I've changed my own automotive motor oil for nearly 50 years. Recently I added the newer version of the Fumoto valve to my new Sienna van at the first oil change. I thought it was great at first, as it made it easier to perform regular oil drains with less mess, with no chance of misplacing the drain plug, and no need to replace a $2 fiber washer. Also, I could make small adjustments to oil level, which is useful when trying to determine the exact volume of oil to hit dipstick "full mark" perfectly (manufacturer specs are sometimes not precise or correct). On the next oil change I discovered the Fumoto valve threads extend into the oil pan ~3-4 mm, causing a small amount of used oil to be retained in the oil pan after a complete drain. Surprisingly this small volume of oil caused the other ~4 qts of new oil to look brown immediately after the oil change. Thus my ~95% new oil looked like oil with 5K miles usage! Due to this unwanted (and confusing) appearance, plus the chance of unwanted metal particles being retained in the small pool of undrained used oil in the pan, I reluctantly removed the Fumoto valve. I considered making a 3mm deep hacksaw cut across the diameter of the Fumoto valve inlet to increase drainage of the used oil, but decided it might cause a weakness resulting in a broken threaded section stuck in my oil pan, so I decided to not dig this hole any deeper. I suspect the extent of this "Fumoto brown new oil problem" varies according to vehicle type to some degree, but it was a real disappointment in the Toyota Sienna. I hope this information helps save someone $35 for a fancy drain plug that has to be discarded after 5K miles.
Thanks for taking the time to share this information, very much appreciated! I’m sure it will help someone out! I did make a video where I measured how much oil remains, trapped in the pan compared to the regular oil plug. I personally found it to be pretty negligible. But, it does indeed trap some used oil.
@@HowtoandReviewsOfficial TY! I watched it just now (very thorough test w/ good presentation of results, btw), thinking it may have been one of several YT videos I watched a year ago before I bought the Fumoto F-133 for 23 Sienna. I agree that ~2% retention is minor, & that metal particles unlikely. In my case I did not measure retention volume, as my main concern was the troubling brownish color of the new oil on the dipstick (this does make it much easier to read as new oil is transparent). I am reconsidering Fumoto based on your 2% data. Thanks again, great content, subscribed!
Hello, how are you doing there so I can say you making great videos in a possible chance that you can do a video on how to bleed the brakes after changing the brakes
How does the drain time differ between using the Fumoto valve vs. the standard drain bolt? I've heard people complain the valve takes a lot longer. Thanks.
I’ve been using these for several years now and I don’t remember exactly how long the standard drain plug takes. But, these do take longer. The internal flow diameter is smaller than the drain plug hole diameter.

@@HowtoandReviewsOfficialI think you should do a comparison of how long it takes with the standard drain plug compared to the fumoto valves.
