STP does a fine job and is moderately priced.
I highly recommend you use Seafoam or Techron once each year. They are not cheap but quality rarely is.
buy a bottle of fuel injector cleaner to do that job for you
Diesel fuel injector cleaner will not hurt your unleaded gas motor. The diesel fuel injector cleaner is basically the same as your unleaded injector cleaner.
Fuel injector cleaner does not hurt anything,but most fuels already have a cleaning additive in their fuel.
Pouring the injector cleaner down the throttle body won't clean the injectors. You need to add the injector cleaner to the fuel tank for it to help you. Read the instructions on the container of injector cleaner.
in the fuel tank
Fuel injector cleaner is a liquid which one puts in their gas tank to clean the engine and improve fuel performance. Fuel injector cleaner can be purchased at Canadian Tire, Walmart, and at many gas stations.
no i dont think you can use diesel fuel injector cleaner in gas engines
Modern fuels have a fuel injector injector cleaner built into them. However I do recommend you use a good fuel injector cleaner such as Seafoam or Chevron Techron once a year.
you could add gas treatment liquid to your gas tank or you could buy the fuel injector cleaner tool and run the system with fuel injector cleaner which is alot faster. other then tht you could take each fuel injector out and spray carb clener through the fuel injector until you see nice spread out spray coming out.
No its just to clean your injectors the fuel injector cleaner will just go right through the filter it wont do anything to filter.

Go Down to your local part store and by the best fuel injector cleaner for your car.
