GD-420
Moly Treatment for SAE 80W-90 Gear Oil
Applications

GD-420 Moly Treatment for SAE 80W-90 Gear Oil is formulated for SAE 80W-90 automotive gear oil (GL-5 hypoid) and numerous other kinds of applications specifying an SAE 80W-90 gear oil. Not recommended for limited slip, positive traction, or locker type differential gear sets, or for gear oils used with wet clutches.

Benefits
GD-420 imparts the benefits* of moly into plain gear oil. 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, thus helping to keep the two surfaces separated during operation. Also, moly remains on the surface during stationary periods; this prevents "dry" starts (metal against metal) of the gear teeth when operation begins.

In vehicles with manual transmissions GD-420 improves shifting, reduces noise, helps to eliminate notchy, balky and irregular shifting.

Guard Dog protects the gears from wear, which extends the life of them.
