The Science Behind Synthetic Protection

Traditional mineral oils contain various molecular sizes and impurities that can break down under heat and stress. Full synthetic oils like Amsoil’s 0W-40 feature uniform molecular structures, which means they are inherently more stable.

This stability translates to superior resistance against thermal breakdown, oxidation, and sludge formation. The uniform molecules also allow the oil to flow more easily at cold temperatures and maintain its viscosity at high temperatures, offering consistent protection.

Why 0W-40? Understanding Viscosity

The “0W-40” designation refers to the oil’s viscosity grade, as defined by the Society of Automotive Engineers (SAE). The “0W” (W for winter) indicates how the oil performs at cold temperatures.

A 0W rating means the oil is exceptionally thin when cold, allowing it to circulate rapidly at startup. This rapid circulation is crucial for protecting engine components during the critical first few seconds of operation, especially in colder climates.

The “40” refers to the oil’s viscosity at operating temperature. A 40-weight oil offers a robust film strength to protect against metal-to-metal contact when the engine is hot and working hard. This dual-grade capability ensures comprehensive protection from extreme cold starts to high-heat, heavy-load operations.
