The Mazda PN26 is a 1,998 cc, inline — four petrol engine produced between 2010 and 2014. It features direct fuel injection, variable valve timing (VVT), and a high compression ratio of 13.0:1, delivering 150 kW (204 PS) with strong mid — range torque for responsive everyday driving. This engine was designed to balance performance with improved thermal efficiency over previous generations.
Fitted to the Mazda3 (BP) and Mazda6 (GJ) models including the 2.0T Skyactiv — G var…

Production years 2010–2014 meet Euro 5 standards; no earlier emissions standard applies .
The Mazda PN26 is a 1,998 cc inline-four turbo-petrol engine engineered for compact and mid-size vehicles (2010–2014). It combines direct fuel injection with continuously variable valve timing to deliver high specific power and efficient cruising. Designed to meet Euro 5 standards, it balances performance responsiveness with fuel economy targets.

The Mazda PN26 was used across Mazda's BP/GJ platforms with transverse mounting and licensed to Ford for certain European applications. This engine received platform-specific adaptations—revised intake manifold routing in the Mazda3 and enhanced intercooler plumbing in the Mazda6—and from 2012 the facelifted Mazda3 BP LCI adopted revised intake port geometry to reduce carbon buildup, creating interchange limits. Partnerships allowed Ford's 1.6 EcoBoost to share components from Mazda's direct injection system. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The PN26 delivers strong performance and good efficiency, but early models (2010–2011) suffer from intake valve carbon buildup due to direct injection. Later revisions (post-2012) feature modified intake ports to reduce deposits. With strict maintenance—including 10,000 km oil changes and periodic induction cleaning—the engine can be very durable. Avoid extended oil intervals and short-trip driving to maximize longevity.
The biggest issues are intake valve carbon buildup (leading to misfires and rough idle), turbocharger oil coking from aggressive driving, premature ignition coil failure, and high-pressure fuel pump wear. These are well-documented in Mazda service bulletins SI-13-002 and SI-14-011, particularly affecting pre-2012 models under urban driving conditions.
The PN26 was used exclusively in the Mazda3 (BP) and Mazda6 (GJ) from 2010–2014, specifically in 2.0T trim levels. Ford also used the engine as the basis for the 1.6 EcoBoost in the Focus Mk3 (2012–2014). It was never offered in MINI or other brands outside the Ford-Mazda partnership.
Aftermarket ECU tuning is common on the PN26 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Good for a turbo-petrol. In a Mazda3 2.0T, typical consumption is ~8.2 L/100km (city) and ~5.8 L/100km (highway), or about 45 mpg UK combined. Real-world figures vary with driving style, but expect 40–50 mpg (UK) on mixed roads for a healthy PN26. Economy improves significantly with consistent maintenance and avoidance of aggressive driving.
Yes. The PN26 is an interference engine. If the timing chain fails or jumps, pistons can strike open valves, causing catastrophic damage. Chain tensioner wear is rare but possible under neglected maintenance. Any unusual rattle from the timing cover should be inspected immediately to prevent expensive internal engine damage.
Mazda specifies Mazda Synthetic 5W-30 meeting API SN or newer spec. Always use full synthetic oil designed for direct-injection turbos and change it every 10,000 km or annually, whichever comes first. Longer intervals increase risk of carbon buildup and turbo oil coking. Do not substitute with lower-grade oils.
