Hey guys, haven't posted in a while, so forgive my absenteeism due to school. I have a quick question with respects to a Toyota MR2 - MK1 - 4AGZE. My friend is up for an oil change, since from what I understood, the same oil has been in the SC for the past 15 years. Upon contacting toyota it seems that the price for SC oil is $50 USD for 30cc. I'd like to know if there are any substitutes available for this oil. Either by Red Line, RP, Amsoil, Mobil1, etc. Thanks guys. And it feels good to be back again.
