Hi there,
This is Shehryar. I have NP y60 - TD42 (1991). The engine is burning oil. I use to put 9 litres oil in it and after 4000KM, while changing, almost 7 litres oil is burnt and its producing a dense blackish smoke too.
Expert opinion is required please. What should be the suitable treatment?
Regards,
Shehryar
