They have got you brainwashed. you do not need 94.i actually put 94octane gas from Sunoco... trust me its better.... ull end up payin an extra 10$ for every 500KM... totally worth the money... plus u get better performance... and to be honest with u... if u leased it... u have 20K everyyear... hypothetically sayin that u have to fill up every 500KM, u need to fill up 40 times a year roughly... payin 10 dollers extra would be about $400 a year... im pretty sure, if u can afford a lexus... u can afford an extra $400!!!
honestly i have an audi a4 with major turbo upgrader, i can only put 94octane in it and i have to fill it up every 300KM... and the gas tank is bigger by like ~20 litter!!! so there it goes... im pretty screwed!!! lol
