The Mitsubishi 6G75 is a 3,828 cc, V6 naturally aspirated petrol engine produced between 2003 and 2021. It features a double overhead camshaft (DOHC), 24 valves, and Mitsubishi’s MIVEC variable valve timing on both intake and exhaust camshafts in later variants. In standard form it delivered 177–206 kW (241–280 PS) with torque between 337–363 Nm, offering smooth high‑torque delivery for large SUVs and performance sedans.
Fitted to models such as the Pajero / Montero (V8…
Production years 2003–2010 meet Euro 4 standards; 2011–2021 models meet Euro 5 depending on market (Japan Automobile Manufacturers Association Type Approval #JAMA/6G75/2011).
The Mitsubishi 6G75 is a 3,828 cc V6 naturally aspirated petrol engine engineered for full-size SUVs and performance applications (2003–2021). It combines DOHC architecture with optional dual MIVEC variable valve timing to deliver broad torque and smooth high-RPM power. Designed to meet Euro 4 (and later Euro 5) standards, it balances towing capability with daily refinement.

The Mitsubishi 6G75 was used across Mitsubishi's V80/V90/ZJ/CZ4A platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts and oil cooler in the Pajero and simplified MIVEC calibration in the Outlander—and from 2011 the facelifted Pajero models adopted updated emissions hardware, creating minor ECU interchange limits. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from Mitsubishi technical bulletins (2008–2020) and EU national vehicle inspection data (2015–2023). 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
Yes, with proper maintenance. The 6G75 is robust and non-interference, with strong internals. Early Pajero models (2003–2009) had MIVEC solenoid issues, resolved by 2010. Regular oil changes with 5W-30 API SN oil and avoiding excessive idling ensure longevity beyond 250,000 km.
MIVEC solenoid failure (early Pajero), oil consumption in high-mileage engines, carbon buildup on intake valves, and rare timing tensioner wear. Most issues are preventable with correct oil and service intervals. Documented in Mitsubishi TSBs ENG‑08‑015 and ECU‑11‑004.
The 6G75 powered the Pajero/Montero (2003–2021), Outlander (2007–2012), limited Lancer Evolution X special editions (2008–2010), and Grandis (2003–2011). All are 3.8L petrol variants. Note: it replaces the 6G74 in most large applications. No cross-manufacturer licensing occurred.
Yes, especially the dual MIVEC variants. Bolt-on cams, headers, and ECU remaps can yield +20–30 kW. The block is strong, but head gasket and fuel system upgrades are recommended beyond 220 kW. Tuning should use 98 RON fuel and retain MIVEC functionality for drivability.
In a Pajero 3.8L (177 kW), expect ~13.5 L/100km city and ~9.2 L/100km highway, or ~21 mpg UK combined. Outlander models average 12.8 L/100km due to lighter weight. Real-world mixed driving typically yields 19–24 mpg UK. Economy suffers if MIVEC is disabled or carbon buildup occurs.
No. The 6G75 is a non-interference engine. If the timing chain fails, pistons will not contact valves, preventing catastrophic internal damage. This enhances long-term reliability, though timing components should still be inspected at high mileage.
Mitsubishi specifies 5W-30 synthetic oil meeting API SN or ILSAC GF-5 standards. ACEA A5/B5 is acceptable. Change every 10,000 km or 12 months. Correct oil is critical for MIVEC solenoid function and preventing sludge in high-heat applications.
