Fuel injector cleaner does not hurt anything,but most fuels already have a cleaning additive in their fuel.
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.
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.
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
No its just to clean your injectors the fuel injector cleaner will just go right through the filter it wont do anything to filter.
buy a bottle of fuel injector cleaner to do that job for you
Paint.
I assume you are asking about professional cleaning. Unless you have an injector that is giving you a problem the answer is no. Modern gasolines contain a cleaner to help keep injectors clean. Replace the fuel filter every 36,000 miles. Once a year pour one can of a good fuel injector cleaner in a full tank of fuel. A cleaner such as Seafoam, Techron, or similar product is just good insurance. Avoid the cheap cleaners that you buy for under $2 as they are for the most part worthless.
Go Down to your local part store and by the best fuel injector cleaner for your car.
No. The filter will need to be replaced.
