for the last 4 weeks ive noticed at night that every time i accelerate i get a lot of white and black smoke coming out of my exhaust. i put some forty diesel treatment in the tank but that has not helped also my fuel consumption has come down by about 6 mpg. My car is a renault laguna 2.0 dci 55 reg estate initiale
white smoke from ex,norm means too much oil in engine,it looks great as you accl ,but the cops will pull you.,check oil level,if need be,drain some out
