    My Dad started using Fumoto valves back when dinosaurs roamed the Earth....or something like that.

    I still have a 1987 Corolla, which mostly serves as a Mouse playpen, that has a Fumoto installed. My Prius and Kevin's Camry both have Fumotos.

    My dad's Camry as well as his Nissan Mini-Van, as well as several other rigs he has owed have Fumotos.

    No problem -- except -- you got me....NOW! :(

    I've got a couple of weeks off work. And for some reason am doing nothing but hanging about the home, taking the dog to the river and generally getting into trouble. To make it worse, hubby is gone on a biz trip (he returns tonight :rockon:)....so I decided to be somewhat productive and change oil in my Prius.

    Then I decided to work on the Corolla. Drove it down my 500-yard steep driveway....drove it down to the mule farm....said hi to the mules and drove back. Got out, looked under and I had Niagra Falls.....oil spewing out of the Fumoto. The valve was half-open.

    I quickly shut it off, pushed the car back and poured on the Jonny Cat.

    Checked the dipstick, down about 8-10 ounces. I DID NOT hit anything on the warm-up drive. There was nothing under the car. I checked the area where the car had been sitting and no oil.

    Any ideas? Sure, I didn't lose much oil...and this valve has been on this car for at least 12 or 13 years, I think....but how did it open?

    Maybe those mice are out for revenge? Anyone else have any Fumoto problems?

    PS -- I should add, now that I think about it.....Dear hubby had been washing HIS car a week or so ago...Of course, he didn't touch my Prius or Corolla, but he did leave a balled up section of hose in front of said Corolla. It may be possible that he got the hose jammed under and yanked it out, but it still seems odd, with the way the valve works, that he could have somehow got it open....and that ---it appears -- no oil left until I drove it --...of course it is parked on a sort of "mud pan," so unless I actually tasted the mud.....

    Absolutely zero issues with our two (his 2004, hers 2005). Highly recommend. Make sure the lever-arm rests in the "notch" that forces u to lift it up and over in order to rotate for open.

    Google fumoto fail, also fumoto leak.

    They do occasionally leak. I will find someplace else to reduce my labor other than trusting a single small spring to hold the oil in my engine.

    I've got to squeal out to PDX (portland airport) in a few minutes :(

    But, I did a quick google search and I keep reading about people who recommend "wiring" the valve shut, just in case....first, wouldn't that defeat the "ease" factor.

    Second, I can't "picture" in my mind how you would "wire it."

    Finally, reading back some of my postings, it sounds as if Kevin is continually on my bad side. One or two of you may remember, I was a virginal Prius owner...three weeks into my love affair with my brand-new Prius when I went on a business trip to San Diego.

    My parting words to the love of my life were, "Don't drive my new car."

    I returned four days later to find a broken headlight and a smashed front-end on my poor Prius. Knucklehead had driven it to Drainbow Town (Eugene, Ore.) and had a "mishap."

    So, while we get along mostly, there is a "sore spot" where cars are concerned :focus:

    Just play it cool, and pretend you know what everybody's talking about. In the time you posted, you could have looked it up...:D

    He's still alive? AND you're just off to pick him up at the airport? Oy.

    Here's a post from me in 2006 regarding this subject. Since then I've purchased another car and put a Fumoto valve on it.

    "The Prius is the fifth car that I've used a Fumoto valve on. That being said it is possible to have one opened on the road. The first car I used one of these on was an 83 Saab. Keep in mind that on the Saab the valve hung a little lower than on all my other cars. Very early one morning (no traffic) I was driving on the freeway and a smallish cardboard box (about 6"x6"x6") blew from the side of the road directly under my car. I Heard it hit the car and then looked in my rearview mirror and saw that it wasn't stuck underneath. About 15 seconds later the red oil light came on, I "knew" that the oil level was fine because I had checked it a few days earlier. Like an idiot I kept driving for another 1/2-1 minute. Then the car started sounding funny and the temp started spiking, so I popped it into neutral killed the engine and coasted down the offramp that was luckily close by. After coming to a stop I opened the hood and pulled the dipstick. Seeing smoke come out of the dipstick tube is never a good sign. When I stuck my head underneath the car I saw that the valve was wide open. My theory is that the box got caught on the lever and was able to slide it past the detent and then swing it open. Even though this happened I chalked it up to a freak event and am still an avid proponent of these valves.

    If you're wondering about the car. I closed the valve and filled the engine back up with oil. When I cranked it over to start it made the most horrible scraping/grinding noise I've ever heard. A noise that you never want to hear on mechanical components. But then the engine kicked over, the noise went away and it ran fine. After that incident I put another 50k plus miles on the car. It finally died with a major front suspension failure at 230k miles. All those miles were on the original engine and original turbo."

    I've been using one for perhaps four years with no problems. I'm certainly not disputing you, but I really don't see how it could open from getting snagged on something on the road unless it also gets damaged. Sometimes I have a devil of a time opening it when I want it open.

    Actually, that Fumoto valve was on my now totalled 2006. I got it from the guy in Indiana that supplies them with Stainless Steel Snap Rings. The ring fits into the groove, keeping the valve operator from moving.

    I lubed mine up with Petroleum jelly after each oil change to avoid any bimetalic corrosion.

    Been using it for over 4 years and love it. The drain is slower but worth the benefit.

    I installed one on our 2007 Prius six months ago. Fumoto recommends a hose clamp for off-road and agricultural use. While our Prius will probably never see an unpaved road, I added a stainless steel hose clamp as insurance. After reading this forum, I'm glad I did!

    The only downside I see with the Fumoto is that it takes longer for the oil to drain. I open the valve when I start and do all of the other checks and change the filter while it drains.

    Hi pschat friends,
    I've started using the Fumoto valves since 1988. My 98 Camry V6, 99 Protege, 2003 Dodge Neon SRX bought at 2005 and my present 2005 Black Gen 2 ,package #6 bought at 2008 all using the Fumoto valve. Wonderful product. Never have any leaking or 'open' happening. It's reliable and easy to install and use. Just the opening a bit small makes the draining take longer time. That's no big deal. Garage floor was clean and without a single drop of oil.

    I had the same problem with a Fumoto accidently opening a few years ago. I had driven on a gravel road, and then the next morning discovered I had no oil in my engine. The valve was open just the slightest amount, and had slowly dripped all the oil out over night. I can only assume a stray rock had hit the valve just right and opened it. Never had another incident since then, and have driven on gravel roads since, but not often. Other than that incident, I think the Fumoto is the greatest.

    I had a Fumoto on my '06 Civic Hybrid. No issues whatsoever. I liked being able to drain the oil hot. My wife's '06 Highlander Hybrid has one as well. Never an issue. I am going to order one for the '10 Prius.

    I added a zip tie across the lever just to keep the lever in place. When I do a oil change I cut off the zip tie and after draining all the oil out, I install another zip tie.

    Changing the oil as I speak on my Prius. Have had a Fumoto on the Prius since I picked it up new from the dealer some 10 years ago. Nary a problem.

    Maybe my old Corolla was just an odd fluke. Have had no problems with our Camry, which has had a Fumoto since for 14 years.

    No problems with Fumoto valves on both vehicles (2010 Camry / 2011 Prius).
