What about Fuel
Economy? 
You may see a lot of after-market products that make elaborate claims on improved fuel economy. Be aware that it can be easy to claim fuel economy shown in a laboratory. It is very difficult to demonstrate fuel economy in the field in modern engines.
Very large fleet tests with a wide range of vehicles representative of popular models, a range of representative driving cycles, multiple duplicate tests and very extensive controls are needed in order to conduct a proper evaluation. Engine type, fuel, driving cycle, vehicle to vehicle variations, and individual driving style further affect fuel economy.
Consumers who have severely clogged fuel injectors would see a measurable improvement in fuel economy after treatment with Havoline Performance Plus Fuel System Cleaners.
