Fuel Injector Cleaners

Fuel injector cleaners are liquid solvents that can be used to improve your car’s performance. They work by cleaning out any residue in the fuel system and will help your engine run smoothly. Depending on which fuel your vehicle runs on, you can choose diesel injector cleaner or petrol injector cleaner. Simply pour injector cleaner into the fuel tank when it is nearly empty to achieve optimal results.
