yup it's just the name, you need to check the octane. Here supreme is usually 93, unless you go to wawa then it's 92, or if you go to sunoco it's 91 and ultra is 93. I've gotten in the habbit if asking for the octane I want, so if I go to another station I don't accidently ask for premium and its actually what they call their midgrade. I just ask for fill it with 93.
