Can someone tell me how much Oil I'll need to do an oil change

4.5l i think.

4.5 litres with the oil filter,no more no less

4.5L, Hmm odd that, thats what I thought it was supposed to be. Then shortly after new oil was in I suffered an oily boost solonoid and upon reading the threads it seems that the oil should only read halfway on the dipstick in order to eliminate this happening ?? So I take it 4L might be a good idea and then top up if you need it??
