AMSOIL Lubricant – Signature Series 5W-50 (AMR)
AMSOIL oils and additives – lubrication is the last place to compromise.

Amsoil is a US-based lubricant manufacturer known for maintaining extremely high quality standards without the cost-cutting measures that have affected many traditional oil brands. The focus is purely on lubrication performance and engine durability.

In our own workshop projects Amsoil is often a requirement, not just a recommendation. A quality oil is the cheapest insurance you can buy for a tuned or heavily loaded engine.

What should you know about this product?

Signature Series (SS) is AMSOIL’s line representing the latest expertise for gasoline engines. Engine protection against wear and power loss is 75% better than required by the stringent API SN oil standard.

In turbocharged direct-injection (GDI) engines, this oil provides 100% protection against harmful Low Speed Pre-Ignition (LSPI). The highly thermally stable synthetic raw materials make it excellently suited for turbo use, protecting the turbocharger 72% better against coking than required by the GM dexos1 Gen 2 specification.

Signature Series contains 50% more detergents and provides 90% better protection against sludge formation. Intended for newer high-performance turbocharged engines, including those running E85.
