The GM L76 is a 6,162 cc, naturally aspirated V8 petrol engine produced between 2008 and 2013. It features dual overhead camshafts (DOHC), direct fuel injection, and variable valve timing (VVT) on both intake and exhaust camshafts. This architecture delivers high power output and a broad torque curve, producing 304 kW (415 PS) and 556 Nm of torque in standard applications.
Fitted primarily to the Holden Commodore (VE) and HSV performance variants in Australia and New Zeal…
Production years 2008–2013 meet Australian Design Rule 79/01 (ADR79/01) standards (Australian Government DOTARS Certificate #ADR79-01-08).
The GM L76 is a 6,162 cc V8 naturally aspirated petrol engine engineered for performance sedans (2008-2013). It combines direct injection with dual overhead camshafts and cylinder deactivation to deliver exhilarating power and respectable efficiency for its class. Designed to meet ADR79/01 standards, it balances high performance with regulatory compliance.

The GM L76 was introduced as a performance engine option for Holden's VE platform sedans with longitudinal mounting. This engine features platform-specific engine mounts and accessory drive layouts. All applications share identical core engine specifications and calibration. 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.
The L76's primary documented focus is on the reliable operation of its Active Fuel Management (AFM) system in high-temperature environments, with no widespread mechanical failure campaigns issued. GM Holden engineering data indicates robust performance under normal operating conditions, while adherence to the specified dexos1™ oil is critical for maintaining lifter function and preventing AFM-related drivability issues. Neglecting oil changes or using incorrect oil specifications is the primary factor leading to potential AFM system faults.
Analysis derived from GM Holden technical bulletins (2008-2013) and Australian Design Rule compliance data. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The GM L76 is generally considered a robust and reliable engine for long-term use. Its naturally aspirated V8 design is proven and durable. The primary focus for longevity is strict adherence to oil change intervals using only dexos1™ oil to ensure the Active Fuel Management system operates correctly. With proper maintenance, it should provide many years of dependable, high-performance service.
The most commonly discussed issue is related to the Active Fuel Management (AFM) system, specifically lifter failure causing ticking noises and misfires. Carbon buildup on intake valves (common to direct injection engines) and coolant leaks from the water pump are also known, repairable issues.
The L76 6.2L V8 was used exclusively in Australian-market vehicles: the Holden Commodore (VE) SS, SS-V, and SS-V Redline variants, as well as the HSV Clubsport R8 and Senator Signature models, from 2008 to 2013.
Yes, the L76 responds very well to tuning. ECU remaps can typically unlock an additional 20-30 kW and 40-60 Nm by optimizing ignition timing and fuel maps. More significant gains are possible with a performance exhaust and intake. Its large displacement and robust internals offer excellent tuning potential.
Fuel economy is typical for a large performance V8. For a 2010 Holden Commodore SS, expect approximately 15.5 L/100km city, 9.5 L/100km highway, and 12.8 L/100km combined. Real-world figures will depend heavily on driving habits.
Yes. The GM L76 is an interference engine. This means that if the timing chain were to fail or jump significantly, the pistons could collide with the open valves, resulting in severe internal engine damage requiring a costly rebuild or replacement.
GM mandates the use of dexos1™ specification oil, typically in 5W-30 viscosity. Using any other oil, including non-dexos oils, can void the warranty and potentially lead to AFM system malfunctions or engine damage. Always check your owner's manual for the exact specification.
