I need to change mine pretty soon, maybe I will take some extra time and make a DIY vid.
But as others have said, don't be scared...
make sure the engine is somewhat warm, open up the filter housing and remove the existing filter. then remove the leftover oil inside the housing. next, insert the new filter and replace the 2 gaskets of the filter housing.
after that all you have to do is drain the oil out from the two drain plugs, put the plugs back in, and refill with oil! Make sure you put slightly less than the full amount...take it for a drive and allow the engine to warm up so that the oil level may be displayed. Add oil accordingly to bring the level up to full. Make sure you don't overfill though, add a small amount at a time.
