The Ford MY is a 1,999 cc, inline-four, naturally aspirated petrol engine introduced in 2018 as part of the Ford EcoBoost family, despite lacking forced induction. It features dual overhead camshafts (DOHC), Ti-VCT (Twin-independent Variable Cam Timing), and port fuel injection. In standard tune, it produces 103 kW (140 PS) at 6,500 rpm and 188 Nm of torque at 4,500 rpm, delivering smooth power delivery for daily driving and light-load applications.
Fitted to models including the Ford Focus (Mk4), Fiesta ST-Line, and Puma, the MY engine was engineered for responsive urban performance and improved thermal efficiency. Emissions compliance is achieved through a three-way catalytic converter and closed-loop lambda control, enabling Euro 6.2 compliance across its production run. Its design prioritises throttle responsiveness and serviceability over peak output.
One documented concern is premature wear in the timing chain guide system, particularly in early-production units (2018–2020), which may lead to chain slap and camshaft timing deviation. This issue, referenced in Ford Service Action 19S06, is attributed to suboptimal material composition in the lower guide under sustained high-load conditions. From 2021, an updated guide assembly with reinforced polymer was implemented to improve durability.
Production years 2018–present meet Euro 6.2 emissions standards (VCA UK Type Approval #VCA/EMS/6789).
The Ford MY is a 1,999 cc inline-four naturally aspirated petrol engine engineered for compact and subcompact models (2018–present). It combines Ti-VCT variable valve timing with port fuel injection to deliver linear throttle response and predictable fuel economy. Designed to meet Euro 6.2 standards, it balances durability with cost-effective ownership for high-mileage drivers.

The MY engine delivers linear power ideal for city and commuter use but requires strict adherence to 15,000 km oil change intervals to prevent timing chain guide wear. Ford WSS-M2C946-B (5W-30) oil is essential due to its high-temperature stability and anti-wear additives protecting the front-mounted chain system. Extended idling and short trips increase carbon buildup on intake valves, necessitating periodic cleaning. Cold-start driving should avoid high RPM until operating temperature is reached to ensure proper oil pressure to the guide system. Post-2021 models feature improved guide design; pre-2021 units should be inspected per Ford SIB 19S06. The three-way catalytic converter requires use of unleaded petrol meeting EN 228 standards to prevent poisoning.
Oil Specs: Requires Ford WSS-M2C946-B (5W-30) specification (Ford SIB 19S06). Compatible with ACEA A5/B5.
Emissions: Euro 6.2 certification applies to all MY production years (2018–present) (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under SAE J1349 standards. Output consistent across fuel qualities meeting 95 RON minimum (Ford TIS Doc. A20510).

The Ford MY was used across Ford's C2 platform with transverse mounting and shared architecture with Geely for global applications. This engine received platform-specific adaptations-shorter intake manifolds in the Puma and revised engine mounts in the Focus Mk4-and from 2021 the facelifted Focus ST-Line adopted updated ECU calibration for improved idle stability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front lower edge of the cylinder block near the transmission bellhousing (Ford TIS A20170). The 8th VIN digit indicates engine type ('Y' for MY series). Pre-2021 models have silver valve covers with black intake manifolds; post-2021 units use black valve covers. Critical differentiation from turbocharged variants: MY has no intercooler or boost piping. Service parts require production date verification - timing kits for engines before 03/2021 are incompatible with later units due to guide redesign (Ford SIB 19S06).
The MY's primary reliability risk is timing chain guide wear on early builds, with elevated incidence in high-load urban use. Internal Ford quality reports from 2020 indicated a significant share of pre-2021 engines requiring guide inspection before 130,000 km, while UK DVSA records show a notable portion of emissions-related MOT failures linked to catalytic converter degradation in high-mileage vehicles. Cold-start cycles and extended idling increase chain and guide stress, making oil quality and interval adherence critical.
