AMSOIL Z-ROD™ SAE 10W-30 Synthetic Motor Oil

AMSOIL Z-ROD™ Synthetic Motor Oil is specially engineered for classic and high-performance vehicles. It features a high-zinc formulation to prevent wear on flat-tappet camshafts and other critical engine components, along with a proprietary blend of rust and corrosion inhibitors for added protection during long-term storage. Z-ROD Synthetic Motor Oil is designed to perform on the street and protect during storage. The lifters and cam lobes on flat-tappet camshafts common to classic and high performance vehicles slide rapidly against one another, producing high friction and heat. The friction between the two components can eventually wear down the cam and affect valve operation, ultimately resulting in lost engine power and reduced efficiency. In addition, these areas are splash-lubricated rather than pressure lubricated like other areas of the engine, which adds extra strain on anti-wear additives like the zinc and phosphorus in zinc dialkyldithiophosphate (ZDDP).

Four-stroke gasoline engines have long been a mainstay of the general marine industry. They have succeeded in reducing emissions and increasing fuel efficiency, and they have also been a hit with consumers. When four-stroke outboard motors were introduced to the market, manufacturers recommended either their own specially formulated oil or an API SG or SL automotive oil. However, because the specific lubrication requirements of automobiles and outboard motors are different, it soon became apparent that four-stroke outboard motors would require their own oil specification. This standard, entitled FC-W, was released by the National Marine Manufacturers Association (NMMA) in August 2004.

AMSOIL WCF and WCT are both NMMA Certified, demonstrate outstanding performance, and exceed the NMMA "FC-W" (Four Cycle - Water) specification requirements:

AMSOIL Synthetic Stationary Natural Gas Engine Oil

 MSOIL Synthetic Stationary Natural Gas Engine Oil delivers continuous protection in stationary natural gas engines calling for an SAE 40, low-ash lubricant. Its shear-stable formula qualifies it as a multi-grade 20W-40 so it can be used over a broad ambient temperature range, eliminating the need for seasonal oil changes. AMSOIL Synthetic Stationary Natural Gas Engine Oil is formulated with low sulfated ash to minimize carbon deposits and port blockage, resulting in reduced maintenance and extended equipment life. Advanced anti-wear and anti-scuff protection helps control valve recession and wear on piston rings, cylinder liners and bearings during continuous severe-service operation in stationary natural gas engines. May be used for extended drain intervals when monitored by an oil analysis program. Should NOT be used in automotive engines or vehicular engines that run on propane or natural gas: see AMSOIL Synthetic Vehicular Natural Gas Engine Oil (ANGV) for these applications.
