Fumoto vs Stahlbus drain valve

[Quickstep192]

After reading a recent oil change thread about people covered in hot oil, I’m thinking about a quick change valve.

The Fumoto looks very robust and seems to positive locking valve, but if the valve were ever compromised, there’s nothing to stop the oil from escaping.

The Stahlbus seems lighter, but has a cap, so if the valve were to fail, at least the cap provides some backup.

Any thoughts on this?

If it adds weight to the car, it's not going happen for me.

I've looked up Fumoto oil valve failures and they all revolve around 'oil pans' that are low, off road driving and something hitting the valve.
There is a safety clip on the valve and where our oil tank sits you'd have to be rock crawling for something to get up to that height.
I had one on my Lotus Elise and have had this one on my 911SC for about 5 years now.
You'd have to take the bottom of your motor off before something could engage it.

[Ok here we go]

I have had the Fumoto valve on my 3.2 oil tank for close to 4 years now, and on two of my other cars for close to 8 years. Unless something traumatic happens, you're not going to have a problem.

How much time does one of these devices save you? Somehow it seems like a low risk/reward ratio.

It is not so much the time as the mess it avoids....remove safety clip, pull spring loaded lever out of detent and up.
Straight steady stream of controlled oil exits, if you have a proper container no splash.
The oil stream is less than that of removing the bolt and more manageable....and when removing the bolt there is always a splash issue initially.
Just makes a messy job less of a mess.

After looking at both of them I opted for the Stahlbus. It seems much lower profile that the Fumoto and the valve is internal and looked less likely to be opened accidentally. It comes in two pieces. The plug with the internal valve and the second piece attaches to the plug with a section of hose for your pan. The valve only opens when the second piece is inserted and twisted. The down side being that you better not lose the second piece/hose combo or the thing is worthless.

I'll be installing it after I perform the first oil change either this weekend or next. I'll let you know how it goes.

The biggest thing is to be able to stick a rubber hose on the end, and guide the oil flow right into a 5 gallon container with ZERO splashing of oil from the torrent that comes out from the plug removal. It does save time, but most important to me, is no oil cleanup on the floor form the splashing of hot oil.

I now use a suction device to remove oil from my oil tank instead of removing the drain plug.

I use to do that...time consuming and a pita....and you still need to drain the block anyways.

I use the Eaton (Aeroquip) quick drain valve. Can't drain the oil with out the mating part that has a barbed fitting for a hose. Very low profile and very happy with it

From a grumpy old guy:

In the 20 years I have done oil changes on my 911 (and all the ones over my lifetime), I have never felt the need to one of these.

At about $30 each, I fail to see why I should not keep my $60 in my pocket for other things.

Exercise a bit of care and the factory plugs work fine.

Plus as these are valves, it is another potential (albeit very small) failure point. I like to minimize points of failure.

The conversation is never over until a grump old guy complains about 30 bucks.....on a Porsche.

For me, the pita is draining the oil tank into a large pan. The engine does not need such a large pan. With the race car and the front oil tank with 3 gallons of oil in it, I want avoid the pan method at all costs. The MightVac fluid vacuum tank is much easier....for me.

Interesting... I have one of those, but never thought to use it on the 911. Mine only holds about a gallon. Which one do you have?

I'm intrigued. Is this for the oil tank or for the sump? Which part did you get, and is there a specific model number?
