AMSOIL Synthetic Motor Oil has superior heat
and oxidation resistance Extends Oil Life
The Thin Film Oxygen Uptake Test (TFOUT) is used to evaluate engine oil's ability to resist heat and oxygen breakdown when contaminated with oxidized/nitrated fuel,
water, and soluble metals such as lead, copper, iron, manganese and silicon. This test is designed to mimic the operating conditions of a gasoline engine.
AMSOIL 10W-30 Synthetic Motor Oil has superior heat and oxidation resistance to control sludge deposits and extend oil life. Engines stay clean for maximum
protection and oil changes are reduced, saving time and money.
Protects Hot Engines
The High Temperature/High Shear Test measures a lubricant's viscosity under severe high temperature and shear conditions that are similar to severe service
applications in an engine. In order to prevent wear, it is important for a lubricant to maintain its protective viscosity level under severe operating conditions.
AMSOIL 10W-30 Synthetic Motor Oil does not "shear back" and thin out like other motor oils. Its superior viscosity stability provides unsurpassed bearing
protection for dependable engine operation, especially during hot operating conditions.
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service Maximizes Fuel Economy, Reduces Oil Consumption and
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they
become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions.
AMSOIL 10W-30 Synthetic Motor Oil resists high temperature volatilization (evaporation) better than other motor oils. AMSOIL Synthetic Motor Oil maintains
peak fuel efficiency and reduces oil consumption and emissions.
The Pour Point Test determines the lowest temperature at which a lubricant will flow Improves Cold Temperature Startup
The Pour Point Test determines the lowest temperature at which a lubricant will flow. The lower a lubricant's pour point, the better protection it provides in low
temperature service. Unlike conventional oils that solidify in cold temperatures, AMSOIL 10W-30 Synthetic Motor oil remains fluid down to -58° F. AMSOIL
Synthetic Motor Oil helps engines turn over easier and flows quickly to engine parts for critical start-up protection. Engines start faster and wear is greatly
reduced for extended engine life.
The higher a motor oil's TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended
period of time. Controls Acid Formation
Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity, which aids in the control of acids formed during the combustion process. The
higher a motor oil's TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of
The high TBN of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively combat wear-causing contaminants and acids, providing superior protection and
performance over extended drain intervals.
The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates Helps Engines Start Easier
The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these
conditions is directly related to engine cranking and startability. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold
temperatures. The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical
cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.
The smaller the wear scar, the better the protection.
Nothing Protects Against Wear Like AMSOIL
The Four-Ball Wear Test evaluates the protection provided by engine oil under conditions of pressure and sliding motion. The size of the scar left as a result of the
test determines the amount of wear protection the lubricant provides. The smaller the wear scar, the better the protection. Tests show that AMSOIL 10W-30
Synthetic Motor Oil has better antiwear performance than all other oils tested. With AMSOIL Synthetic Motor Oil, engine life can be extended and major repairs
are often reduced.
A value comparison shows AMSOIL Synthetic Motor Oil costs less than competing motor oils over 25,000 miles. Saves Money
By extending oil drain intervals through its premium formulation, AMSOIL Synthetic Motor Oil saves drivers money. A value comparison shows AMSOIL
Synthetic Motor Oil costs less than competing motor oils over 25,000 miles.
While competing motor oils must be changed up to five times over 25,000 miles, AMSOIL Synthetic Motor Oil is only changed once, saving both time and money.
