Used Mazda 3 Oil Pump

Every Mazda 3 variant has an oil pump — it is a fundamental part of any internal combustion engine, so whether your car is petrol or diesel, manual or automatic, all generations of the Mazda 3 from the first-generation BK (2003–2009) through the second-generation BL (2009–2013), third-generation BM/BN (2013–2019), and fourth-generation BP (2019–present) are fitted with one. There are no hybrid-only or electric-only variants of the Mazda 3 sold in the UK that would omit a conventional oil pump.

A 2007 car sits in the first-generation BK (2003–2009) and a 2011 car sits in the second-generation BL (2009–2013), so these are different generations with different engine families and the oil pump is very unlikely to interchange directly. Fitment of an oil pump follows the engine code above everything else, so the starting point is to check your V5 or run a VIN check to confirm your exact engine code, then give that to the breaker. Confirm compatibility against your registration with the breaker before purchasing.

No — on the Mazda 3, trim levels such as SE, SE-L, Sport, and GT Sport do not affect which oil pump is fitted; trim is a cosmetic and equipment distinction, not a mechanical one. What determines the correct oil pump is the engine code, which can vary within a generation (for example, different petrol and diesel engines were offered across the BM/BN generation), so two cars of the same trim can need different pumps if they have different engines. Check your engine code on your V5 and supply it to the breaker rather than relying on trim name alone.

Both a 2013 and a 2015 Mazda 3 sit within the third-generation BM (2013–2016 pre-facelift), so on paper they share the same generation, and an oil pump from the same engine code has a reasonable chance of being compatible. However, ancillary and mounting changes can occur mid-production without a formal facelift, so you should confirm compatibility against your exact registration and engine code with the breaker before buying. Never assume fitment purely on year or generation alone.

Yes, fuel type matters significantly — the petrol and diesel engines in the Mazda 3 are entirely different units with different oil pump designs, so a pump from a petrol engine will not be correct for a diesel car and vice versa. Within each fuel type there are also different engine codes across generations (for example, the 2.0 SKYACTIV-G petrol and the 1.5 SKYACTIV-D diesel in the BM/BN generation are distinct), so fuel type alone is not enough — always supply your exact engine code to the breaker. Your engine code is on your V5 logbook and is the single most useful detail you can give when requesting a quote on Findapart.

The BL and BM/BN generations are distinct model families with different engine ranges, and the oil pump is engineered to the specific engine it serves, so crossing this generational boundary is very unlikely to result in a compatible part. The engine code is the definitive guide — if by coincidence both cars share the same engine code (which would be unusual across these generations), there may be a case for compatibility, but you should confirm this directly with the breaker against both registrations. Do not attempt to cross this generation boundary without the breaker verifying fitment for your specific engine code.
