    After 3 years of diagnostic experience with French cars like Peugeot and Citroen in Israel i learned that time enables impurities deposits in the gas tank. Now I own a 2015 Prius c., 91000 mi.

    Because I don't have the standard professional testing equipment for fuel injectors pressure, do u think that due to excessive RPM engine noise when i accelerate, should I clean periodically the gas tank and fuel injectors with some efficient injectors cleaning liquid??

    What name brands do u suggest??
    Thanks

    I’ve used Chevron Techron for many years with good results. It once cleaned the flutes on 1985 Camry intake valves that acted as lost compression. I’m not sure of the availability where you are.

    The roar under full acceleration is pretty normal on a 2015. I have one.

    Best of luck,

    The gasoline supply in the United States is much cleaner than in other parts of the world.

    There's very little need for fuel cleaners in cars that have spent their lives burning US gasoline.

    It is quite normal for a Prius c to wind up to full RPM during hard acceleration; this is to be expected in Los Angeles traffic.

    I do not anticipate that a fuel system cleaning will have any noticeable effect.
