Depending on how i'm feeling, i like to drive around with my spoiler up all the time. Sometimes i even leave it up when i park. Is there anything i should be aware of leaving my spoiler up overnight, or for an extended period of time. Any problems with the hinges and gear? How about gas mileage, i know it adds some down-force, but was wondering how it actually affects the gas mileage at low and high speeds, i always have it up at high speeds, but wondering if its hurting to have it up at lower speeds too.
