I find that whenever trying to change the oil after a nice long drive or even after 1 hour or 2 of cooling off, that damm bolt is way too hard to get off. Luckily I have a spare drain bolt, as I ended up deforming the nut. Even putting a hex key socket in the drain bolt and trying that way is not a easy task..... Just short of a Fumoto valve, I don't see this as a easy task at all. I've tried on 2 seperate occasions asking the US Fumoto sales guys which valve is the proper application, and both time, the have not responded to me. Not a good experiance via communication so I never picked one up.
