The Root Cause: Poor Fuel Quality Triggers Multiple Engine Faults

For overseas Toyota Levin 1.2T owners, inferior fuel is a hidden hazard to the precision fuel system. Low-quality fuel will lead to carbon deposit accumulation inside the engine. Over time, carbon build-up further causes spark plug clogging and fuel injector clogging.

As the fault condition worsens, drivers will notice obvious engine abnormal noise. If the problem is left untreated, the engine will suffer irreversible damage, affecting vehicle power and driving safety.
