2013-2016:
Use either of the following:
• “MG Gear Oil special II”
• Other gear oil that meets API GL-3 or
upper grade and SAE 75W-90 specifications
2017-2018:
Use either of the following:
• “MG Gear Oil special II”
• Other gear oil that meets API GL-3, GL4,
or GL-5 and SAE 75W-90 specifications
*Edit: The Toyota manual for the 2018 86 still says "recommended oil grade is API GL-3. However, API GL-4 can also be used"

GL5 is used in the differential. GL3/4 is fine in the transmission.
