Wynn's GDI Efficiency Restorer is a product designed specifically for vehicles with gasoline direct injection (GDI) engines.

GDI engines are becoming more common in modern vehicles because they offer better fuel efficiency and performance compared to traditional port-injection engines. However, GDI engines can suffer from carbon buildup on the intake valves over time, which can affect engine performance, fuel efficiency, and emissions.

You should use Wynn’s GDI Efficiency Restorer on vehicles with GDI (Gasoline Direct Injection) engines, which are typically found in:

Hybrid engines with a GDI system.

Some hybrids use a combination of traditional gasoline engines and electric motors, but the gasoline engine often uses GDI technology.

Turbocharged engines.

GDI technology is often used in conjunction with turbocharging for better performance, and these engines are more prone to carbon buildup.

Many newer models from major automakers.

It’s typically added to the fuel tank (check the instructions for the right amount). It is important to follow the recommended dosage for your engine size and to use it according to the manufacturer’s instructions to avoid any potential damage or issues.
Warning:

  • Not for older, non-GDI engines: don’t use this product in vehicles without a GDI engine. It may not provide any benefits and could potentially harm the engine.
  • Ensure it’s compatible: always check if the product is compatible with your vehicle’s specific engine type and configuration.

If you’re unsure whether your vehicle has a GDI engine, you can usually find this information in the owner’s manual, on the engine bay label, or by checking with the manufacturer.
