Question about 2005 Peugeot 405
No harm provided this is the grade you added to. Not a lot of harm if previous oil was syntectic or semi synthetic but if the oil in the engine was mineral oil then they won't mix properly. If you are unsure then it's best to change it all. Another thought I have is if it needed topping up then it's probably ready for an oil change anyway. If you have changed it recently check it was changed with the recomended grade. If you put synthetic oil in an engine where mineral or semi syntectic is recomended then fully synthetic your engine may burn it as it is very thin. Hope all this makes sence to you if not get back to me and I will clarify. Cheer's
