Will Sea Foam clean injectors and help inefficient fuel consumption? [SOLVED]

Thanks for the question, Lowell! I’d try High Mileage Motor Treatment. It works well to clean up fuel injectors, along with the entire fuel system. If the fuel efficiency problem is caused by fuel residues or deposits, High Mileage will help clean it up.

Here’s what I’d do: wait until the tank is low (1/4 -1/8 tank), and add the whole 16 oz can. Then, drive for as long as possible on that tank before refueling. It’s safe to add a high concentration like that and it works very well for cleaning fuel residues and deposits.
