I already changed my oil and filter at 1,000 miles. I put the car up on my ramps. Drain the oil pan with the drain plug. Next, the filter housing is on the passenger side of the oil pan, you can't miss it. I use one of those oil filter wrenches that attaches to a 3/8" drive ratchet...the wrench I use is the type that expands with 2 ears on it on opposite sides, and its got a spring that holds a slight pressure on the ears to keep them together. You can buy one of these oil filter wrenches at AutoZone for a few bucks, and they fit a number of different sized filters, ( I like the way it works). Anyhow, the filter housing unscrews counter clockwise. Just put an oil pan underneath to catch the little bit of oil that leaks out. Pull the filter element out of the cartridge housing. Put the new filter element into the housing, remove the old O-ring on the filter housing, replace the O-ring on the filter element housing that is provided with the "new" filter element. It's always a good idea to lightly coat that new O-ring with motor oil before putting it on the housing...providing a better seal. Then with the new O-ring and filter element installed in the filter housing, just screw it on clockwise, (make sure that you don't cross-thread it). And of course, don't forget to put oil back into the engine. Start the car, check for leaks...always a good idea after changing oil, and you're all finished. It's really not much different than the old style screw-on type filters. The best filter I know is the OEM Toyota filter. They are about $4 a piece. On a difficulty scale of 1 -10, I would declare this a (1.5). (1) being a regular screw-on type filter, and (1.5) for the cartridge type filter on the Xd. Don't stress out, it's a piece of cake. The entire filter change shouldn't take more than about 10 minutes. Just take your time, no big deal.
