The Ford LSE is a 1,999 cc, inline — four petrol engine produced between 2018 and 2023. It belongs to Ford's EcoBoost family, featuring direct fuel injection, turbocharging, and port fuel injection (dual injection) to enhance efficiency and reduce carbon buildup. With a balanced design and optimized weight, it delivers 147 kW (200 PS) and 320 Nm of torque, making it ideal for performance — oriented compact and mid — size vehicles requiring strong low — end pull and responsiv…
Production years 2018–2023 meet Euro 6d-Full standards .
The Ford LSE is a 1,999 cc inline-four turbocharged petrol engine engineered for performance-oriented mid-size vehicles (2018–2023). It combines direct and port fuel injection with a low-inertia turbocharger to deliver strong low-end torque and refined drivability. Designed to meet Euro 6d emissions standards, it balances sporty performance with environmental compliance and long-term reliability.

The Ford LSE was used across Ford's C/D-segment platforms with transverse mounting. This engine received platform-specific adaptations-shortened exhaust manifolds in the Edge ST-Line and revised intake routing for packaging-and from 2021 the facelifted Focus ST adopted updated high-pressure fuel pump designs, creating 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The LSE offers strong performance for its size, but early models (2018-2020) showed higher HPFP failure rates under aggressive use. Later revisions (post-2021) improved pump durability with better materials and cooling, making well-maintained examples durable. Regular oil changes with Ford-spec fluid (5W-30 WSS-M2C946-B) and proper warm-up routines significantly extend engine life.
Key issues include high-pressure fuel pump wear (especially on pre-2021 units), intake valve carbon buildup from direct injection, coolant leaks from the thermostat housing, and cold-start timing chain rattle. These are documented in Ford service bulletins and technical updates, with OEM fixes available for most concerns.
The LSE 2.0L turbo petrol engine was used in the Ford Focus ST and Edge ST-Line models from 2019 to 2023. It was offered in 200 PS trim across both generations, with post-2021 models receiving updated fuel pumps. No other Ford models or licensed applications used this specific engine variant.
Aftermarket ECU tuning is common on the LSE platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In the Ford Focus ST (200 PS), combined fuel consumption is approximately 7.1 L/100km (~40 mpg UK). Real-world urban driving may see 8.5–10.0 L/100km (~28–33 mpg), while highway cruising can achieve sub-6.5 L/100km. Driving style and transmission type significantly affect economy, with manual variants being most efficient.
Yes, the LSE is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal damage. Because the chain is front-mounted and tensioned hydraulically, maintaining correct oil pressure and using the specified viscosity is essential to prevent timing issues.
Ford specifies WSS-M2C946-B (5W-30) synthetic oil for the LSE engine. This low-SAPS formulation is critical for turbocharger protection and deposit control in the dual-injection system. Oil should be changed every 15,000 km or annually, with more frequent changes recommended for severe driving conditions.
