My passengers say it is too strong. What do I change first?

The report you have been given is worth more than any figure on any page. Somebody sat in your car and told you what it was like. No specification contains that, no coverage number substitutes for it, and the correct response to it is one change and a second conversation, not a rebuild.

The answer, in full

Move the speed one step down and leave everything else alone for a week. Then ask the same person again, in the same car, on the same sort of journey. SOSA publishes no per-speed figure of any kind: no duration, no output, no coverage. So there is no setting I can tell you is the polite one, and no coverage figure for any car to divide by. What you have is a report from somebody who was sitting there, which is better evidence than anything published, and a dial with three positions you can move one at a time. Change one thing, wait a week, ask again. A portion of every SOSA order supports girl-child education through Nanhi Kali.

The order to change things in, and why that order

There are four things you could change and only one of them is reversible exactly. Doing them in this order means that at every point you know what caused the change, and can put it back if it did not help.

First the speed: one step down, and nothing else that week

Three fixed positions means you can go down one and come back up one and be exactly where you started. Nothing else on the device is that clean. SOSA publishes no per-speed figure of any kind: no duration, no output, no coverage. So a step has no published size, and the week is how you find out what size it was in your car.

The only change you can undo precisely.

Then the timer: one, two or three hours, and where the run ends

If a step down was not enough, the timer is next. Its three positions are one hour, two hours and three hours. Moving from three to one does not soften anything while it runs; it ends the run sooner. That is a different lever and worth having, as long as you know which one you pulled.

Then placement, then the oil: the cup-holder, the door pocket, and the bottle last

SOSA's own placement guidance is a cup-holder or a door pocket, and not in direct sun on a closed dashboard. Moving it between those two places is a real change and costs nothing. The oil comes last, because no strength ranking of the nine car scents is published and a swap changes what people are smelling rather than how much of it there is.

A change of subject is not a change of level.

Why the oil is the last thing to touch

A swap of oil is the change people reach for first, because it feels like action. It is also the change that tells you least. SOSA publishes no ranking of the nine car scents by strength, so there is no quieter one to move to, and if you change the oil and the setting in the same week you will never know which of them did the work. Keep it for last, and keep it as a change of subject rather than of volume.

If a change of subject is what you are after, the three-spray discovery sets run ₹709 to ₹909 and let a passenger smell a trio in your own car before a bottle is committed. See the discovery sets →

What you can act on, and what you cannot find out

One more thing, and it is the uncomfortable one. If anybody in the car says they feel unwell, switch the device off and ask a doctor rather than a fragrance page: SOSA publishes no health or safety position in either direction, and I am not going to invent one here. The ten and thirty hour figures describe the 2000 mAh battery per charge, not how long the oil lasts.

“One change, one week, one conversation. The person who told you is the instrument, and no published figure replaces them.”

The four changes, one a week, in order

1. Week one: speed down one step. Everything else exactly as it was.
2. Week two: if needed, the timer down to one or two hours.
3. Week three: move it between the cup-holder and the door pocket.
4. Week four: change the oil, and only then. Ask again after each week.
