You will need to start with locating the drain plug on the bottom of the oil pan
Once you find the drain plug get a ratchet and loosen the drain plug
Until it the oil starts to come out
Than put a drain pan under it to catch the oil ...

Take a break and go get something to eat or drink
or you can take a nap while the oil drains
Come back in like fifteen minutes
Once the oil stops draining pull the drain plug out ...

Now you need to locate the oil filter
Once you find the oil filter take it off and put the new one on
Make sure the oil seal is on the oil filter
If it is not you won't have a good seal and it will leak
Put the drain plug back in and then put the oil in the oil fill
Now you are done.
