oil change

Hi, I have a 2017 204ps. What oil do I use? The manual says VW507 00 which is a 0w 30 oil but I also have a spare bottle of Mobil 1 fully synthetic 0W 40. T'internet says I can use both but the t'internet is occasionally habited by plums :-( Thoughts!

Now I've changed engine oil & filter in plenty of cars, but it's usually very easy to spot the oil filter location. Embarrassingly I'm struggling to find it(!). I've read the maintenance document available for download, found a pic on here on another thread, but I'm still looking. Can anyone...

Engine oil: Draining or extracting, renewing oil Filter and replenishing engine oil.

silly question , but I can’t Sean to find out what is the correct oil to put in the engine, could somebody please advise me as I need to put some in now?

I've just ticked over 11K and I'm going to be keeping it a while and don't fancy the idea of 20k oil changes so I'm going to do incremental changes my self. I've ordered the oil & filter but I'm not sure that I like the idea of removing the oil filter and covering the engine bay with oil once...
