I have a 2009, 2 wheel drive F150 with 68,000 miles. My boss noticed today that there was blue smoke coming from my exhaust. I know that it means that my truck is burning oil. Is this something I need to be worried about and how is caused?

 

Is the smoke constant or just when you start it?

 

How much oil are you adding in between oil changes?

If it isn't much I would worry but you may want to change out your PCV and see if that makes any difference.
