why even use optimax?
I have noticed the exact same thing with my Type R. I am currently using Mobile 8000 but the exhause fumes are very strong especially in the morning. I didnt notice it much with Ultimate however i am still unsure of which fuels give me best performace vs milage. I am yet to try Vortex 98.
