Whether you're racing on the open road or stuck in traffic downtown, you expect your car to perform when you put your foot on the gas pedal. If you think your car's performance relies on its manufacturer and your maintaining the vehicle, you're right. But it also depends on the quality of gasoline you put in it. If you put a lower-quality gasoline, with a less effective additive, you could pay the price.
Your engine could have trouble starting when cold, might warm up slowly, and might not run smoothly under some conditions.
You might not receive the power you expect.
Over time, fuel economy could suffer, and your car could generate more emissions into the atmosphere. Your choice of gasoline could add to engine deposits on critical engine parts.
