The MG 1.5T eGT – Petrol (SAIC) is a 1,490 cc, inline‑four turbocharged petrol engine produced since 2017. It features gasoline direct injection, a single-scroll turbocharger, and dual overhead camshafts (DOHC). This powertrain, developed by SAIC Motor, delivers a balance of performance and efficiency, with outputs typically around 124 kW (169 PS) and 250 Nm of torque.
Fitted primarily to the MG ZS and MG HS SUVs, the 1.5T eGT was engineered for responsive urban driving and relaxed highway cruising. Emissions compliance for European markets is achieved through technologies like a three-way catalytic converter and oxygen sensors, allowing the engine to meet stringent Euro 6 standards.
One documented area for attention is the potential for carbon buildup on intake valves, a common trait of direct-injection petrol engines without auxiliary port injection. This is addressed in routine maintenance schedules outlined in SAIC service documentation. Continuous software updates have refined turbocharger control and fuel mapping over the production run.
All production years (2017–Present) for vehicles sold in the UK meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/MGZS20).
The MG 1.5T eGT – Petrol (SAIC) is a 1,490 cc inline‑four turbocharged petrol engine engineered for compact SUVs (2017-Present). It combines gasoline direct injection with a single-scroll turbocharger to deliver brisk acceleration and efficient cruising. Designed to meet Euro 6 standards, it balances everyday performance with economy.

The turbocharged setup provides strong mid-range pull ideal for overtaking but requires adherence to 15,000 km or 12-month oil change intervals to maintain turbo and chain longevity. ACEA C2/C3 5W-30 oil is critical for its low-SAPS formulation, protecting the emissions system. Direct injection necessitates periodic intake valve cleaning (recommended every 60,000 km) to prevent power loss and rough idle. The engine's calibration prioritizes smoothness; aggressive driving may trigger earlier DPF regenerations in mild-hybrid variants. Software updates for ECU and TCU are available via SAIC dealers to optimize performance.
Oil Specs: Requires ACEA C2/C3 5W-30 specification (SAIC SB-LUB-001). Compatible with API SP.
Emissions: Euro 6 certification applies to all UK-market models (VCA Type Approval #VCA/EMS/MGZS20). Real-world emissions monitored under WLTP.
Power Ratings: Measured under ISO 1585 standards. Output consistent across model years (SAIC PT-MG-15T-01).

The MG 1.5T eGT – Petrol (SAIC) was used across MG's compact SUV platforms with transverse mounting. This engine received platform-specific adaptations-unique engine mounts and exhaust routing for the ZS versus the HS-but no major facelift revisions have created significant interchange limits to date. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the timing cover (SAIC TIS ENG-ID-01). The 8th VIN digit typically corresponds to the engine type ('T' for 1.5T petrol). Visually, the engine features a black plastic intake manifold and a centrally mounted turbocharger. Critical differentiation from the 1.5L naturally aspirated engine: the 1.5T has a visible turbocharger and intercooler piping. Service parts are generally consistent across ZS and HS applications, but intake manifolds and some ancillary brackets differ; always verify part numbers against the specific model and VIN.
The 1.5T eGT's primary maintenance focus is preventing carbon buildup on intake valves, a known characteristic of its direct-injection system. SAIC service schedules recommend proactive cleaning, while UK DVSA data shows no elevated failure rates for core components. Extended oil intervals or use of incorrect oil grades can accelerate wear on the turbocharger and timing chain, making adherence to service specifications critical.
Analysis derived from SAIC technical bulletins (2017-2024) and UK DVSA failure statistics (2018-2023). Repair procedures should follow manufacturer guidelines.
