I run one on my 2003 and my wife's 2000. So that's both 6th & 7th gen. Also have one on my pop's 1999 Civic and my 2008 Chrysler Aspen. So I highly recommend the use of Fumoto drains. I advise going with the ones with the nipple and if Fumoto's web site recommends using the spacer adapter, you should get it as well. Will save you the hassle of stripped out plug/oil pan and the need to replace crush washers. Part of the reason I got one on my pop's Civic so fast. He stripped out the pan and we had to replace it. Plus you won't need any tools unless your filter is difficult to remove. I have had zero problems with any of them. If you are worried about the valve getting accidentally opened, they offer a safety clip. Although again, I've never had an issue.
They do drain slower than just removing a plug. This is especially more relevant when the oil is cold. Some recommend warming the engine up first to help the flow. However, in my opinion this throws the oil back up in the engine which will require more time for it to fall back down in the pan to drain so I just do it cold. When I do an oil change, I typically open the valve first, replace the filter while it drains (like most do), then take a 10 minute break while I let it drain as much as possible. Come back later, close valve and add oil. Makes things so much easier.
