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.

Join Now0W-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.
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 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
