Mobil Mobilux EP 1 NLGI 1 Extreme-Pressure Grease 13.7 oz Cartridge — Tan, Low-Temp Pumpable

Mobilux EP 1 is a tan, lithium-thickened NLGI 1 extreme-pressure grease formulated for centralized lubrication systems and low-temperature service. Mobilux EP 1 delivers consistent film strength and wear protection where moderate loads and low ambient temperatures are present. This mineral-oil-based grease offers a dropping point of 190°C and a Timken OK load of 40 lb., packaged in a 13.7 oz cartridge for easy installation in standard grease guns and centralized equipment. The formulation balances pumpability and adhesion so components run smoothly at temperatures down to −20°F and up to about 120°F.

How does this grease perform in cold starts and low temperatures?

Mobilux EP 1 is designed with a softer NLGI 1 consistency that improves pumpability and flow at low temperatures. The lithium soap thickener helps maintain a stable grease structure so the lubricant reaches bearings and fittings quickly during cold starts.

• Minimum operating temperature: −20°F (improved low-temp pumpability)
• Softer NLGI 1 grade for easier distribution through lines and fittings
• Compatible with centralized lubrication systems for reliable delivery

Will it protect bearings and components from wear under load?

Mobilux EP 1 contains extreme-pressure additives and a mineral oil base that reduce metal-to-metal contact under moderate loads, lowering wear. Bench data like a 0.40 mm four-ball wear scar and a 40 lb. Timken OK load indicate solid protection for general industrial applications.

• Four-ball wear: 0.40 mm (low wear tendency)
• Timken OK load: 40 lb. (resistance to mild-to-moderate loads)
• Formulated for bearings and sliding surfaces in light-to-medium duty equipment

How is the product packaged and applied?

This grease is supplied in a 13.7 oz cartridge that fits standard grease guns and many centralized lubrication pumps. The cartridge format minimizes contamination and simplifies topping off or scheduled relubrication cycles.

• Container: 13.7 oz cartridge for grease guns and pump-fed systems
• Tan color grease makes visual inspections straightforward
• Easy replacement and clean handling reduce downtime

What compatibility and operational limits should I know?

Mobilux EP 1 is a lithium-thickened, mineral-oil grease; it pairs well with many conventional greases but check compatibility before mixing different chemistries. It's not NSF-rated and has a typical operating range up to about 120°F; avoid use above the recommended maximum for long-term service.

• Grease thickener: lithium — verify mix-compatibility with existing greases
• Not NSF-rated — not qualified for food-contact lubrication applications
• Recommended max operating temperature: around 120°F for extended service

Who is this for? Mobilux EP 1 is suited to maintenance technicians, plant engineers, and service contractors who need a reliable, pumpable grease for centralized systems and equipment that faces low-temperature starts and moderate mechanical loads. It’s a practical choice for factories, light industry, fleets, and off-road equipment where a dependable lithium-based extreme-pressure grease in an easy-to-use cartridge is required. If your application demands higher temperature stability, NSF food-grade approvals, or specialty synthetics, consider reviewing alternative grades in the Mobilux family or consulting product datasheets for the best fit.
