Hi guys Can someone give me some tips here or am I just missing something. I changed my engine oil on Saturday as per the excellent detailed instructions here in the forum. Everything went very smoothly until today when I checked the level to find that there was only a small amount showing on the dipstick, the oil was topped up with 4.2 litres as per the requirement for change with filter. Am I missing something here ? Do I need to top it up to the required mark or is there something else I should have done.??
