The Qualified Thirty

Ranked by sold-per-month on the 12 September capture. The 11 September column is blank where a listing sat below the old hundred-a-month gate and was never captured that day. “Verified by” records how the single-grade check was made: from the variation table pulled through the API, or by opening the page.

T1 Mall badge, T2 Preferred or Preferred+, T3 no badge but three years old or more, T4 no badge and younger than three years.

These three are the shops that occupy the position AGOGO would occupy as Top1Oil’s official Thai distributor. Note the catalogue sizes against the resellers in section 5 — a brand store carries its own range and nothing else.

One column is missing from that table because Shopee does not publish it: how much of each shop’s traffic is brand search rather than category search. A buyer typing “Motul” and a buyer typing “น้ำมันเครื่องเบนซิน 5W-30” are different customers, and the second is the one this shelf is competing for.

Two of the eleven provisional listings did not survive the page check. Both were single-grade by title, which is exactly the failure mode title filtering cannot catch.

A pattern worth naming. Every ENEOS Top Racing listing that has reached a page check has been rejected — three of three across both rounds, on synthetic grade or on multi-grade options. If a fourth appears, treat it as suspect before opening it rather than after.

Audited on 12 September. Accounting, tier assignment and de-duplication all check out: no listing appears in two buckets, no duplicates, every listing carries shop data, and eighty screened listings reconcile to thirty pure plus thirty mixed plus nineteen out of spec plus one to judge. Three things are worth stating plainly rather than leaving implicit.

One listing on the roster, H AUTO’s “ใหม่ API SP เบนซิน SAE 5W-30”, has no 12 September figure at all: it did 418 a month on the 11th and had left the first 120 results entirely by the 12th. It is held by the grandfather clause and is the single most likely listing to drop off next.

Not yet captured for any listing: price per litre, the image set, the description copy and the review text. Price per litre needs option-level pack sizes from the product endpoint, which is rate-limited.
