0W-16 Applications

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

Signature Series 0W-16 Fights Engine Wear

  • 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.

ASTM D5293 cold Crank (Lower = Better)

PPBased on independent third-party testing in the industry-standard ASTM D5293 Cold Crank Simulator test as required by SAE J300.

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 is eliminated with AMSOIL - Gail Banks says when Magnafluxing parts, only engines that used AMSOIL show no cracks. The oil buffers the vibrations allowing more power to the wheels.

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.


Signature Series Protects Against LSPI

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

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 0W-16 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

Signature Series 0W-16 Helps Keep Engines Cleaner

  • Fortified with a heavy treatment of detergent additives, delivering 28% more acid-neutralizing power than Mobil 1* and helping engines stay cleaner, longer.LL
  • 50% more detergentsD 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

Better running engine and less oil burning than Mobil 1.

By  JERAMEY,  a  Verified Buyer  from  Illinois  on  July 02, 2024

Very pleased with Amsoil. It’s expensive but it has less evaporative loss and it’s still new looking at 1500 miles. I still wouldn’t recommend going over 5 to 7000 miles on any oil


Amsoil For Life! Period!

By  JOSEPH,  a  Verified Buyer  from  New York  on  June 27, 2024

I recently had the little 5.3 L83 in my 15 Silverado freshened up with goodies from BTR, Frankenstein, GM Performance and the list goes on. Engine Dyno’d at 450 whp. At 8,000 RPM. I was using mobile 1 oil but at high rpm it didn’t feel smooth so I rarely got on it. Until I changed to the Amsoil Signature Series OW-20. Now I do multiple pulls to 8,000 a day and the engine runs smooth as glass, also haven’t been burning as much E85 either. I’ll never use an other oil again and can’t wait to change my transmission fluid to Amsoil as well. Performance oil! Insane!


Like new car!

By  CLAYTON,  a  Verified Buyer  from  Ontario   on  April 24, 2024

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!
