Is unbranded gas bad for your car?

Gas sold without a brand attached to it is called unbranded fuel in the industry. Unbranded does not have the additives in it that the branded fuels do. The gas must meet federal and state regulations, which means it has a set level of additives already in it, and is not bad for a consumer’s car.

87 is the standard octane rating that most car engines are designed for. The reason why you should never run a lower octane fuel on a vehicle tuned for higher octane fuel is because the tune has no way of detecting what fuel you are using and will continue to operate assuming you put in the correct fuel.
