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,…

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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the L828 is generally a robust and reliable engine when maintained properly. Its main weakness is the S-VT solenoid, which fails if oil changes are neglected. With regular servicing using the correct 5W-30 oil, these engines can easily exceed 200,000 km without major issues.
The most frequent issues are S-VT solenoid clogging, EGR valve carbon buildup, ignition coil failure, and valve cover gasket leaks. These are well-documented in Mazda service bulletins and are typically inexpensive to fix if addressed promptly.
The L828 was used in the second-generation Mazda 3 (BL platform, 2006-2013) and the first-generation Mazda 5 (CR platform, 2006-2010), specifically in the 2.0i variants. It was not used in any other Mazda models or licensed to other manufacturers.
Minor gains are possible via ECU remapping, typically yielding 5-10 kW extra. Significant power increases are limited by the naturally aspirated design and stock internals. Focus is usually on improving throttle response rather than large power gains.
Real-world fuel economy is around 7.5 L/100km (38 mpg UK) in combined driving for a Mazda 3. In city traffic, expect 9-10 L/100km (28-31 mpg UK), and on the highway, it can achieve 6.0-6.5 L/100km (43-47 mpg UK).
Yes. The L828 is an interference engine. If the timing chain were to fail catastrophically (which is rare), the pistons would collide with the open valves, causing severe internal engine damage requiring a rebuild.
Mazda specifies 5W-30 viscosity oil meeting their M5 standard or ACEA A3/B4. Using high-quality synthetic or semi-synthetic oil and changing it every 10,000 km is crucial for protecting the S-VT system and ensuring engine longevity.
