Red Line 58504 75W90 Full Synthetic Superlight Shockproof Gear Oil - 1 Quart

Redline Synthetic Shockproof Gear Oil provides unequaled protection for high-performance differentials and transmissions that are heavily loaded, or which see shock loading. This revolutionary lubricant is completely different from conventional lubricant technology in several ways. The viscosity characteristics are significantly improved. Gear teeth need high viscosity at high temperatures to prevent metal-to-metal contact and low viscosity when cold to reduce fluid friction. The shockproof chemistry significantly reduces the thinning effect of high temperatures. The Heavy can be rated as a 75W250 Gear Oil but has the lower internal fluid friction of an SAE 75W90.
