according to my manual u can. supposdly our cars have an "automatic knock sensor" or somethin like that. ur car will perform "worst" but it will not damage the engine (so it says). i would jus make sure to fill up with the lower grade octane once the tank is as empty as possible, im jus not comfertable with mixing gas.
