Phillips 66® Transmission Oil SAE 90 is an SAE 90 mineral oil gear lubricant recommended for use in manual transmissions, transfer cases and rear axle assemblies of automotive, farm and off-highway equipment where the manufacturer specifies an API GL-1 gear oil. It also may be used in light-duty industrial applications where a non-compounded ISO VG 150 or AGMA 4 mineral oil is specified.
• Good film strength for wear protection
• Good oxidation resistance
• Protects against rust and corrosion
• Good foam resistance
• Heavy-duty, multiple-speed manual transmissions and transfer cases in trucks and buses where the manufacturer specifies an API GL-1, SAE 90 gear oil
• Lightly loaded enclosed industrial gear drives where the OEM specifies a R&O type, AGMA 4 gear oil
• General-purpose lubrication in applications that require a non-compounded, ISO VG 150 mineral oil
Mineral Gearlube 90 meets the requirements of:
• API Service GL-1
