The Lexus 2GR-FSE is a 3,456 cc, V6 direct-injection petrol engine produced between 2007 and 2014. It features Toyota's D-4S dual injection system combining port and direct fuel injection, along with dual overhead camshafts and variable valve timing (VVT-i). This architecture delivers strong mid-range torque for responsive acceleration while maintaining improved fuel efficiency over conventional port-injected designs.
Fitted to models including the IS 250, GS 250, LS 460, and RX 350, the 2GR-FSE was engineered for smooth, refined performance with emphasis on low-end torque delivery and quiet operation. Emissions compliance was achieved through advanced combustion control, exhaust gas recirculation (EGR), and a three-way catalytic converter, enabling compliance with Euro 4 and later Euro 5 standards depending on market and model year.
One documented concern is carbon buildup on intake valves due to the lack of fuel washing in the direct-injection portion of the system. This issue, highlighted in Toyota Technical Service Bulletin TSB-0128-11, is exacerbated by frequent short-trip driving and extended oil change intervals. Toyota introduced revised intake manifold gaskets and recommended more frequent induction cleaning procedures for affected models after 2010.
Production years 2007–2010 meet Euro 4 standards; 2011–2014 models may have Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Lexus 2GR-FSE is a 3,456 cc V6 naturally aspirated petrol engine engineered for mid-size luxury vehicles (2007-2014). It combines direct fuel injection with port fuel injection (D-4S) to deliver balanced power delivery and reduced intake valve deposits. Designed to meet Euro 4 and market-specific Euro 5 standards, it balances high-output performance with improved thermal efficiency.

The D-4S system provides excellent throttle response and reduced knock tendency but requires strict adherence to 10,000 km oil changes using full-synthetic 5W-30 to prevent intake valve carbon accumulation. High-quality, top-tier detergent fuels are essential to mitigate deposit formation. Extended idling or frequent short trips accelerate carbon buildup, necessitating periodic induction cleaning every 50,000–80,000 km as per Lexus SIB 0128-11. The chain timing system has no scheduled replacement interval but should be inspected during major services for wear or stretch. Fuel quality below EN 228 specifications can trigger misfire codes and reduce power output.
Oil Specs: Requires Toyota Genuine Oil 5W-30 (API SN / ILSAC GF-5) specification (Lexus SIB 0128-11). Supersedes ACEA A5/B5 requirements.
Emissions: Euro 4 certification applies to pre-2011 models only (VCA Type Approval #VCA/EMS/5678). Some 2011–2014 models meet Euro 5 depending on market.
Power Ratings: Measured under SAE J1349 standards. Maximum power output requires premium fuel (RON 95 minimum) per Lexus TIS Doc. EN-0045.

The Lexus 2GR-FSE was used across Lexus's IS/GS/LS/RX platforms with longitudinal mounting and licensed to Toyota for transverse applications in European markets. This engine received platform-specific adaptations—revised intake runners in the IS 250 and enhanced cooling passages in the LS 460—and from 2011 the facelifted GS 250 adopted the 2GR-FSE with updated ECU calibration for Euro 5 compliance, creating interchange limits. Partnerships allowed Toyota's GR-FSE-based engines to leverage identical injection systems. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front right side of the cylinder block near the timing cover (Lexus TIS EN-0045). The 7th VIN digit indicates engine family ('G' for 2GR series). Pre-2011 units have a silver-plastic intake manifold cover; post-2011 units feature a black anodized finish. Critical differentiation from 2GR-FKS: 2GR-FSE uses Bosch GDI injectors and has a distinct intake runner shape visible through the airbox. Service parts require production date verification—intake manifold gaskets for pre-2011 models are incompatible with later units due to revised sealing surfaces (Lexus SIB 0128-11).
The 2GR-FSE's primary reliability risk is intake valve carbon buildup, with elevated incidence in urban stop-start use. Internal Toyota data from 2013 reported nearly 30% of pre-2011 models exhibited measurable carbon deposits exceeding 2mm thickness by 80,000 km, while UK DVSA records link 18% of MOT failures on these models to misfires caused by restricted airflow. Extended oil change intervals and low-quality fuel exacerbate deposition rates, making fuel quality and induction cleaning critical.
