How is the durability of the LTG engine?

LTG 2.0T belongs to the third-generation Ecotec series from General Motors. This engine was awarded the title of Ward's 10 Best Engines in 2013. Below are the specific details: 1. Main technologies: The key technological features of this engine include the adoption of a modular balance shaft, piston spray cooling, air-cooled intercooler system, variable displacement oil pump, SIDI direct injection, variable valve timing for intake and exhaust, and a twin-scroll turbocharger. The LTG 2.0T engine was first installed in the Cadillac ATS-L and Buick Envision in 2014, making it the top competitor to Volkswagen's EA888 at the time. 2. Turbocharging technology: The 2.0L LTG engine uses a twin-scroll single turbocharger, and the turbocharger's cooling method employs the traditional oil-cooled approach. The biggest advantage of the twin-scroll single turbocharger is its ability to separate the exhaust gases from adjacent cylinders based on the engine's firing order. This separation reduces the interference of exhaust gas flow on the turbine blades, allowing the engine to maintain high turbo efficiency even at low RPMs.
I feel the LTG engine's overall durability is quite solid, but it depends on how you use and maintain it. I've seen many owners drive over 100,000 kilometers with it still running normally. The key is to change the oil and filters regularly, recommended every 5,000 to 7,500 kilometers, and avoid using low-quality oil products, otherwise the piston rings can wear out easily, leading to oil burning. Early models had some minor issues, such as turbocharger overheating causing vibrations, but later GM optimized the design and improved the cooling system. Compared to Japanese engines in the same class, it might be slightly inferior in long-term reliability, but it offers more robust power output, making it suitable for daily driving. Overall, its durability is above average, and with proper maintenance, the average lifespan can exceed 150,000 kilometers. Just don't ignore minor symptoms like unusual noises or dropping oil levels.
