The Toyota 1UR-FE is a 4,608 cc, 90° V8 naturally aspirated petrol engine produced between 2006 and 2022. It features an aluminium block and heads, dual overhead camshafts, and Dual VVT‑i for broad, refined power delivery. In standard form it delivered 234–284 kW (318–386 PS) and 460–530 Nm of torque, engineered for flagship SUVs and luxury sedans prioritizing smoothness and effortless performance.
Fitted to models such as the Land Cruiser 200 Series (URJ200), Lexus LS 460 (USF40), and Tundra (GSK30), the 1UR-FE was designed for drivers seeking quiet, authoritative power for highway cruising, towing, and off-road capability. Emissions compliance was achieved through precise electronic fuel injection and advanced catalytic converters, meeting Euro 4 and Euro 5 standards depending on model year and market.
One documented engineering characteristic is the potential for excessive oil consumption in high-mileage examples, a concern noted in Toyota's Technical Service Bulletin (TSB) EG011-08, often linked to piston ring wear or Positive Crankcase Ventilation (PCV) system inefficiency. Toyota addressed this with revised piston ring designs and updated PCV components in later production years.

The DOHC design with Dual VVT-i provides a smooth, authoritative powerband ideal for heavy vehicles but requires using the correct ILSAC GF-5 specification oil to prevent excessive oil consumption and sludge. The chain-driven timing system is very durable with minimal maintenance. Toyota TSB EG011-08 details specific diagnostic procedures for oil consumption, often recommending piston ring replacement or PCV system cleaning in high-mileage engines. Regular oil changes every 10,000 km are critical for longevity.
Oil Specs: Requires API SM/SN or ILSAC GF-5 specification oil (Toyota TSB EG011-08). Modern API SP oils are suitable upgrades.
Emissions: Euro 4 certification applies to 2006-2009 models; Euro 5 applies to 2010-2022 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under JIS D 1001 standards. Output varies by model application and year (Toyota Group PT-2018).

The Toyota 1UR-FE was used across Toyota's Land Cruiser and Tundra platforms, as well as Lexus luxury sedans, with longitudinal mounting and was not licensed to other manufacturers. This engine received platform-specific adaptations-reinforced mounts for the Land Cruiser and unique intake manifolds for the Lexus LS-but no major facelift revisions affecting core compatibility occurred during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the left cylinder bank, near the timing cover (Toyota Workshop Manual RM1125U). The engine bay VIN plate will also list the engine code. Visual identification: Aluminium block, dual cam covers with "VVT-i" logo, coil-on-plug ignition system. Critical differentiation from 3UR-FE: 1UR-FE is 4.6L (4608cc), while 3UR-FE is 5.7L (5663cc). Engine management ECUs and some ancillary components are not interchangeable.
The 1UR-FE's primary reliability concern is excessive oil consumption in high-mileage examples, with elevated incidence in vehicles exceeding 200,000 km. Toyota TSB EG011-08 documents this as a service issue, while owner reports frequently cite water pump leaks and ignition coil failures. Adhering to strict oil change schedules and using correct lubricants make preventative maintenance critical.
