Two readings, not one
Long enough that one unusual week cannot swing it, and no longer than that. For most people this is one ordinary month, then a second month to find out how ordinary the first one was.
The honest answer to how long is: longer than you want and shorter than you fear. I have no published average to offer you as a shortcut, because SOSA publishes none, and an invented one would simply move the guesswork from your glovebox into my paragraph.
The answer in 30 seconds
How long do I need to log before the number means anything?
- In one line. One ordinary month for a reading, a second ordinary month for confidence. There is no published average to check either of them against.₹3,999
- The short answer. One ordinary month is the shortest run worth trusting, and a second month is what tells you whether the first was ordinary. SOSA publishes no rate of use, so there is nothing to check your log against except another month of your own. Safar is Rs 3,999.
- If you only remember one thing: one month gives you a reading and two months give you confidence. The second one costs nothing except leaving the card where it is.
- What is the shortest useful run? One ordinary month. A week of entries describes that week, and a single long drive inside it will swing the whole reading.
- When do I stop? When a second month lands close enough to the first that you have stopped caring about the difference between them.
- What ruins a month? A holiday, a fortnight when the car sat still, a change of speed, a change of scent, or a refill poured in halfway through.
The answer, in full
One ordinary month, and then one more. Here is the reasoning rather than the rule. A week of entries describes a week, and inside any given week one long motorway run or three days of working from home moves the line on the glass more than your habits do, so a week-long log mostly measures the week you happened to pick. A month is long enough to average over the usual spread of your driving without asking you to keep a card for a season. The second month is the one that does the real work: it tells you how much of the first reading was you and how much was the week your sister borrowed the car. SOSA publishes the refill price, ₹1,049 for 100 gm and ₹1,849 for 300 gm, and no rate of use, so there is no published average sitting behind this to sanity-check your log against. Two of your own readings are the sanity check. A portion of every SOSA order supports girl-child education through Nanhi Kali.
How long, and what makes a month count
Three questions in order: what the shortest honest run is, what the second month adds, and what disqualifies a month you have already logged.
One ordinary month: the shortest run worth trusting
A month is long enough that one unusual drive is a part of the reading rather than the whole of it, and short enough that you will actually finish it. If your driving runs in a weekly rhythm, four of those weeks is the natural unit. If it runs in a monthly rhythm because of the way you work, the month is the unit anyway. Shorter than that and you are measuring the week you chose, not the way you drive.
A week of entries describes a week. That is all it can do.
The second month: what tells you how ordinary the first one was
The first reading is a number. The second reading is what tells you whether the first one meant anything, and it is nearly free: the card is already ruled, the pen is already in the glovebox, and the only work is not stopping. If the two land close together, you can put the card away and go back to glancing at the line. If they do not, you have learned something real about the spread in your own driving, which no published average could have told you.
What disqualifies a month: the five things that end a run early
A fortnight away with the car parked. A holiday that was all motorway. A change of speed setting, because SOSA publishes no per-speed duration to convert between settings. A change of scent, because nothing published says whether one oil behaves like another. And a refill poured in halfway, which leaves you with two marks that no longer describe one stretch of driving. Any of those and I would start the month again rather than keep the reading.
Starting again costs you a month. Keeping a spoiled month costs you the figure.
Does changing scent reset the clock?
I would call it a reset. 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 tells you whether a switch should change your reading. Write the name of the oil on the card, start the month again, and after two or three oils you will have something nobody else has.
A two-month log wants a refill in the cupboard rather than an emergency in week six. The nebuliser refill oil is ₹1,049 for 100 gm and ₹1,849 for 300 gm. See the nebuliser refill →
How long you log, and what it buys you
| What the record says | |
|---|---|
| A week | Enough to prove the method works and to teach you to write the hours down. It describes the week you logged and not much else. |
| One ordinary month | A reading you can act on, with the usual spread of your own driving inside it. |
| Two ordinary months | The same reading, plus an idea of how much it moves. This is where I would stop. |
| A published average to compare against | There is none, in any form. SOSA publishes the refill price and no rate of use, so another month of your own is the only comparison available. |
After two months the card has done its job and you can go back to looking at the line on the glass when you get in. Keep the card, though. The day you change the speed or the scent, it is the thing that tells you what the old setting looked like.
“One month gives you a reading. The second month tells you whether the reading was about your driving or about that particular month.”
Logging long enough, in four steps
- Log one ordinary month before you draw any conclusion at all.
- Keep the card going for a second month without changing anything.
- Start the month again if the speed, the scent or the bottle changed.
- Stop when two readings land close enough to stop interesting you.
