Hello, to add oil to a peugeot 405 SRI engine you will find a dip stick located towards the front of the engine ( normally yellow in colour ) Underneath this dip stick should be a hole that it fits into. The cap with the hole in should unscrew providing you with somewhere to add oil. To check the oil level allow the oil to run down for a few minutes then replace the cap with the hole in it that the dipstick fits into, then push the dipstick into the hole and remove it fairly quickly and read off how much oil is in the engine. Note : the cap must be screwed fully down to obtain the correct oil level reading. If in dought please call into your local garage and ask the for a demonstration.
