Q: Does this product contain a limited slip friction modifier

1 Answer
  • A: Hello, thank you for your question. It includes specialty anti‑scuffing additives and friction modifiers as part of its formulation to deliver enhanced protection and lubricity under extreme pressure conditions. However, it's important to clarify that these friction modifiers are not specifically formulated for limited-slip differentials. If you require oil for a limited-slip unit, consider using a product explicitly labeled as Limited Slip Gear Oil.
