Schaeffer Ultra Red Supreme Grease NLGI #2 - Heavy-Duty, High-Temp

In this review of Schaeffer Ultra Red Supreme Grease NLGI #2 the bottom line is simple: this is a heavy-duty, extra tacky grease built for equipment that sees severe pressure, heat, moisture and mechanical action. The reviewer found it especially useful for construction, mining and agricultural machines where staying in place and resisting washout matters most. Fortified with moly and formulated as an aluminum complex para-synthetic, it delivers extended protection and reduced friction, which makes it worth considering when conventional greases fail under strain.

Key Features

• Pressure resistance: Remains effective under extreme loads and is specified to withstand pressures up to 500,000 psi, protecting surfaces during heavy contact.
• High temperature capability: Withstands a higher heat range than conventional greases, performing at temperatures up to 250F higher before breakdown.
• Cold start performance: Still hand pumpable at temperatures as low as 30F, so it can be applied in colder jobsite conditions without special equipment.
• Adhesion and tack: Extra tacky aluminum complex formula retains grease-like consistency during severe mechanical action and resists washout and splatter.
• Friction reduction: Fortified with moly to reduce friction and wear, lowering contact area temperature and extending component life.

Who It's For

This grease is aimed at professionals and fleet managers running heavy-duty automotive, construction, mining, farming and industrial equipment that require a clean, tacky lubricant able to resist pounding, washout and extreme loads. Its hand pumpable low-temperature behavior and higher heat tolerance make it practical for jobsite use across seasons.

It is not recommended for passenger car wheel bearings or electric motor bearings, so owners of light passenger vehicles or precision electric equipment should look for greases specifically formulated for those bearings instead.

Pros & Cons

Pros

• Exceptional adhesive properties resist washout, so lubrication stays where it is applied under heavy use.
• High pressure tolerance and moly fortification reduce wear and lower operating temperatures of contact areas.
• Wide operating window with higher heat resistance and hand pumpability down to 30F increases versatility in varied environments.
• Aluminum complex para-synthetic base provides longer-lasting protection than conventional greases.

Cons

• Not suitable for passenger car wheel bearings or electric motor bearings, so it is not an all-purpose shop grease.
• Pack quantity and format may be excessive for small-scale users who need small tubes or cartridges.

Our Verdict

For fleets and heavy-equipment operators who need a durable, tacky grease that stands up to extreme pressure and heat, Schaeffer Ultra Red Supreme Grease NLGI #2 is a reliable choice that offers long-lasting protection and reduced wear thanks to its moly fortification. It represents strong value for industrial and agricultural applications, though those needing grease for passenger car wheel bearings or electric motors should choose a purpose-built formula.

Frequently Asked Questions

Can this grease be used in cold climates?
Yes; the formula is hand pumpable in temperatures as low as 30F, making it usable in many cold-weather jobsite conditions.

Is this suitable for all bearings?
No; it is not recommended for passenger car wheel bearings or electric motor bearings and should be reserved for heavy-duty equipment applications.

What benefit does moly provide?
Moly reduces friction and wear under heavy loads, helping to lower contact area temperature and extend component life.
