Redline 75W90 differential gear oil (NA/NB/NC)

Redline synthetic gear oil. Perfect for all stock Miata differentials, including all types of factory limited slips as well as aftermarket clutch-style limited slips. Slightly thicker than the stock ND diff fluid, which should give better protection under hard use.

Works well in all Miata differentials from standard to viscous (90-93) to Torsen limited slips (94+). One quart required. Not for use in the transmission, use either MTL or MT-90 there.
