Oil Manual

Oil spec checker

Compare the manual requirement against the bottle label. Start with viscosity, then check API, ILSAC, ACEA, dexos, and OEM approvals as separate fields.

Paste manual oil section

The checker highlights possible grade/spec/capacity hints from pasted text, but you still choose the official fields yourself.

Paste bottle label text

The checker highlights possible grade/spec hints from the pasted label text. It does not infer missing approvals or replace the exact bottle wording.

Common label cues

API Donut
Back-label mark that lists service category and viscosity.
Starburst
Front-label mark for eligible ILSAC fuel-economy oils such as GF-7A.
Shield
Mark for eligible low-viscosity 0W-16 ILSAC oils such as GF-7B.
OEM approval
Brand-specific approval like dexos, VW, MB, BMW, Ford, Honda, or Porsche.

This checker is conservative. It does not read photos, certify oil, infer approvals, or treat a related spec as an exact match.

What the checker does, and does not, infer

  • It compares the grade as an exact field first: a viscosity mismatch is not hidden by a good API or OEM label.
  • It checks 24 selectable spec labels across 11 label families: API, ILSAC, GM, ACEA, VW, BMW, Mercedes-Benz, Ford, Honda, Porsche, JASO.
  • Related labels are not treated as exact approvals. If the manual says one approval and the bottle shows a related one, the result stays unknown until the manual or manufacturer says it is allowed.
  • Paste boxes are only hint extractors. The final result comes from the fields you select, not from photo recognition or certification data.

Manual-first workflow

Use the result safely

A compatibility result is only as good as the fields you entered. Move through these steps before buying oil or saving a service note.

  1. 01Find the manual's exact oil wordingCapture viscosity, specification, capacity, interval, engine, and market before checking a bottle.
  2. 02Build a source evidence packetTurn the manual oil section into a copyable packet for review or correction.
  3. 03Decode the bottle labelUse API Donut, Starburst, Shield, and OEM approval cues without treating them as automatic matches.
  4. 04Verify the approval or licenseCheck the exact label or license identifier against the current issuer source.
  5. 05Save the result in your garageKeep a local-only oil-change card with grade, spec, capacity, and service interval notes.
