Mazda 3 Sump Replacement Parts

These sit in different generations — the second-generation Mazda 3 (BL) ran from 2009 to 2013, while the third-generation (BM) ran from 2013 to 2019 — so you are crossing a generation boundary and the sumps are unlikely to be interchangeable. The safest route is to supply your engine code (found on your V5 or via a VIN check) to the breaker, as the sump follows the engine, not the year alone. Never assume a cross-generation swap will work without the breaker confirming it against your registration.

The third-generation Mazda 3 (BM) received a facelift in 2017, and while the engine codes available were largely carried over, ancillary and mounting details can change mid-production even on the same engine family. Name the facelift year to your breaker and give them your exact engine code so they can confirm whether the sump profile and fixings are identical to the donor car. Do not assume fitment across the 2017 facelift boundary without the breaker checking it against your registration.

Yes — fuel type matters significantly, because petrol and diesel engines are entirely different units with different sumps, oil capacities, and sump profiles. Always tell the breaker your fuel type alongside your engine code, as the engine code is the single most reliable way to ensure the correct sump is matched to your car. Quoting your registration number to the breaker will allow them to cross-reference both details at once.

The sump itself is an engine component rather than a gearbox component, so gearbox type (manual or automatic) does not directly determine which sump you need. What matters above all else is the engine code, which you can find on your V5 or via a VIN check, and this is what the breaker will use to source the correct part. Confirm your gearbox type with the breaker as a secondary detail in case any related oil-pan or clearance differences exist on your specific variant.

For a mechanical component like a sump, trim level — whether SE, Sport, or GT Sport — makes no difference to fitment, as these trims share the same engine options and the sump is determined entirely by the engine code. You may receive a sump that looks cosmetically different (different coating or casting marks) depending on which donor car the breaker strips, but this will not affect function. Give the breaker your engine code and year rather than your trim name, and they will match the correct part.

Knowing the year and fuel type is a good start and places your car in the third-generation BM range (2013–2019), but the engine code is more reliable than the displacement alone, as engineering revisions can occur within the same 2.0 petrol family across model years. Your engine code is printed on your V5 logbook or can be retrieved via a VIN check, and supplying it to the breaker gives them the best chance of finding a confirmed match. Always let the breaker verify fitment against your full registration before purchasing.
