Production years 2013–2019 meet Euro 5 standards; all models comply uniformly as per.
The Mazda R207 is a 2,000 cc inline-four naturally aspirated petrol engine engineered for compact and mid-size vehicles (2013–2019). It combines direct fuel injection with dual variable valve timing to deliver responsive acceleration and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The Mazda R207 was used across Mazda's CX-5/Mazda3 platforms with transverse mounting. This engine received platform-specific adaptations-revised intake runners in the CX-5 and optimized exhaust routing in the Mazda3-and from 2015 the facelifted CX-5 adopted the R207TU variant with revised intake port geometry, creating interchange limits. 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 R207 delivers smooth performance and good efficiency, but early models (2013–2015) had significant reliability concerns, especially intake valve carbon buildup. Later revisions (post-2015) improved intake port design and ECU calibration to reduce deposits. Well-maintained examples with regular valve cleaning and proper oil changes can be very reliable.
The biggest issues are intake valve carbon buildup, ignition coil failure, and timing chain tensioner wear. Other complaints include oil leaks from the valve cover gasket and occasional PCV valve clogging. These are well-documented in Mazda service bulletins and owner forums.
This 2.0L petrol engine was used widely across Mazda's lineup. It appeared in the CX-5 (2.0L), Mazda3 (2.0L), and Mazda6 (2.0L) from 2013 to 2019. All versions share the same core design with minor calibration differences for vehicle weight and transmission pairing.
Aftermarket ECU tuning is common on the R207 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.
Very good. In a CX-5 2.0L (120 kW version) from around 2015, typical consumption is ~7.2 L/100km (city) and ~5.8 L/100km (highway), or about 45 mpg UK combined. Expect 40–50 mpg (UK) on mixed roads for a healthy R207. Real-world figures depend on driving style and load.
Yes. The R207 series is an interference engine. This means if the timing chain jumps or breaks, pistons can hit open valves, causing serious engine damage. That's why chain maintenance is critical — any warning rattles should be addressed immediately.
Mazda specifies a 5W-30 synthetic oil meeting Mazda Genuine Oil SN specification. Always use a quality oil designed for GDI engines and change it at regular intervals (around 15,000 km or as Mazda recommends) to ensure proper lubrication and minimize carbon formation.
