The directory organises Mazda engines three ways: by engine code (like SHY1, T3Y4, P5-AT), by size (1.5 to 3.3 litres) and by family (SkyActiv-G petrol, SkyActiv-D diesel, SkyActiv-X). Find your code, confirm it on the engine, then compare quotations on evidence.

How do you use the directory?
Three steps: find your engine (registration or code), confirm it on the vehicle (marking + Reg), then compare quotations with the evidence checklist. That order prevents the most common buying mistakes.
Family guides: SkyActiv-D; quotation routes: get quotes.
Which route should you choose?
Used, reconditioned or supply-and-fit — every code in this directory supports all three. Pick by how long you're keeping the car and how much paperwork you want to manage.

How do you verify any engine before you buy?
Run these five checks before any money moves — code first, price last.
Code: photograph the marking on the actual engine and match it to your Reg.
Configuration: confirm model, year, drivetrain and emissions equipment.
Evidence: rebuild records for reconditioned; donor Reg, mileage and tests for used.
Components: get the included-parts list in writing.
Terms: compare warranty, delivery and returns like-for-like.
Mazda engine directory questions
Where do I start if I don't know my engine code?
With your registration — it identifies the model and derivative. Then confirm the code stamped on the engine itself.
Do you cover petrol and diesel?
Yes — SkyActiv-G petrols, SkyActiv-D diesels and SkyActiv-X. Each code has its own guide with specs, compatibility and faults.
Why do some codes have more detail than others?
Verified records differ by code — some have full application data, others are restricted. We publish what's confirmed and flag what isn't.
Can I get quotes for any engine in the directory?
Yes — submit your registration and the network returns used, reconditioned and supply-and-fit quotations for your application, with evidence attached.

Start with your registration to identify the exact code and derivative, then compare quotations with the evidence attached. For official specifications and service documentation, cross-check against official documentation — source: Mazda UK's official resources.
