GD-401
Moly Treatment for Gear Oils
Includes Synthetic and GL-5 Hypoid
Applications

GD-401 Moly Treatment for Gear Oils is a multipurpose treatment for all grades of oils, including motorcycle final drives (hypoid GL-5). It may also be used as a treatment to standard transmissions, differentials, and other applications calling for gear oil. NOT RECOMMENDED WITH LIMITED SLIP DIFFERENTIALS AND WET CLUTCHES.

Benefits

GD-401 Moly Treatment for Gear Oils imparts the benefits of moly into plain gear oil.

GD-401 is a blend of moly and other chemicals. Moly is a solid film lubricant with a low coefficient of friction and an affinity for steel and other metals. The moly decreases friction of the two counter-moving sliding surfaces of gear teeth by filling in microscopic pores of the metal surfaces and plating out over the surface. Guard Dog lessens metal-to-metal contact to reduce friction and wear.

Typical Observations

GD-401 Moly Treatment for Gear Oils is a proprietary formula of molybdenum compounds plus other additives. The carrier is a 90 weight mineral oil. The flash point is greater than 399°F (ASTM* D 93 PMCC). The particle size range of the moly is 0.1 - 1.0 microns (median 0.8).

How To Use

Per 1 quart of oil, replace 4 oz. of plain oil with 4 oz. of Guard Dog. (The mixture ratio is 1:8. For example, 1 gallon of gear oil (8 pints) requires taking out 1 pint of oil and replacing it with 1 pint (16 oz.) of Guard Dog.)
