Viperholics,
Is it O.K. to use Redline Synthetic 75W-90NS + Mopar Friction Modifier in a OEM 3.07 differential in a GTS? This is what a local expert (friend) recommended, but I just wanted to make sure - since it says 75W-140 + additive in the service manual. The manual states 41 ounces of fluid + 4 ounces of additive, which he concurred. Not to mention he gave me 2 pints for free....
Thanks in advance...
P.S. - Below is the product description from the Redline webpage. I believe the only difference between the 75w90NS and the 75w90 is the later already has the friction modifier additive.
PRODUCT APPLICATION
75W90 NS- a GL-5 which does not contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing limited-slip differentials where weak spring design causes too much wheel spin.
75W90 Gear Oil - the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization. Exceeds API GL-5.
