Remove the oil fill cap and dipstick.
Remove drain plug.
Remove oil filter, be sure old gasket removes with filter.
Replace oil filter making sure to lube the rubber gasket with oil (new or old, doesn't matter...this oil won't enter into the system, it's just there to ease of the final tightening of the filter).
Replace drain plug, be sure to use a new crush washer.
Use some brake cleaner to clean up any oil that has dripped onto anything.
Fill up with new oil, but stop short about .5 QT low.
Start up the engine and let it run for a few moments.
Check the oil level on the dip stick.
Finish filling up.
Restart motor, run for a few moments, shut down.
Recheck oil level, top off if needed.
Also, check your tire pressures, wear pattern (rotate them as well, if you can), your brakes, your drive/accessory belts, power steering fluid level and condition, brake fluid level (don't open the resivoir unless you are putting fluid in), coolant level (in both the radiator and reserve....NEVER open the radiator cap when hot), washer fluid level, and ATF level and condition (while running), and generally just inspect the vehicle overall for wear, tear and anything unusual. Get in the habit of doing ALL of this eith every oil change, you'll more then likely find something that needs attention that otherwise you would've never noticed.
