Mga experts, is it normal kung nagbubuga ng itim na smoke ang turbo diesel car? Our's is a ford everest 2012. It happens usually at 2nd gear reaching about 2-2.5 rpm. Hatak mode po yun.. It's our first turbo charged car kasi.. Pasenya na po im newbie sa ganitong engine. Nasanay kasi ako sa biglang apak ng acceleration pedal sa civic fd ko pero i don't notice any black smoke(baka dahil unleaded). Hehe
