Hi I got my mitsubishi space star in the this May, it is a good car. Nothing wrong in its drive or road comforts. It is a 1.9 DI –D diesel engine driven car. Actually it is my first diesel car… the thing that makes me feel worried…………. after a mileage of 2000 miles I got changed its engine oil it looks more black than the other petrole cars I have been using before. Is it a common thing with the deisel engines. I am here to know the answer. Allison
