If you are talking about a Fuel Injector and fuel system cleaner, yes, I recommend you treat your fuel system at least once a year. I recommend Greased Lightning fuel system cleaner. Neither one is cheap but they are very good. The cheap stuff is worthless.
I have tried the Greased Lightning's Fuel System Treatment and it worked for improving my gas mileage much better then Slick 50, Lucass, and Seafoam combined. It helped solve some of my engine noise and was really easy to use. I would recommend it and would not buy any other product after using this one.
Yes, read the instructions the can. I recommend Seafoam or Techron fuel treatment.
I would recommend not running the engine until the fuel is drained. Any amount of petrol/gasoline in a diesel can cause engine or fuel system damage.
i would not recommend it. that will have your fuel pump at a constant run when the ignition is switched on.
Try a shop bought fuel treatment, have had success but needs a few applications to each tank of fuel.
There have been many oil additives and engine cleaners.There are few oil additives that actually help increase friction modifiers in conventional and synthetic oils.Lucas Oil Fuel Treatment is the best fuel injector cleaner.It includes both injector cleaners and fuel conditioners in one bottle.
You will not know until your engine stops. For this reason fuel filters are just replaced a a set mileage. I recommend every 75,000 miles unless the filter is in the fuel tank. In that case it requires no maintanence.
As long as your fuel treatment contains a detergent. Xtreme Fuel Treatment contains a detergent and a demulisifier and polymerization dispersants to clean injectors, separate water and break up sludge.
the engine fuel is with the robot
A pump that pumps fuel from the fuel tank to the engine.
Fuel System Treatments clean your entire fuel system. They can Reduces emissions, Restores performance, and help protect the environment by reducing hydrocarbons and carbon dioxide by over 60%. I used Greased Lightning's Fuel System Treatment and it Increased my Fuel Mileage! If you use one... I highly recommend Greased Lightning.
Yes it has a carburetor. An engine with fuel injection would be a fuel injected engine.
