Default Fujimoto oil drain valve and oil change questions

I just did my first oil change on my Sti and am looking for ways to make it easier/ quicker. I've heard a lot about the Fujimoto oil drain valve but how much easier does this valve make oil changes? In terms of draining the oil, it only takes a couple of cranks of my socket wrench on the drain plug and the oil is draining. Does this valve really make oil changes better/ quicker?

Another question is my biggest issue with the oil change was the plastic shield on the underside of the car that covers the drain plug and oil filter. This thing was a PITA to get back on. I've heard that some people cut holes in the sheild to get easy access to the drain plug and oil filter so they dont have to take the sheild off for every oil chage. Is this wise to do or is the sheild there to add some level of protection.

Thanks,

Jay

The valve does make changes easier but double-check how far it dips below the oil pan. You may find that you have reduced ground clearance.

As far as the plastic shield is concerned you can easily and safely cut a flap in the plastic as long as the flap is facing towards the back of the car. Just cut a U shape with the fold facing the front bumper...that way if you do take a hit on the bottom it won't peel the flap open.

The Fumoto valves are definitely nice. On my 4x4 truck I have one with the hose nipple. Nice to be able to sit under the truck, put an old 1qt bottle under the valve, open the valve, fill the bottle, close, repeat until empty.

The only time I need to pull out the drain pan is when pulling the oil filter. Beginning to think that a nail in the filter housing to drain it will be nicer than the unscrew and spill method...

fumoto valves are awesome except that since they go in the place of the stock oil drain bolt, it makes the hole for oil to come out smaller..so it takes longer to drain your oil..

They sound like a great idea, but it scares me to know that my engine's life is relying on a small valve. What if something happened to the valve and it started draining oil going down the highway? At least with a drain plug, you know that sucker is on tight. I'd rather take the time and twist a ratchet a few times for the extra piece of mind.

nearly impossible for this to occur

the valve takes 2 motions to release it

you have to slide the lever over then up in order for the flow to begin

the location and this lever action
make it just about impossible for fluid to be released.

i have one on my RS. works very well

I'm with tayor04 on this. There is nothing safer than a 60 cents crush washer and a bolt. In addition; I WANT the oil to drain fast (flush) so remove as much of the bottom stuff as possible. The Fumoto valve MUST usually be modified in order to drain the all the Oil. There are directions posted on ScoobyMods on how to do the modification.

I've had a fumoto valve on my WRX for 3 years and never had any problems with leaks or anything. Makes changing my oil real easy and less messy.

With the fumotovalve I can change the oil in my wrx with no tools or ramps. All I need is a drain bucket. I like that added simplicity. Even though the original design is pretty much failsafe,I put a zip tie around mine just for added peace of mind.

LOL the Fumoto is on all my cars my only regret was buying the one with out nipple. With the nipple you can attach a hose and put it directly into a bottle.

The fumoto valve works great. Definitely makes oil changes a lot easier but like someone said it takes a little longer for the oil to drain out. But to me, that's no biggie.

I picked up a small worm screw clamp from Home Depot that fits perfectly over the part of the valve where the lever is. It's almost impossible to open the valve with the worm screw clamp on there. If I hit something hard enough to open the valve even with the clamp on there I'm sure I have bigger problems than an oil leak

The screw thingy on the worm clamp fits perfectly in the socket of my multi-bit screwdriver so it adds maybe 5 seconds to how long it takes the change the oil.

Probably overkill but the clamp cost like $0.80 for a pack of two. Cheap insurance...

its also nice because you can have the egine nice and hot when you drain your oil, and not hafta worry about touching hot oil thats spilling all over your hands when the drain bolt comes off. with the valve, you dont touch any hot oil, and thats a plus for me.

I've gotta vouch for the Fumoto goodness as well; I have them in all the cars now. I think I can say that this valve completes me in some way, my life is better thanks to this product.

I just did the first oil change in my STi. If I learned one thing, it's that when the car is jacked up high enough to get under it to get the shield off, it's too high to be letting the oil out into the usual drain pan. Next time I'll let it back down several inches so the oil doesn't splash.

One thing I can see the shield doing is keeping the underside of the engine from getting grimy. It would be so much easier to spray the shield with degreaser and hose it off when it's off the car.

Not in my experience with the Fumoto valve on my '05 STi. More oil is likely retained elsewhere throughout the engine versus the little bit that thr Fumoto valve may hold back from draining. A non-issue, IMHO. YMMV.

Did anyone have problems with opening their fumoto valve the first time out of the package? It took me nearly 20 minutes to get that POS open. What's up with that? I couldn't get the lever to turn. ANy hints?

Mine were tough to turn straight out of the package but I was able to do it with my hands. I opened and closed it a few dozen times. That seemed to loosen it up quite a bit.

You are pushing the lever down right before you attempt to turn it, right? Dumb question probably but that's all I can think of.

Yah, I'm pushing on the lever down before I turn it. I noticed it takes quite a bit of force to actually push it down because of its design.

I'll take a picture and post it in a little bit to show everyone else how difficult it is to exactly "push" the lever down.

I don't know if the 04 wrx and 05 sti have the same shield or not, but my shield had 2 big hooks that kinda hold it in place. Just push it up and slide it back, then throw a few of those clips in to secure it.

Yes I believe the 04 wrx has the same shield as the 05 sti. I did see those hooks but I was working without a ramp or jacks so it was hard to see completley under the car. I may try that next time.

Thanks for all the responses. I believe I may be getting a fujimoto valve soon.
