AMSOIL Z-Rod Synthetic Engine Oil
AMSOIL Z-ROD Synthetic Motor Oil is specially formulated for classic, vintage and high-performance vehicles. Its high-zinc formulation provides enhanced protection for flat-tappet camshafts and other highly loaded engine components commonly found in older and performance engines.
Z-ROD is also engineered with rust and corrosion protection for vehicles that may spend extended periods in storage, making it particularly well suited to classic, collector, muscle and enthusiast vehicles that are driven seasonally or infrequently.
AMSOIL Z-ROD Synthetic Motor Oil for Classic and Performance Engines
AMSOIL Z-ROD Synthetic Motor Oil is engineered specifically for classic, vintage, performance and enthusiast vehicles, including engines that can benefit from the additional anti-wear protection provided by a high-zinc engine oil. It combines synthetic lubricant technology with a formulation designed around vehicles that may differ significantly from modern daily-driven engines.
High-Zinc Protection for Older Engine Designs
Many older engines use flat-tappet camshafts, where the interface between the cam lobe and lifter can experience high contact loads. Zinc and phosphorus anti-wear chemistry, commonly associated with ZDDP, can play an important role in protecting these components.
Modern engine oils are primarily developed around the requirements of modern engines and emissions systems. That does not make modern oils inherently unsuitable for every older vehicle, but it does mean enthusiasts should consider the lubrication requirements of the particular engine rather than selecting oil solely by viscosity.

Designed for Vehicles That Spend Time in Storage
Classic and enthusiast vehicles are often driven differently from daily transport. They may sit unused for extended periods, cover relatively few kilometres each year or operate seasonally. Z-ROD is designed with these usage patterns in mind, providing a specialised lubricant option for vehicles where both operation and storage form part of the service environment.
Choose the Correct Z-ROD Viscosity
Engine age alone does not determine the correct viscosity. Consider the engine design, clearances, modifications, operating conditions and builder or manufacturer recommendations when selecting an oil. Browse the available Z-ROD viscosity grades above to choose the product appropriate for your classic or performance engine.
