Doing a service yourself

Hi folks,



Wondered if anyone had a write up or there was a post for DIY servicing. I had a search but couldn't see a topic or sticky.



I know there's a lot of guides and check lists online.



I'm keen to do a service myself, maybe not too much in it, filters and an oil/coolant change?



It's maybe more general than model specific so apologies if this should be in a different forum area.



Also do you get your items from a dealer or use a local motor factor/online shop.



Finally how much oil and coolant/antifreeze would be needed for changes?



For info my car is a 2005 Megane II 1.5dCi 80



Thanks
