    That would be superfluous ..

    The SX model in place.


    side-by-side comparison


    I have not measured w/ a Micrometer the actual thread length though.

    I get the question, & the pictures don't really answer it. If the drain plug is removed, nothing blocks the flow out. That different than the valve not being removed.

    I can't imagine that doing this will result in more than a few drips being gained. I would not worry about it and enjoy my Fumoto valve.

    If you removed the Fumitomo valve completely...would more than an additional tablespoon of oil come out? I agree we may be over-thinking this...but it makes a great forum topic that could explode into 40 pages.

    Oh wait...someone already started a multi-page thread on this topic on bobistheoilguy website: huge Fumitomo thread

    BITOG would be the place where this could morph into a 20 page epic discussion for sure!

    Exactly! The valve itself may restrict the some oil from draining out. Thus, some crud could be left on the bottom of your oil pan. I added a Fumoto oil valve during my second oil change, & I have wondered the same thing since that time. I like the convenience of the valve, but I have thought about this. I even read some threads on the topic, too. It may vary with oil pans, however.

    I've thought about removing the valve and see what has been asked in thread. When I change my oil I have my front tires on about 4" blocks. I like using my mechanic creeper, & I need a little extra space to slide under the car. I feel the angle of my car may help the oil drain to the valve a little better & leave less in the engine oil pan.

    I think this is a legitimate question or concern. Removing the valve with every oil change eliminates the advantage of using it, however. It may be worth doing sometimes, however? Then again, it may be only a very small amount not worth worrying about, too?

    I always drive mine up on a 3 inch thick concrete block with the drain on the low side so even less would remain. I think it's not something to spend any time worrying about.

    Exactly. I drive up a 8 inch ramp.



    This is rudimentary drawing with my phone, but you get the idea. Plus the actual flow and suction of the oil draining would pull almost everything out at this angle, especially if the oil is warm at all.
