GDi engines are an amazing feat of engineering, they are powerful, fuel efficient, and if cared for properly durable. The direct inject gasoline engine differs from previous fuel injected engines in that the injectors are located in the combustion chamber (much like a diesel). Much like a diesel, direct injection works under extremely high fuel pressure. The downfall to direct injection is the are highly prone to carbon buildup, injector tips can become covered in carbon inhibiting their ability to transfer fuel to the combustion chamber, as well intake valves can build up carbon which can reduce compression, and restrict airflow, all this translates to decreased fuel economy, power and in long term durability. Sadly most consumers are not educated on how to maintain a direct inject engine. We at 5-Star Lexington carry the products to care for your GDi engine
