The one 0W-16 Motor Oil That Sets the Standard!

If you need a 0W-16 – you REALLY need Signature Series due to the high stress fuel efficient technology of these engines. All 0W-16’s are synthetic but how much? And how tough are they? Are they blended to “just work”, of for the most profit? Or for a little more protection? Well this one is top of class which is why people go to AMSOIL. Best of class 0W-16.

A New Level of Motor Oil Technology

0W-16 Fights Engine Wear

Our 0W-16 develops a strong fluid film that keeps metal surfaces separated. The robust anti-wear additives further reduce wear in metal-to-metal contact regions for further extended
engine life. Here’s what’s up: The Sequence IVA Engine Test, which must be passed to meet the API SN PLUS specification simulates extended periods of stop-and-go driving. For 100 hours, the test engine cycles between 50 minutes of idling and 10 minutes of elevated rpm — conditions that encourage engine wear. The camshaft is then measured for wear in 84 locations and an average score is determined.

  • 75 percent more engine protection against horsepower loss and wear1 than required by the industry standard, extending the life of vital components like pistons and cams.
  • Develops a strong fluid film that keeps metal surfaces separated.
  • Robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life.

Signature Series Improves Startup Protection

AMSOIL provides better cold cranking viscosity, helping improve wear protection for engine components at startup.PP

This is key for vehicles with stop/start technology.

Signature Series Delivers Powerful Protection

AMSOIL delivers powerful protection. How good is it? An independent lab compared AMSOIL synthetic motor oil head-to-head against a leading competitor in a 100,000-mile test.P AMSOIL provided far superior wear protection and kept bearings looking like new.

A 0W-16 to Preserve Horsepower

The extreme durability of Signature Series Motor Oil helps your engine run stronger, for longer. We installed Signature Series 5W-30 Synthetic Motor Oil in a Ford F-150 with
a new 3.5L Ecoboost engine to test its ability to protect turbocharged direct-injection (TDGI) engines from torque and horsepower loss during extended drain intervals up to 25,000 miles (40,200 km). Power sweeps were done at the beginning and end of the test to evaluate horsepower and torque retention. As the graph shows, Signature Series helped maintain engine  performance throughout the 100,000-mile (160,934 km) test

More Horsepower to the wheels as losses are less with Signature Series


Signature Series Protects Against LSPI

AMSOIL Synthetic Motor Oils achieved 100% protection against LSPI.B

Signature Series Resists Viscosity Increase

Signature Series is barely challenged by the industry-standard testing, demonstrating only a 0.1% viscosity increase. Even when the test length is doubled, AMSOIL delivered twice the viscosity control required by the standard.GG

A great oil for hybrid cars

By ROBERT, a Verified Buyer from Sauk Rapids, MN on July 10, 2024
I use this Signature Series 0W-16 oil in my Kia Niro hybrid car because it’s the best available. A fast flowing oil is needed for hybrids with the gas engine kicking in and out. My only complaint is that it is not yet available in a one gallon jug. I prefer gallon jugs as both my cars take four quarts during an oil change.

Like new car!

Great product, used in both of my vehicles. Really made a big difference in the valve train noise!! Much quieter and runs smoother.

Slippery in all the right places

By  JOHN,  a  Verified Buyer  from  Arizona  on  April 23, 2024
It gets and stays hot where I live. It is also dusty much of the time. So I have to know my engine is getting what it needs to prolong life. Ever since I watched Gail Banks three part tour of the Wisconsin plant, I have come to know that I am using the best lubrication in all my vehicles including a fifteen year old bagger. Using Amsoil is the poor man’s insurance policy!
