my car uses 2.5 qts of oil every 5,000 miles. I can not drive any further without adding or changing the oil as the car will begin misfiring, etc. The car is in great shape and I have no signs that it is buring oil... Is this normal or is something else wrong?

thanks for the note... the tailpipe is not covered with abnormal amounts... I will check the plugs to see if anything is looking poorly.
