The differential gear oil used in Toyota 4Runner and FJ Cruiser vehicles has been changed to a 75W-85 GL5 synthetic gear oil beginning with the 2008 model year.

This new synthetic gear oil is compatible with 2003-2007 4Runner and 2007 FJ Cruiser differentials. Note that Toyota lists different gear oils for LSD and non-LSD differentials.
