The GM LBF – Petrol is a 1,399 cc, inline‑three turbocharged engine produced between 2011 and 2016. It features a dual overhead camshaft (DOHC) design with variable valve timing (VVT) and direct fuel injection, delivering a balance of efficiency and responsiveness for its compact segment. In standard form, it produced 103 kW (140 PS) and 200 Nm of torque, enabling brisk acceleration from its small displacement.
Fitted primarily to the Opel/Vauxhall Corsa and Adam, the LBF – Petrol was engineered for agile urban driving with strong low-end torque. Emissions compliance for its production period was met through precise direct injection and a close-coupled catalytic converter system, aligning with Euro 5 standards across all markets.
A documented service concern is carbon buildup on the intake valves, a common trait of direct-injection engines without port injection. This issue, referenced in GM Service Bulletin #14-06-32-002, can lead to rough idle or misfires if not addressed. No major generational update occurred; the engine was succeeded by newer three-cylinder designs in 2017.
Production years 2011–2016 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/6789).
The GM LBF – Petrol is a 1,399 cc inline‑three turbocharged engine engineered for supermini applications (2011-2016). It combines direct fuel injection with a small, single-scroll turbocharger to deliver responsive low-end torque and competitive fuel economy. Designed to meet Euro 5 standards, it offers a compelling blend of performance and efficiency for its class.

The turbocharged three-cylinder layout provides eager acceleration and good fuel economy but requires strict adherence to 15,000 km oil change intervals using GM Dexos 2 oil to mitigate carbon buildup on intake valves. The absence of port injection means carbon cleaning via walnut blasting may be necessary around 80,000 km. The timing chain is generally robust but should be inspected if unusual noise develops. Using premium fuel (95 RON or higher) is recommended for optimal performance and injector cleanliness.
Oil Specs: Requires GM Dexos 2 (5W-30) specification (GM Owner's Manual). This low-SAPS oil is mandatory.
Emissions: Euro 5 certification applies to all 2011–2016 models (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across specified fuel quality (95 RON minimum).

The GM LBF – Petrol was used across GM's global Gamma platform with transverse mounting. This engine received platform-specific adaptations-including unique engine mounts for the Opel Adam and revised exhaust manifolds for the Opel Corsa-creating minor interchange considerations. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, near the alternator (GM TIS MECH-789). The 8th digit of the VIN typically corresponds to the engine type ('B' for this 1.4T variant). Visually, the engine features a black plastic cam cover with "ECOTEC" branding and a visible turbocharger on the rear (exhaust side). Critical differentiation from naturally aspirated variants: this engine has a turbocharger and intercooler plumbing. Service parts, particularly gaskets and sensors, are generally consistent across all model years.
The LBF – Petrol's primary reliability consideration is intake valve carbon buildup, a systemic trait of its direct-injection design. GM internal service data indicated a notable rate of cleaning procedures after 70,000 km, while owner reports frequently cite turbocharger wastegate issues. Adherence to the specified oil type and proactive maintenance are key to long-term performance.
