I talked to my mechanic since I bought my diesel an he and his co-worker have said no smoke is good smoke, I'm still new to the diesel an have wondered why do you want your truck to smoke?

my truck kinda throws a light grey haze not the pitch black coal rollin smoke, smoke is unburnt fuel, so in my opinion its just less unburnt fuel not really a bad thing, thats just my opinion tho
