    I wasn't paying attention the pump didn't pump too much just .6 gallons but I stopped asap and filled the rest up with 18 gallons of 93 it was close to empty. Will I be fine. And just out of curiosity what happens if you do fill up your car with 87 regular gas. ?

    To answer what happens: I'm certainly no expert, but the car will adjust the timing and fuel injection for the lower octane fuel. End result will just be less power and lower fuel economy for that particular tank of gas. Tl;dr as the above posters said, you'll be fine.

    In the USA we actually have pretty low grade gas. In other parts of the world the gas would be equivalent to 98 octane if in the US.

    I have actually seen people mixing 87(Regular) and 93 octane(Premium)... At Shell... In an Audi....

    .6 Gallons on a full tank of Premium, you wont notice anything.
