There are a number of 2.5L "diy's" out there; I'm pretty sure, they are similar over the years. The main difference; to most cars, is the oil filter housing is plastic and the replaceable filter element, is inside.
Should be fairly straight forward. Just make sure you crack open the oil filter housing a little before draining the oil. It should help get a little more out that way. Be sure to change the copper crush washer as well, unless of course you're using a vacuum to suck the oil out, then it doesn't matter.
Turns out changing the oil is easier than I thought. Tools needed - 19mm socket, torx driver, 74.5mm oil wrench and a 3/8 socket wrench, jack stands and something to drain the oil into. Jack up the car and rest it on the Jack stands. Remove the gravel guard with the appropriate torx driver. Place the oil catch below the drain plug, using a 19mm socket remove the drain plug. Drain the oil into what ever you use to catch the waste oil. Replace the plug. Remove the oil filter housing with the 74.5 mm oil wrench. Replace the filter in side filter housing. Replace the oil filter housing and hand tighten. Replace the gravel guard and lower the vehicle. Now fill the engine e with 5qts 5w30 oil.
