Hi All!
Recently, I have been looking at on-bike chain oilers as a means to keep the chain nicely lubricated while on the move in wet conditions. Rohloff no longer market theirs; at any rate, like all I have seen, it was intended for use with derailleur drivetrains and consisted of an oil reservoir that applied a metered flow of oil on-demand via small-diameter tubing, terminating in some specially grooved rear derailleur pulleys.
The only similar thing on the market today is the Scottoiler, which has recently caught my eye. Some reviewers and proponents claim it greatly narrows the gap betweenderailleurs and Internally-Geared Hubs (like Shimano's Alfine/Nexus and Rohloff's Speedhub) in wet and/or muddy conditions.
Here are some links...

It's reservoir is not machined aluminum with a plunger, rather it is a plastic bag called a "squid". The user squishes it by hand and a fresh batch of oil douses the chain. Looking at the reviews, it seems to use rather a lot of oil and the oil -- seeming a
water-based lubricant (!) -- is very short-lived. the basic idea seems to be to keep the chain lubricated with
something and frequently. The heavy dousings apparently wash off grit, though I am skeptical. The usual familiar black grunge is produced as a result of aluminum oxides, ground up dirt, and general environmental debris, but it apparently washes off with water -- including from the drivetrain, which makes me think this might not be the best lubricant. I see why it needs frequet reapplication.
At any rate it is intriguing, and winter is coming with its usual rains, snow, and generally wet conditions, so I'm wondering if any Forum members have experience with the ScottOiler or any similar product. It might work for some, but doesn't apear useful to my needs (due to oil composition and the means for dispensing it pus the requirement to use special deraillewur pulleys). It would be nice to find and mount a compact on-bike oiler to the Nomad, but re-oiling the chain from a small bottle is not on onerous task, and goes by pretty quickly. Kind of hard to improve on in most circumstances, but for mountain-biking in mud and dirt, an oiler just might do the trick, provided it was used frequently. Several of the reviews above mention "hearing" when a re-oiling is needed (I'll bet one can!).
A Hebie Chainglider or similarly light and robust chaincase would seem to put the lights out on any sort of oiler. Keeping the chain dry and clean and well-oiled is the exclusive province of a Chainglider...but not for derailleur drivetrains.
Thoughts?
Best,
Dan.
