Fumoto F-104

[Cummins2014]

Was involved in a discussion a while back on the amount of oil that drained out after pulling the Fumoto drain valve, after letting it drain. I thought it was significant, had never really measured it. Some were skeptical, some blew it off, etc ,etc. I said on that thread I would measure it on the next oil change.

Did the oil change today on my 2014 6.7 3500 Megacab . I use one of those 16 quart capacity pans, that can be taken to AutoZone or whoever to dispose of the oil . I let the Fumoto drain for about an half hour, down to a very slow drip. Let all the oil drain into the pan, cleaned up what hadn't drained in, put the cap on pan ,and pulled the Fumoto valve, and let it drain into the recessed part of the pan, about another half hour.

Took an 18 oz. disposable plastic cup ,and a funnel ,and started pouring the oil out of the pan that the Fumoto let drain AFTER being pulled, well it filled up the cup, made a bit of mess, overflowed onto an old towel I had under the cup. So I am going to guess after the initial 18 oz. which is just over a PINT of oil, that there was still at least another half cup, or 4 oz.

I am sure there is still skepticism, but over a pint of oil is too much for me, plus whatever doesn't drain. I will continue to pull the Fumoto after the initial drain, still nice to use ,and not have to get out of the way of the hot oil when using the OEM plug.

On the next oil change , I will do something a little different, I will let that Fumoto drain overnight. Want to see if it just takes a lot longer dripping all the oil out of there with the Fumoto. Its doubtful, but who knows .

On my last oil change I waited :15 after pulling the drain plug, removed the drain pan, and then put another catch container under the pan overnight. Drained an additional 10 ounces. 11 1/4 qts puts my oil level at the full mark after an extended drain, so I suspect about 3/4 of a quart stays in the engine if my dipstick is measuring accurately. I can see the benefit of using the Fumoto since the hot oil comes out like a fire hydrant with a standard plug, but also want every ounce of black oil possible to flow out during a change.

IMO , like you , I want all the old oil out I can get. The object here is to get as much of the oil out as possible. The Fumoto for me is not getting it done. As said on the next change I will let it drain all night, and then see what that valve leaves.

I had one of these on my ‘06 and yes, it was handy. But I did the same as you guys and took it out to drain the remaining oil. Well, I was not satisfied with the amount that came out. That plug never went back in. I just wear latex gloves when pulling the plug and the hot oil doesn’t burn as bad.

I’ve got one on my desk for the truck that I’ve just ordered already. I’m thinking of measuring the thickness of the flange on the pan and trimming the threaded portion down to match the flange. There’s lots of extra length on the one I have that is far from the valve ball.

Thats the only way that valve is going let all the oil out, if the threads are sticking above the flange its obvious it won't let all the oil out. I may do just that with mine. It seemed like the threads were the same length as original plug.

The way I figure it ,a plug has to be pulled regardless if you want all the oil to drain. Fumoto is just as easy to remove as the original plug, and a lot easier to get MOST of the oil out before removing, and not having to deal with that initial flood of oil coming out

I get chastised for adding 11 5/8 quarts since all the oil does NOT drain. I always let mine drain overnight. If I had a Fumoto I would pull it after the initial volume was drained.

I know we have been over this several times, we all do what we need to do. Just checked my oil after changing it yesterday, and putting a few miles on it. I showed maybe just a fraction over the full mark. Not enough for me to even think about not using all three gallons. I'm thinking if I had let it drip all night, which I have done, Its never been even a fraction over the full mark. This time it drained for an hour total, half hour Fumoto, half hour without.

These trucks with a 12 quart capacity plus or minus a half quart or possibly more, I can't imagine it hurting a thing. Sure there is a point where its too low or too much oil, but plus or minus a half quart , don't think anyone will find fault in that.

As far as the Fumoto, I have always pulled it after the initial drain, and down to just a slow drip. With your thinking you would only be able to put in 11 quarts if you had the fumoto, and didn't pull it.

Fumoto is just as easy to remove as the original plug,

But can you get a socket on it?
m going to start using a torque wrench.

There are reports of people overtightening. The oil pan is flimsy

Since you keep repeating this, how about a link documenting one legitimate report of a "flimsy" oil pan on an ISB

I see it flex when I install the plug. And I'm only putting what I estimate as about 40 ft lbs on the plug. But I replaced my old rusty (hurricane Irma) torque wrench just last week. So I will start using a torque wrench again.

It is thin steel. But I've changed alot of oil in my day, and It's the flimsiest one I've ever worked with.

Been tightening up oil plugs for a long time, not once have I ever used a torque wrench . This Ram is no exception . I snug them up like I always have. No I can't get a socket on it, I use a 3/4 end wrench.

That’s odd.....mine uses a 3/8ths inch ratchet.

I think it is a Fumoto thing...lol

I don't know about the new trucks but my '01 has several small drain passages across the grain of the pan threads to allow the oil to drain without pulling the plug all the way out.

Flimsy implies they don't hold up. Eg break/crack, etc. I've personally seen two rot out but one was on a 92 that was a plow truck for over 10 years and the other an 03 farm truck that is exposed to the elements 7 days a week. But for the most part, even around here they hold up quite well over the long term.

It is a Fumoto thing, but not a big deal to remove them.

There is no drain passages on the new ones, at least not my 2014. Thats sounds like a nice feature to have on the plug. One of the reasons that make the Fumoto nice to use, no big rush of oil when draining. Pulling that original plug with hot oil can be an adventure.

More sarcasm or what, hard to tell now .
