Performance Benefits: Why Choose 7067C?

Choosing an EP additive involves balancing protection against thermal degradation. Here is why Lubrizol 7067C stands out.

The Chemistry: The Zinc Debate

One of the most interesting aspects of the 7067C story is its reliance on zinc.

For years, the industry has seen a push toward "ashless" (zinc-free) hydraulic fluids. Zinc can be toxic to the environment, and in applications where a leak might contaminate water or soil, ashless fluids are preferred.

So why does 7067C, a modern product, still rely on zinc? The answer is performance economics.

Zinc-based additives like 7067C offer a superior "load-carrying" capacity at a lower cost compared to many ashless alternatives. For heavy-duty industrial machinery—steel mills, injection molding machines, and mobile construction equipment—the wear protection provided by the zinc in 7067C is often seen as indispensable. It represents the "sweet spot" where maximum protection meets reasonable cost.

Furthermore, Lubrizol engineered 7067C to handle the "yellow metal" corrosion issue that often plagues zinc fluids. Historically, high-zinc fluids could corrode the copper or bronze components in a pump. 7067C includes specific inhibitors that protect these softer metals, solving a historical weakness of zinc chemistry.

Versatile Treat Rates

The product offers formulation flexibility:

Low treat (1.5%): Rust and oxidation inhibited (R&O) oils with mild EP protection.
Medium treat (2.5-3.5%): Standard industrial gear oils (ISO 68 to 460).
High treat (4.5%): Severe duty mining gear oils.

3. Advantages (Pros)

Superior Shear Resistance: In extended drain interval trials (100,000+ miles on-road), lubricants blended with 7067C retained >92% of their original KV100 viscosity. Competing SSI-35 VIIs dropped to 85%. This directly protects against wear in EGR-equipped diesels and high-pressure hydraulics.
Low Handling Complexity: Unlike styrene-butadiene or crystalline VIIs, 7067C is a low-pour liquid concentrate (max 0°C pour point). It pumps easily in cold climates and requires no special heating jacketing in storage tanks.
Chlorine-Free Formulation (<50 ppm): Meets stringent OEM specs (e.g., Cummins CES, Volvo VDS) and environmental standards (EcoLabel, Nordic Swan).
Excellent Soot Dispersancy Support: While not dispersant by design (unlike Lubrizol 7077 series), it does not interfere with succinimide dispersants, allowing formulators to maintain soot-handling capacity in heavy-duty diesel.

3. Automotive Axles (Limited)

While primarily industrial, some formulators use lower treat rates of 7067C to meet API GL-4 or GL-5 specifications for spiral bevel and hypoid axles. However, formulators must verify copper corrosion compatibility, as high treat rates can be aggressive to yellow metals (bronze, brass synchronizers).
