Thanks had a better look today and I can see an abvious fill point on the front side, looks like about 24mm but is a flat tapped bolt unlike the one in your picture with the hole in it. Also found drain plug as described. Also found what is a 12-13mm bolt with washer on its own at about same level as fill point also towards front but a bit more underneath and more towards the wheel side. Any idea what this is for? As for oil change, looks like it has never been done and cars done about 170 000km. Like I said the service schedule mentions nothing about changing it. No sign of leaks but sounds like a good idea to change it and make sure the level is right. Yes its just my daily commute but quickly got rid of the crappy tyres (never heard of the brand) and but on some Toyo Neo +, great in greasy conditions, good price and much quieter.
