AMSOIL Signature Series 0W-40 Synthetic Motor Oil

Amsoil Signature Series 0W-40 is a synthetic motor oil from the AMSOIL premium product line “Signature Series 100% Synthetic Motor Oil.” The US-based company Amsoil Inc. has been shaping the international lubricant business for decades. The company’s slogan, “First in Synthetics,” reveals that Amsoil was the manufacturer of the first API-certified synthetic motor oil and has since been recognized as a producer of high-quality automotive, motorcycle, and industrial lubricants, pioneered by its Signature Series products.

What makes AMSOIL Signatures Series 0W-40 special?

Amsoil Signature Series motor oils are fundamentally composed of a synthetic base oil combined with premium additives – this represents the foundation of modern motor oils and is also found in all other synthetic oils. The decisive factor is the effect achieved by the Signature Series technology:

Signature Series engine oils are optimized for cleaning and wear protection !

Compared to the engine oils of the Amsoil OE product line, which already meet the approval requirements of a large number of European automobile manufacturers, the Signature Series engine oils achieve up to 50% higher cleaning effectiveness.

Amsoil Signature Series engine oils are designed for use with extended service intervals. The most important requirement for this is extended wear protection. Amsoil strives to keep this as high as possible. An HTHS value of 3.76 mPas  combined with a TBN of 12.5 mg KOH/g  speaks for itself.

Effective protection against LSPI (Low Speed Pre-Ignition) problems

Amsoil tests Amsoil Signature Series motor oils according to the testing procedure required to achieve GM dexos1 Gen 2 approval, which was introduced  exclusively to address the LSPI issue in smaller turbocharged engines. They are therefore suitable for preventing damage caused by low-speed pre-ignition .

High cleaning effect for engine and turbocharger

The Amsoil Signature Series is formulated for demanding applications—those characterized by high temperatures and material friction. The primary requirements for such a formulation are therefore good protection against heat, deposits, and wear! AMSOIL Signature Series oils are designed precisely for this purpose. By using high-quality heat and wear protection additives , they contribute to increasing the service life and consistent performance of your engine.
