Yours, and only yours
Four uses, and one thing I will not do with it. The figure you measured is the only one in this whole subject that was made out of your own driving, and it is worth more than the published average that does not exist.
The temptation at the end of a measurement is to turn it into a tidy figure per month and quote it. I will not print one, and I would be careful about repeating yours. It was measured on your commute, at your setting, with your oil in the bottle, and the moment it leaves that context it is somebody else's average again.

The answer in 30 seconds
What can I actually do with my own consumption figure once I have it?
- In one line. It picks the refill weight, times the order, and tests a change of setting. It is your figure, measured on your driving, and not a published one.₹1,049
- The short answer. Use it to choose a refill weight, to decide when to order rather than when to worry, and to check whether a change of setting did anything. The two refill prices are published, Rs 1,049 for 100 gm and Rs 1,849 for 300 gm, and the rate of use is not, which is why your own figure is the one that matters.
- If you only use it for one thing: use it to pick the weight. The two prices and their two weights are published, so that decision is arithmetic rather than guesswork once your own figure tells you how much oil you actually get through.
- What is it actually for? Choosing between the two refill weights, deciding when to order, and testing whether a change you made to the setting did anything.
- Can I turn it into a cost per month? Not on this page. The rate half of that sum is yours rather than SOSA's, and a figure printed here would be read as a published one.
- Can I give the figure to a friend? Only with the hours and the setting attached, and even then it describes your driving and not theirs.
The answer, in full
Four things, and then the thing I will not do. First, it picks the refill weight: divide ₹1,849 by three and set the result against ₹1,049, which is a comparison between two published prices per 100 gm, and your own figure is what tells you whether the larger weight is a sensible amount of oil to have in the house. Second, it tells you when to order, so that the line on the glass becomes a note to yourself rather than a problem on a Monday morning. Third, it lets you test a change: measure a month on one speed, move the setting, measure another month, and you have your own comparison where SOSA publishes no per-speed duration at all. Fourth, it stops you planning around somebody else's number, because there is no published rate of use for anybody to have given you. What I will not do is multiply your figure by a published price and print the answer here as a running cost, because the rate in that sum is yours and the moment it appears in my paragraph it reads as SOSA's.

Four uses for a figure nobody published
Three of these are decisions you were making anyway, slightly better informed. The fourth is the one people do not expect, and it is the reason I would keep the card after the measurement is done.
Choosing the weight: published prices, your own volume
The nebuliser refill is ₹1,049 for 100 gm and ₹1,849 for 300 gm. Divide the second by three and set it against the first and you have a real comparison per 100 gm, because both halves of it are printed on the product record. What that sum cannot tell you is whether 300 gm is a sensible amount of oil for your house to hold, and that is precisely the question your own measurement answers.
Two published prices, two published weights, one honest division.
Timing the order: watch the line, not the calendar
Once you know roughly what a month of your driving does to the glass, the mark becomes a trigger instead of a worry: when the line reaches the point you chose, you order. There is still no published interval to put in a diary, and you no longer need one, because the thing on the glass is better information than a date would have been.
Testing a change: your own comparison where no figure is published
Measure a month at one speed. Move the setting. Measure another month, with the hours written down both times. You now have a comparison between two setups on your own driving, which is something SOSA publishes nothing about: there is no per-speed duration on the record, so this is the only way the question gets answered at all. Keep the setting on the card or the pair of readings means nothing.
The only per-setting comparison that exists is the one you make.
Does the figure travel across scents?
The figure belongs to the oil you measured. SOSA publishes the scent names and a fragrance pyramid for each, no ranking across the nine and no consumption figure for any single one of them, so nothing published says whether a figure from one oil applies to another. If you rotate scents, a card per oil is the honest version, and it is three lines of handwriting rather than a project.
The figure is only useful if the oil is there when the line gets low. The nebuliser refill is ₹1,049 for 100 gm and ₹1,849 for 300 gm. See the nebuliser refill →
What your figure can and cannot do
| What the record says | |
|---|---|
| Choose between the two refill weights | Yes. Both prices are published, ₹1,049 for 100 gm and ₹1,849 for 300 gm, and your own volume is the part the prices cannot supply. |
| Tell you when to order | Yes, through the mark on the glass rather than through a date. No interval is published and you no longer need one. |
| Compare one setting against the next on your own driving | Yes, with the hours and the setting logged both times. No per-speed duration is published, so this comparison exists nowhere else. |
| Become a figure you can quote as SOSA's | No. It was measured on your car, at your setting, and SOSA publishes no rate of use that it could ever be a version of. |
The one use I would avoid is handing the figure to somebody with a different car and a different commute as though it were a specification. It is a measurement with your name on it, which is what makes it worth having and also what makes it unexportable.
“Your figure chooses the weight, times the order and tests a setting. What it is not is a published number, and it never becomes one by being repeated.”
Using your own figure, in four steps
- Divide Rs 1,849 by three and set it against Rs 1,049 per 100 gm.
- Let your own volume decide which of the two weights to keep.
- Order when the line reaches the mark you chose, not on a date.
- Log a month per setting if you want one speed compared with another.

Both prices are published and the per-gram comparison is exact. What your own month adds is the volume, which no published figure was ever going to supply.
