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.

0W-16 Applications

0W-16 (AZS): API SP (Resource Conserving), SN Plus, SN…; ILSAC GF-6B

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 0W-16 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.

ASTM D5293 cold Crank (Lower = Better)

 

Cold Crank Viscosity Crank relationship chart. AMSOIL leads because they have no stockholders to skimp in additive costs.

Cars using 0W-16 often run at full torque without a chance to warm up. Lower is better. Higher viscosity readings at start-up are NOT Acceptable.

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.

bearing wear stopped. This is why AMSOIL always feels smoother from the moment of the oil change.

PTesting conducted in an independent lab using AMSOIL Signature Series 5W-30 Synthetic Motor Oil and a leading synthetic-blend 5W-30 motor oil in Ford F-150 trucks with 3.5L twin-turbo engines.


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

Signature Series 0W-16 Protects Against LSPI

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

The majority of brands fail – you can actually have 4 out of 5 failures to pass the test (or for certification). AMSOIL had Zero failures for the duration.

LSPI is a serious issue and there is no exposure on the truth of how an oil can pass. 4 out of 5 failures means you pass. AMSOIL is the only one with a 100% no failure rate.

BBased on zero LSPI events in five consecutive tests of AMSOIL Signature Series, XL and OE 5W-30 Motor Oil in the LSPI engine test required by the GM dexos1 Gen 2 specification.


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

Sequence IIIH Engine Test – Lower number = better viscosity control

Signature Series 0W-16 Helps Keep Engines Cleaner

  • Our 0W-16 is fortified with a heavy treatment of detergent additives, delivering 28% more acid-neutralizing power than Mobil 1* and helping engines stay cleaner, longer.
  • 50% more detergents to help keep oil passages clean and promote oil circulation.
  • Controls heat and minimizes performance-robbing deposits.
  • Superior thermal durability that resists breakdown and keeps pistons clean.
  • Provides 90% better protection against sludge.DD

Amsoil is The Best. #1 With Me.

By  PHIL,  a  Verified Buyer  on  July 10, 2024
Many years ago I tried Quaker State and Pennzoil once. Was using Valvoline and came across Lucas Oil Products. I thought that there has to be a better way than combining the Valvoline and Lucas Oil Products when doing an oil change. Was in a Local Auto Parts Store and came across Amsoil. Been a good 20+ years now that I have consistently used just the Amsoil oil. When Amsoil came out with the Signature Series I started using that and always do to this day. My car is a 2003. Since using Amsoil Oil the fluid level on the dipstick has not ever varied. Amsoil is also in my Differentials and in the Same Factory Transmission since 2003. Here we do have the Hot Summers and the Cold Winters. Like it or not here even being on the Highway is more-often-than-not, often stop and go just like being on the surface streets. That is why I have Amsoil fluids in my car purposely when driving is not always smooth steady driving. Thank You. Differential fluid is always right where it was when it was changed and needs to be. Transmission fluid on a very Hot and Humid Day with some Highway and Unfortunately some stop and go city construction driving is right where it should be RIGHT AT FULL HOT. No deviation. Oil Cold is right at the Full mark where it should be and stays.

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!
