Take some time to research the ingredients used in the cleaner you are interested in purchasing. Look for products that contain detergents and additives such as PEA (polyetheramine) which is known for its effectiveness in removing deposits.

4. Price

While price should not be the sole determining factor, it is important to consider how much you are willing to spend on a high mileage fuel system cleaner. Keep in mind that some products may require multiple treatments for maximum effectiveness.
