The Honda L15Z5 is a 1,496 cc, inline‑three naturally aspirated petrol engine produced between 2014 and 2020. It features port fuel injection, dual overhead camshafts (DOHC), and i-VTEC variable valve timing. In standard applications, it delivers 88 kW (120 PS) and 145 Nm of torque, with i-VTEC enabling a broad, flat torque curve for responsive city driving.
Fitted primarily to the third-generation Honda Jazz/Fit (GE8/9) and the second-generation Honda City (GM6), the L15Z5 was engineered for urban efficiency and low-cost ownership. Emissions compliance was achieved through precise fuel metering and a close-coupled three-way catalytic converter, meeting Euro 5 standards from launch.
One documented service consideration is the potential for timing chain tensioner wear, noted in Honda Service Bulletin A15-022. This can manifest as a brief rattle on cold startup and is typically addressed under warranty or via a revised tensioner part in later production runs.

Production years 2014–2020 meet Euro 5 standards across all applicable markets (EU Regulation (EC) No 715/2007).
The Honda L15Z5 is a 1,496 cc inline‑three naturally aspirated petrol engineered for compact city cars (2014-2020). It combines port fuel injection with i-VTEC variable valve timing to deliver smooth, predictable power and excellent fuel economy. Designed to meet Euro 5 standards, it prioritizes low running costs and reliability.

The naturally aspirated design offers predictable, linear power ideal for city commuting but lacks the mid-range punch of turbocharged engines. The port injection system is inherently resistant to intake valve carbon buildup, a significant advantage over direct-injection engines. Using the specified 0W-20 oil ensures optimal fuel economy and chain longevity. The engine's compact size aids accessibility for routine maintenance.
Oil Specs: Requires Honda 0W-20 specification for optimal fuel economy (Honda Owner's Manual). 5W-30 is an acceptable alternative.
Emissions: Euro 5 certification applies to all 2014–2020 models (EU Regulation (EC) No 715/2007). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Peak output requires 95 RON fuel (Honda TIS Doc. L15Z5-PERF).

The Honda L15Z5 was used across Honda's GE/GM platform with transverse mounting and was exclusive to Honda. This engine received platform-specific adaptations-reinforced engine mounts in the City for higher NVH standards-and from 2017 the facelifted Jazz received minor ECU and emissions revisions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, just below the exhaust manifold (Honda TIS L15Z5-ID). The 8th VIN digit for L15Z5-equipped vehicles is typically 'L'. The engine can be visually identified by its black plastic valve cover with "i-VTEC" branding. Critical differentiation from the L15B: The L15Z5 lacks a turbocharger and associated intercooler piping. Service parts, including the timing chain tensioner, were revised in 2016; pre-2016 parts may not be compatible with later engines (Honda SIB A15-022).
The L15Z5's primary reliability consideration is timing chain tensioner wear, with elevated incidence in high-mileage or infrequently serviced vehicles. Honda service data indicates this is a common wear item rather than a systemic failure, while owner reports frequently cite minor oil consumption in engines with over 150,000 km. Consistent use of correct oil and adherence to service intervals mitigates most long-term concerns.
