The weight of the Hyundai G8AA engine is 230 kg (including attachments). The engine requires high-quality gasoline with an octane rating of AI-98, otherwise it will operate unstably. Additionally, this unit suffers from rapid carbon buildup on the intake valves. Regularly check the condition of the timing belt, as its failure is fatal for the engine. After 100,000 km, the catalytic converters may deteriorate and become clogged with exhaust debris. And the main problem with the engine is the shortage and extremely high cost of spare parts.
