AMSOIL Signature Series 0W-20 100% Synthetic Motor Oil, 1 Quart

AMSOIL Signature Series 0W-20 is a 100% synthetic motor oil for drivers who want the strongest engine protection AMSOIL offers. It combines advanced synthetic base oils with a precision additive system to control wear, resist volatility and hold its viscosity under extreme heat, pressure and cold starts. It is aimed at modern turbocharged and direct-injection engines.

What it does

• Protects: long-life anti-wear protection.
• Cleans: fights sludge and carbon buildup.
• Adapts: responds to changing operating conditions.
• Performs: AMSOIL's tests go beyond the industry standard.

AMSOIL's published test results

• About twice the protection against volatility compared with the API SQ limit (Noack test, run on the 0W-20).
• Four times the piston protection against low-speed pre-ignition (LSPI) than the standard requires, even after 25,000 miles of use (Sequence IX aged-oil test, run on the 5W-30).
• 72% more protection against piston deposits than the standard requires in the Sequence IIIH test, and 31% better protection after doubling the test length.
• No oil screen plugging in a 125,000-mile accumulation study in a 2025 Ford F-150 Raptor.
