CarCompatibility exists to answer one question reliably: will this part actually fit my car? Here’s how our editorial team gets to an answer we’re willing to publish.
1. We work from manufacturer and OE-supplier data
Original-equipment specifications and established supplier catalogues come first. Generic listings and marketplace titles are treated as leads to verify, not facts — they’re a common source of wrong-part purchases.
2. We match the codes that actually govern fit
Fitment usually comes down to standard, measurable things: battery type/group size, capacity (Ah) and cold-cranking amps (CCA), and Start-Stop technology (AGM/EFB); wiper blade lengths per side and fitting type (hook, bayonet, push-button, pinch-tab); bulb fitment codes (e.g. H1/H4/H7); tyre size markings; and oil viscosity and manufacturer approvals. We work from those, not the marketing.
3. We account for model, year, engine and build date
The same model can take different parts across a facelift or engine option. We specify the variant a fitment applies to rather than implying “one size fits the model.”
4. We tell you when to confirm by registration or VIN
For anything where the correct part genuinely depends on your exact vehicle, we say so plainly and point you to a registration/VIN check rather than presenting a guess as certainty.
5. We keep it current
Ranges get facelifted and superseded. We re-verify our guides on a regular cycle and date-stamp every page with when the fitment data was last checked.
6. Our recommendations and affiliate links
