So, curious, the dealership and the manual says to use 87 octane (research octane number 91) or higher. Kia sites, however, recommend premium unleaded. Does everyone just use premium or do they use 87?
I have a GT2Are you a 2.0 or gt owner?
Im personally a GT. I have used nothing but premium which is 91 here
