Nothing! Nothing at all. Seriously. I park the car on level ground. Turn the wheels full lock right. Lay on the ground next to the right side of the car, head near the front and feet down by the doors, with my arm directly in front of the wheel. I reach in with my arm and twist off the filter. If you look at the link I posted above, the vantage point of the camera is about where I'm positioned on the floor as I'm doing all this. The engineers at Honda were smart enough to place the filter and oil pan drain plug at a location that's easy to get to without having to raise the car up off the ground. The only real obstacle is buying an oil drain pan low enough to fit under the car.
But, if you have a jack and that works for you, that's more than okay. I wasn't picking on you seriously. Just a little teasin'.
In fact, using a floor jack makes it easier and more accessible. But it's not necessary to get the job done, like in most other cars. Hell, you should have seen my old truck. You had to lift the vehicle up off the ground (I used the drive up ramps, as I don't get under a car with just a floorjack. I'd at least use jackstands). Crawl totally under the truck. Reach *UP* into the engine compartment. Not touch the freakin' hot exhaust manifold. Slip your hand through a small opening between components. Try to grab onto the oil filter and get a good enough grip on it to turn it. Then as the hot oil starts to run down your arm, try to pull your hand out of that tight opening and in the process burn yourself on the exhast manifold...
Not to mention, oil splattered everywhere. Did I mention, I really like the design on the Accord!
