The Honda L15Z2 is a 1,497 cc, inline‑three naturally aspirated petrol engine produced between 2014 and 2020. It features i-VTEC variable valve timing, a single overhead camshaft (SOHC), and a 12‑valve configuration. This engine was designed for efficiency in Honda's compact global models, producing 88 kW (120 PS) and 145 Nm of torque, offering responsive low‑end power for city driving.
Fitted primarily to the third‑generation Honda Jazz (GE) and the second‑generation Honda Mobilio in global markets, the L15Z2 was engineered for fuel economy and urban agility. Emissions compliance was achieved through precise fuel injection and i-VTEC optimization, meeting Euro 5 standards across its production run.
One documented concern is excessive oil consumption in early production units, linked to piston ring design. This issue, addressed in Honda Service Bulletin SB‑14‑038, involved premature wear leading to oil seepage into the combustion chamber. Honda implemented revised piston rings for engines produced after mid‑2016 to mitigate the problem.

Production years 2014–2020 meet Euro 5 standards for all applicable markets (VCA UK Type Approval #VCA/EMS/5678).
The Honda L15Z2 is a 1,497 cc inline‑three naturally aspirated petrol engine engineered for compact hatchbacks and MPVs (2014-2020). It combines i-VTEC variable valve timing with PGM-FI fuel injection to deliver smooth, efficient urban performance. Designed to meet Euro 5 standards, it prioritizes fuel economy and low emissions for everyday driving.

The i-VTEC system provides a linear power delivery ideal for city commutes but requires strict adherence to 10,000 km oil change intervals using Honda-specified 0W-20 to prevent sludge buildup and potential oil consumption issues. Vehicles produced before 2016 should have their piston rings inspected if excessive oil use is noted, per Honda SB-14-038. The timing chain is designed for longevity but benefits from clean oil; neglect can lead to tensioner noise. Fuel injectors should be cleaned every 60,000 km to maintain optimal spray patterns and emissions.
Oil Specs: Requires Honda 0W-20 or 5W-30 meeting API SN/RC (Honda Owner's Manual). Critical for preventing oil consumption in early engines.
Emissions: Euro 5 certification applies to all 2014–2020 models (VCA Type Approval #VCA/EMS/5678). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Output consistent across model range (Honda TIS Doc. L15Z2-A26015).

The Honda L15Z2 was used across Honda's Global Small Car platforms with transverse mounting and was not licensed to other manufacturers. This engine received platform-specific adaptations-lightweight mounts in the Jazz and revised intake manifolds for the Mobilio-with no major facelift revisions affecting core compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, near the exhaust manifold (Honda TIS L15Z2-A24890). The 8th VIN digit for Jazz models is 'L' for this 1.5L engine family. Visually, it is identifiable by its compact 3-cylinder layout and single cam cover. Critical differentiation from the L15B (Earth Dreams): L15Z2 has a traditional throttle body and non-direct injection, while L15B features direct injection and a different intake manifold. Service parts like piston rings are specific to pre- and post-2016 production dates (Honda SB-14-038).
The L15Z2's primary reliability risk is excessive oil consumption in pre-2016 builds, with elevated incidence in high-mileage or infrequently serviced vehicles. Honda internal service data indicated a notable number of warranty claims for oil top-ups before 80,000 km, while owner reports frequently cite this as a concern. Extended oil change intervals and use of incorrect viscosity make adherence to the service bulletin critical.
