For those who like idea of Fumoto but don’t like the risk… try this!

Here’s some pics of my new Stahlbus drain valve. There’s no way for oil to leak from this unintentionally. Not only is the main valve a ball-check, there is a 2nd cap that’s sealed with o-ring. There is a small, 1/4 turn insert that’s attached to a chunk of hose to aid clean drains.

I’m actually thinking about attaching my vacuum extractor to the hose so I make sure I get a complete drain by being able to put the whole engine under vacuum 😎

The CleanOil is more than double the Stahlbus cost. The ValvoMax is close in cost but has a full thread to drain, whereas the Stahlbus is $46 and 1/4 turn. Like I said, I’ve used at least 3 Fumotos, and looking at all these designs, so far the Stahlbus is the simplest, safest, and easy to use drain I’ve found.

I already ordered one for the Transit Connect and will get one for my Impreza as soon as I find the right thread size. It should make changes on the Impreza about a 3-5 minute affair with no real mess!

There is a old, time proved system around here, wich is mainly used at farm equipment and hydraulic systems. But it is still very unknown and not popular with Car and Motorcycle owners here.



Works similar to the Stahlbus.

The stahlbus valve is also Aviailable in Stainless steel. ("Edelstahl" in german)

I saw that, they didn't have any in the US when I inquired about them a year or two ago and I wasn't about to go chasing one.
If the pan has been repaired especially aluminum pans and aftermarket pans which do not have very sold threads they are good thing.

I spent the cake for something like this for the 2.7 F150. The I/D for the drain hose was maybe 1/4”, which meant the I/D for the nipple inside the drain hose was even smaller. The flow rate was really slow, so I pulled it out, stuck it in a baggie and went back to the plastic yellow drain plug. their pan is such a unique design, most folks don’t make a solution for that vehicle.

The Fumoto is risky ? I had’t heard.

Where is the data on that ? All the ones I’ve installed are sill functioning OK several years later. Is there an expiration date on their reliability ?

Z, there are plenty of “safe” applications for Fumoto. I’m not saying anything bad against them; but say on a 7.3 Powerstroke, the valve is the lowest point on the truck. I’d never use one there… but the Stahlbus is a lower risk anywhere due to the ball-check and o-ringed cap. It requires the insert to open the ball-check and cannot be opened by road debris. That’s all…

$100 seems a bit high for what it is

While shopping oil drain valves, I came across Aeroquip sump drain valves for a Continental engine that was $409.00. Good thing the threads were 5/8-18 and wouldn't work any applications I have. There was another with 1-18 threads. This one was $1,264.00 :whistle:
