Fumoto drain valve once installed, extends into the oil pan so that it is not flush and could allow for build up of unwanted particles inside the pan. The oil drain speed is restricted, and a fair amount of oil can’t be drained out completely.Fumoto valve FTW. Google it.
Above is a very informative link about Fumoto drain valve although this "Mythbusters: Fumoto Engine Oil Drain Valve" is for a 2008 Subaru Impreza WRX STi:
NateCal said:Myth #1- The Fumoto Engine Oil Drain Valve, once installed, extends into the oil pan so that it is not flush and could allow for build up of unwanted particles inside the pan.
So as far as Myth #1 goes, it is:
The Fumoto valve extends aprox 1/8" to 3/16" into the oil pan.
Myth #2- Due to Myth #1, metal shavings and other particles will remain in the oil pan when using the Fumoto Oil Drain Valve to change your engine oil.
NateCal said:To me, that says the 1/8" to 3/16" of the valve extended inside the pan is NOT stopping the oil from bringing all the crap out with it when it is draining.
However, I cleaned my oil pan again, and planned to remove the Fumoto valve and flush a full quart of fresh oil through just to see what else would come out without the valve installed.
When I removed the valve I was kinda of shocked by the amount of oil that was still in the oil pan. There was probably a good 10 second stream of oil that came out once the valve was removed.
Then I ran the full quart of fresh oil through (without the valve installed). I then repeated the process of carefully dumping the oil, leaving the crap behind, to examine the oil pan. And the was NOTHING. The pan was clean as a whistle. Everything came out when I initially drained the oil using the valve. Even with the little oil that was trapped in the pan by the Fumoto valve.

Q. Does my Engine Oil Drain Valve protrude into the interior of the oil pan and prevent full drainage of my engine oil?
A. No. The threaded oil drain plug hole is always reinforced to accept the threaded bolt of the drain plug. In most cases, the Engine Oil Drain Valve will not extend past this threaded portion of the drain hole and will allow the oil to be properly drained. Your Engine Oil Drain Valve will let you drain your engine oil while it is hot without burning your hands and it is much more effective than trying to pump the oil out from above.
Your dealer did the right thing. Your CX-5 equipped with a “dynamic” and real-time oil change reminder right in your dash, and hopefully the oil change schedule in maintenance monitor has been reset to 7,500 miles or 100% oil life remaining with Flexible OCI.Took her for an oil change. Got to take care of my girl. I was a little less than impressed with the dealership though. For $100 oil change ya think they would have thrown up that little courtesy reminder sticker..nope. Sigh. Can’t get good service these days it seems.

That dealership does not have service coupons?
