I searched this problem and didnt find anything so sorry if this has been posted...

I noticed sometimes when im in the car with the windows down I can smell something smoking, I get out and and can see smoke coming from under the car. It looks like there might be some oil (gear oil I assume) on the exhaust pipes. I just got the car not too long ago and the dealer said they serviced the car so Im thinking they may have got oil on the pipes in the process, but it seems pretty consistant. Ive had the car for about 2 months and if i drive it hard it smokes... any experiences with this?? any ideas?? hope this video helps...
