The Lexus 3GR-FSE is a 2,994 cc, 60° V6 petrol engine produced between 2005 and 2013. It features dual overhead camshafts (DOHC), 24 valves, and Toyota's D-4S direct and port fuel injection system. This technology enables strong, linear power delivery with improved fuel efficiency and reduced carbon buildup.
Fitted to models such as the GS 300 (GRS190) and IS 300 (GSE21), the 3GR-FSE was engineered for refined performance and quiet operation. Emissions compliance was achieved through precise fuel metering and a sophisticated engine management system, meeting Euro 4 standards across its production run.
One documented concern is carbon accumulation on intake valves, a known characteristic of early direct-injection engines without sufficient port injection contribution. This issue, addressed in later D-4S iterations, can lead to rough idle or hesitation. Toyota service procedures recommend periodic intake cleaning for optimal performance.
Production years 2005–2013 meet Euro 4 standards (EU Regulation (EC) No 715/2007, Annex I).
The Lexus 3GR-FSE is a 2,994 cc V6 petrol engine engineered for executive sedans (2005-2013). It combines DOHC 24-valve architecture with D-4S direct and port injection to deliver smooth, responsive power. Designed to meet Euro 4 standards, it balances performance with refined operation.

The D-4S system provides smooth, linear power but requires periodic intake valve cleaning to prevent carbon buildup, a characteristic of its early direct-injection design. Using high-quality, low-ash oil (5W-30) is recommended to protect the VVT-i system and reduce deposits. The chain-driven timing system is generally robust but should be inspected if unusual noise is detected. Fuel quality meeting EN 228 standards is advised for optimal injector performance and emissions control.
Oil Specs: Requires Toyota Genuine Motor Oil 5W-30 or equivalent meeting API SM/ILSAC GF-4 (Toyota Owner's Manual GSE21).
Emissions: Euro 4 certification applies to all production years (2005-2013) (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under SAE J1349 standards. Output figures are consistent across documented model applications.

The Lexus 3GR-FSE was used across Toyota/Lexus's GRS/GSE platforms with longitudinal mounting. This engine received platform-specific adaptations-such as revised engine mounts and exhaust manifolds for the GS 300 versus the IS 300. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side cylinder block, near the exhaust manifold (Toyota TIS RM1001U). The 4th and 5th digits of the VIN typically indicate engine type ('GR' for 3GR series). Visually, the engine features a black plastic intake manifold with 'D-4S' branding and dual fuel rails. Critical differentiation from the 2GR-FSE: The 3GR has a 3.0L displacement (vs. 3.5L) and produces less power. Service parts, particularly intake manifolds and ECUs, are specific to the 3GR-FSE and not interchangeable with other GR-FSE variants.
The 3GR-FSE's primary reliability consideration is intake valve carbon buildup, a common trait of early direct-injection engines. Toyota service data indicates this can lead to drivability issues if neglected, while the VVT-i system is generally robust. Regular oil changes and periodic intake cleaning are critical for long-term smooth operation.
