i take a bottle of oil, tilt the tool upside down, and put a few drops in it.

I don't see why it wouldn't work.

Consider a tool such as an impact wrench. Most of those are rated for avg consumption of 5-7 scfm @ 90. Average is generally assuming 25% duty cycle, so while the tool is actually running it's consuming 20-32 scfm, all moving through that 3/8" hose. If your concern is the oil falling out of the air, reconsider the velocity with which that air must be moving to get that much air through that small of a hose. I'd need measurements of the actual pressure and flow during operation to calculate that velocity, but off the top of my head, I would imagine it in the hundreds of feet per second. Sufficient to carry a meaningful quantity of oil along with it.

That said, if I had an automatic oiler, I'd still oil my tools manually also. Mine get oiled before they get put away at the end of the day. That way, if they've gotten wet during use, at least they are put away freshly oiled to avoid corrosion.

I read an article a while back on shop air plumbing. It actually recommended manual tool oiling even with an automatic oiler. The comment they made, was that the purpose of the air line oiler, was not to oil the air tools, but the air LINES, which makes sense if your air distribution lines are black iron pipe.

What also may make the difference is where the oiler is installed. At the compressor, prior to the distribution lines, I think would get less oil out to the air tool than an oiler installed at the point where the individual air hose begins.

Those in line oilers are used heavily in industry. They are placed at the work station with a short hose to the tool. The amount of oil dispensed can be adjusted for the tool being used. They are a great way to extend the life of pneumatic tools requiring regular oiling since they oil the tool every time the tool is activated.

You are correct that it would not be very useful in front of a 100 ft hose. One other thing to remember is any hose that has been used with an oiler should never be used for spray painting.

For home/hobby tools a simple drop or two of pneumatic tool oil before you use the tool for the day is sufficient. An alternative for heavily used tools are the mini in line oilers like this one:

They aren't adjustable and tend to dispense too much oil in my experience.

I like the idea of an in-line oiler but . . . my concern is that the oiler isn't working right and the tool might run dry.

I've got some old Campbell air tools. Might be 20+ years old. I don't use them daily but when I do use them, I usually start with a drop or two of oil (I've used everything from 3 in 1 to specfic air tool oil). I've never had a problem. I finish up with a drop or two of oil and then hook the air hose back on and give the tool a spin so the oil is spread around. Sometimes my air tools have set up for a year w/o use and they all still work fine. I've got a 3/8 side ratchet, 1/4" drill and a Lowe's brand 1/2" impact wrench. Not high dollar stuff by any means but stuff I could afford when I bought them. All work fine.

I don't use these tools daily (very often) but I've had no problems with dried seals or gaskets.

I'd recommend the oil at the start and the oil at the end procedure. I did this with a Senco nail gun for about 30 years till it got stolen. Never had a problem. It too would sit up for months and then get used like crazy on a project. Never had a problem.

This is the most relevant info you need. I have one, I use it often. If I'm working on something that will take a lot of time or will be an 'all day' thing then I will probably forget to oil tools throughout the day. Back when I was taught how to take care of air tools, we had about 20 of them throughout the shop and we put them on certain tools (ratchet, sander) that would be used heavily. Some spit oil here and there on short bursts, most it seems to keep them just as nice as if you stop every hour (or whatever it says on the instructions) and put 3 drops in.

Since oil is just as much to protect the insides of the tools from condensation as it is to lubricate them, I also use the oiler as I'm letting air out of the tank to oil the tools to put them away.

If you are the only user of your pneumatic tools, then save your money and

the extra hassle of an oiler at the end of a long hose, in favor of a can of

oil and the "hassle" of adding a few drops before the first use of the tool

on a daily basis. I haven't had any problems doing this over the course of

35 years. Further, I have been using some of them for over 35 years, and

there are a few of those that I got second hand. (However, I do

dissassemble, clean, inspect, and lubricate every so often.)

That's the best advise for any tool that sees intermittent use (impact guns come to mind first), but I would think that tools that see continuous use (such as a DA sander), could use more frequent oiling than that.
I have 3' long swivel whip hoses on my sanders (and a wet diamond grinder among a few other similarly used tools), with an inline oiler at the end of the whip. I just keep the reservoir filled, run it for a few hours, and then add another teaspoon of oil as needed.

The oiler doesnt conrol the flow very well, if I turn it down it seems to put out as much oil as if its all the way up. Also the regulator leaks but i cant narrow down exactly where unless I take it off the wall.

I plan on replacing it with a Milton brand filter regulator now automatic oiler. The oiler sits empty now. I have a few oil free nailers.
