Can you get the IC5 Fuel Injector Cleaner in larger bottles? [SOLVED]

Thanks for the question, John! No, unfortunately the 5 oz bottle is the only size we sell.

If you want to treat larger volumes of fuel to clean fuel injectors, we have a 20 oz Truck & SUV size can of Sea Foam Motor Treatment, as well as a 1 gallon jug. You can find both of those at an auto parts store.

If you’re trying to treat large fuel tanks, you could also use a high concentration of Sea Foam Motor Treatment in fuel. Sea Foam Motor Treatment works well to clean fuel injectors. The idea is to add a small amount of fuel (2-4 gallons) and a whole 16 oz can of Sea Foam Motor Treatment. Then, drive until it’s almost empty to give the Sea Foam a chance to clean. The high concentration will do a great job cleaning, and you don’t need to fill the entire tank and treat all the fuel in the tank.
