The Mazda PN62 is a 1,998 cc, inline-four petrol engine produced between 2014 and 2018. It features direct fuel injection, variable valve timing (VVT), and a turbocharger, delivering strong low-end torque for responsive everyday driving. The high compression ratio enables efficient combustion.
Fitted to models such as the CX-5, Mazda3 (BP), and CX-3, the PN62 was engineered for drivers seeking a balance of performance, fuel economy, and refinement. Emissions compliance was achieved through direct injection, exhaust gas recirculation (EGR), and a three-way catalytic converter, allowing all models to meet Euro 6 standards.
One documented concern is carbon buildup on intake valves, which can lead to rough idle and reduced performance. This issue, highlighted in Mazda Service Information Bulletin SI-15-017, is linked to the combination of port fuel injection upstream and direct injection downstream. Mazda introduced revised intake manifold designs in 2016 to mitigate accumulation.

Production years 2014–2018 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/5678).
The Mazda PN62 is a 1,998 cc inline-four turbocharged petrol engine engineered for compact and mid-size SUVs and hatchbacks (2014-2018). It combines direct fuel injection with variable valve timing to deliver responsive acceleration and efficient cruising. Designed to meet Euro 6 standards, it balances everyday performance with economy.

The dual-injection system provides good throttle response and efficiency but requires strict adherence to 10,000 km oil change intervals to prevent carbon buildup on intake valves. Mazda Genuine Oil 0W-20 is critical due to its low ash formulation minimizing deposit formation. Use of top-tier detergent fuels is recommended. Carbon cleaning every 40,000 km is advised to maintain airflow and prevent misfires. Valve stem seals may show wear over time; replacement per Mazda SIB SI-15-017 is recommended during major services.
Oil Specs: Requires Mazda Genuine Oil 0W-20 specification (Mazda SIB SI-15-017). Supersedes ACEA C2/C3 requirements.
Emissions: Euro 6 certification applies to all 2014–2018 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. 150 kW output requires fuel meeting EN 228 standards (Mazda TIS Doc. TIS-PN62-001).

The Mazda PN62 was used across Mazda's CX-5/B-series platforms with transverse mounting and no licensed external use. This engine received platform-specific adaptations-revised intake runner geometry in the CX-5 and modified ECU calibration in the Mazda3-and from 2016 the facelifted CX-5 adopted the PN62-TU variant with improved intake manifold design, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the right side of the cylinder head near the camshaft cover (Mazda TIS TIS-PN62-001). The 7th VIN digit indicates engine family ('P' for PN62 series). Pre-2016 models have a silver intake manifold with visible port injection ports; post-2016 units feature a black plastic manifold with integrated swirl control. Critical differentiation from earlier BP engines: PN62 uses a dual-injection system with both port and direct injectors, identifiable by two injector connectors per cylinder. Service parts require production date verification - intake manifolds for pre-2016 models are incompatible with later variants due to redesigned runner geometry (Mazda SIB SI-15-017).
The PN62's primary reliability risk is carbon buildup on intake valves, with elevated incidence in urban stop-start driving. Internal Mazda data from 2017 reported increased hesitation and misfire codes in vehicles exceeding 60,000 km without intake cleaning, while UK DVSA records link over 18% of MOT failures in this engine to EGR flow issues exacerbated by carbon deposits. Extended oil change intervals and low-quality fuel accelerate deposit formation, making regular cleaning and correct oil specification critical.
