gelling in fuel.
- AMSOIL Diesel Concentrate – Cleans fuel system components, increasing fuel economy by up to 5 percent.
- AMSOIL Diesel Concentrate Plus Cold Flow Improver – Reduces cold filter-plugging point as much as 34°F while also maximizing fuel economy.
- AMSOIL Diesel Recovery – Quickly liquefies gelled diesel fuel, thaws frozen fuel filters and reduces the need for a new filter.
- AMSOIL Antifreeze & Engine Coolant – Surpasses standards for metallic corrosion and provides superior
cooling and protection for 250,000 miles/seven years in autos/light trucks.
