A unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities. The viscosity characteristics allow the lubricant to resist throwoff and provide a film thickness greater than an SAE 250 grade, with the same low fluid friction as with our 80W140. Recommended for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes. Offers a "best of both worlds" balance of relatively low drag and the utmost in protection.
