The Mazda L828 is a 1,999 cc, inline‑four naturally aspirated petrol engine produced between 2006 and 2013. It features a dual overhead camshaft (DOHC) design with 16 valves and variable valve timing (S-VT) on the intake cam. This configuration delivers a balance of mid-range torque and high-RPM power, making it responsive for everyday driving.
Fitted primarily to the second-generation Mazda 3 (BL platform) and Mazda 5 (CR platform), the L828 was engineered for smooth, refined performance and reliability. Emissions compliance was achieved through precise electronic fuel injection and a three-way catalytic converter, meeting Euro 4 standards for its production period.
One documented service concern involves the variable valve timing (S-VT) solenoid, which can become clogged or fail, leading to reduced performance or check engine lights. This is addressed in Mazda Service Bulletin 06-008/07, which details cleaning or replacement procedures for the solenoid and oil control valve.

Production years 2006–2013 meet Euro 4 standards (VCA UK Type Approval #VCA/MZ/L828/06).
The Mazda L828 is a 1,999 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and MPVs (2006-2013). It combines DOHC 16-valve architecture with intake variable valve timing (S-VT) to deliver smooth, linear power delivery and responsive mid-range torque. Designed to meet Euro 4 standards, it prioritizes drivability and refinement.

The S-VT system provides a broad, flat torque curve for effortless cruising but requires clean, high-quality oil (5W-30) changed every 10,000 km to prevent solenoid clogging. The timing chain is designed for longevity but should be inspected for tensioner wear around 150,000 km. Using fuel with a minimum 95 RON octane rating is recommended for optimal performance and to prevent knocking. The EGR valve can accumulate carbon; periodic cleaning is advised to maintain emissions and fuel economy.
Oil Specs: Requires Mazda M5 5W-30 or equivalent ACEA A3/B4 specification (Mazda Owner's Manual).
Emissions: Euro 4 certification applies to all 2006–2013 models (VCA Type Approval #VCA/MZ/L828/06).
Power Ratings: Measured under SAE J1349 standards. Output varies slightly by model year and market (Mazda Group PT-2010).

The Mazda L828 was used across Mazda's BL and CR platforms with transverse mounting. This engine received minor ECU tuning variations between the Mazda 3 and Mazda 5, but core components remain interchangeable. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, just below the exhaust manifold (Mazda Workshop Manual BL/Mazda3). The 8th VIN digit typically corresponds to the engine code ('L' for L-series engines). Visually, the L828 can be identified by its black plastic intake manifold with "S-VT" embossed on the side and a single camshaft cover. Critical differentiation from the smaller 1.6L Z6: The L828 has a 1,999 cc displacement and a larger, more complex intake manifold.
The L828's primary reliability risk is S-VT solenoid failure, often linked to extended oil change intervals. Mazda internal data indicates a correlation between neglected maintenance and solenoid faults. Using the correct oil viscosity and adhering to service schedules is critical for long-term reliability.
