Which outcome occurs when a gasoline direct injector (GDI) engine experiences repeated exposure to high sulfur fuel?

💡 Explanation

When GDI engines use high sulfur fuel, incomplete combustion causes sulfur compounds that polymerize on injector nozzles because heat soak carbonizes residual fuel, leading to deposits and distorted spray patterns. Therefore, injector deposits result, rather than catalytic converter failure, knocking, or ring wear which involve different mechanisms and longer timescales.
