The frs/brz has a 6 month or 7.5 month interval (depending on the year), the recommended oil is 0w20. It doesn't matter if it's standard/non synthetic for 6 months because 0w20 does not come in non-Synthetic.
Bottom line is it's a 6 month or 7.5 month oil change with synthetic because 0w20 only comes in Synthetic. I believe the 13-14 is 7.5 months per the manual and 15+ is 6 months.
