Red Line 75W90NS  GL-5 Gear Oil Quart

Red Line® engine and transmission lubricants have long been the choice of racers and knowledgeable engine builders. 

Helping slow synchros for easier shifting across a broad temperature range, Red Line 75W90NS Gear Oil is popular in Ferrari, Porsche and Subaru transaxles and also in muscle car applications like Ford Top Loader, Borg-Warner T-10 and Super T-10, and Muncie transmissions.

The thermal stability, film strength and reduced parasitic drag found in Red Line® engine oil all contribute to lower operating temperatures, increased engine life and more power. Red Lines’® racing heritage is reflected in all of their products...you’ll see more Red Line® products at the track than any other lubricant manufacturer for all of these reasons.
