I have a 2001 V6 mustang that only has 32,000 miles onit. Since i have done some body work and what not it can sit in the garage sometimes. I have not driven it at all the past week or so but I decided to take it on a two hour trip. As i was on my way back and had to climb this big mountain on the interstate i looked in my rear view mirror and saw alot of smoke. I decided to get off at the next exit which was at the bottom of the mountain. But when i toped the mountain the smoke stopped and i never saw it anymore on the way home. I stopped at the next exit and checked the oil level which was a between add and full. My dad swears that it is because i am not driving it enough and that this is making the car burn oil. Is something wrong any suggestions......
