Oil Question
Gear Lube, Shockproof Heavy Gear Oil, 75W90, Limited Slip, Synthetic, 1 qt., Each
Reduce friction and prevent gear tooth breakage.
Red Line heavy ShockProof gear oil is a unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent. It provides a 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 throw-off and provide a film thickness similar to a 75W250 grade, while providing the same low fluid friction as an SAE 75W90. This gear oil is recommended for heavily loaded racing differentials and transmissions, off-road racing, and problem gearboxes.
But I have read on here dont use synthetic on the 9 inch. Should I send it back or continue to use it?
