Bardahl No-Smoke oil additive . I use this product for awhile now.. The Lincoln Towncar has been smoking ,since I did the 1st oil change.. It had a service sticker with 10w30 written on it so I guess that was being used in the engine of the 4.6 Ford.. So it did smoke over hours of driving, and at stops and idle. Bardahl No-Smoke oil additive stopped the smoke so my passengers do not get see the smoke , in or when leaving the car( it does work ) for me it may for you depending how bad your smoke issue is..
