I installed the Fumoto valve, (that has a nipple on it for the clear drain hose that came with it) when I did my break in oil change at about 1300 miles.
In a few days, I will do the 5,000 mile oil change, before I take Miss Daisy back to the dealer for the 5,000 mile service. The 5,000 mile service at the dealer does NOT include an oil change.
At that time, I will check with the service writer how they feel about the Fumoto oil valve. If they refuse to work on Miss Daisy for the 10,000 mile service/oil change, because of the Fumoto valve, I will find another dealer, or simply not let them change the oil.. No big deal.
