You are talking now about the engine oil, right?
This is very simple. although i never do it myself anymore. This is the only thing for which i take it in, since the shop where i buy it, changes it for free. No fuss of laying on the ground and getting rid of the old oil afterwards.
But in case you want to do it yourself, you will need the following;
1) Some recipient to catch the old oil. There are special recipients available for this, but it should have at least 7 lts capacity (6 lts coming out plus some space so that you can take it away without spilling)
2) There is a sealing ring under the drain plug. Sometimes it can be reused, but to prevent leaks i prefer to change it. Not sure about the size.

Best is to change the oil filter with every oil change. You will need a new filter and a spanner to remove the old filter. When you remove the old filter, some oil will come out, but the filter itself is full of oil, so take care. Installing the filter is just screwing it on until the seal touches the metal surface and fasten it 1 turn more (this can normally be done by hand), but first clean the sealing surface on the engine and put some fresh oil on the new filter seal.
4) Best is to change the oil when warm/hot, because then its thinner and will flow out more easily and take out most of the dirt as well. Only take care in not touching exhaust parts or other hot engine parts and use gloves to prevent burns. Wait with re-installing the drain plug until no more oil drips out.
5) After re-installing the drain plug, fill the engine with oil until the level has reached the full mark on the dipstick (on level ground). Now start the engine (after checking that all tools/rags etc are removed from the engine bay) and check that the low oil pressure light goes out within a few seconds. After running for a minute or so, switch the engine off and check for leaks at filter and drain plug. Wait a few minutes after switching the engine off (to allow the oil to drain back to the carter) and check the oil level again, since it will drop a bit due to filling of the oil filter, and fill until full mark.
Take care not to spill oil on the ground and donīt flush it through the gutter, but take it in for recycling.
