I have recently changed the engine oil of my car, but it becomes black within a week. Also, my car gives out black smoke. Why is this so ?

Best stay in your original post-there's no fast fix here-its probably your cylinders are washed-up-gas going thru the rings like crazy and diluting the oil-I've told you earlier your A/F mix too rich-meaning its burning more fuel than air-Check what I've suggested-do not comeback to this post-TY
