I ran Red Line 75W-140 gear oil in my IRS for YEARS and YEARS with never an issue. I still run it to this day, even with my Torsen T2R differential...and still no problems. Just my .02.

use what the manufacture recommends, they engineered their part to run a certain type of fluid so i'd use it, plus its cheaper than synthetics.
