a-o-a friends,
i am using caltex havilen oil 20W/50 . and i normaly change that after 3000 kms. but now a days it goes very black after the 3000 milage, where as the oil level remains the same.... that made me think to change the engine oil. my office drivers suggested me to use toyota oil or liquimoli.
friends please help me out
Regards,
Asfand yar
