Do I need to use a fuel cleaner on a regular basis? Why? Or why not?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Marcia, Yes, I recommend AMSOIL Fuel P.I. The reason you should use a fuel cleaner is because over time carbon will form on your valves, combustion chamber, and the head of your fuel injectors. Decreasing power, fuel economy, and performance. AJ Pierce

Donna Burmeister, Service Manager at Classic Nissan Some manufacturers don*t recommend them and some do. You*ll have to consult your dealer.

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Marcia, Personally I'm not impressed by the fuel additives. If you really want to have this service done, I would recommend going to the dealer and having a top engine fuel cleaning done. This is not added into the tank, but a process which connects directly to the fuel rail and runs top engine cleaner through the engine. Much more efficient. You may want to do this every couple of years, depending on how your engine is running. When they do this service you also need to change your oil afterwards. Hope this helps.
