Should I add Sea Foam IC5 Fuel Injector Cleaner to a full tank or low tank of fuel? [SOLVED]

I have about a quarter tank of gas in a 2010 Jeep Compass Sport with 147,000 miles. Do I add the fuel injector cleaner before I fill up my tank or after?

That’s a great question Brittany. Adding IC5 Fuel Injector Cleaner to a lower amount of fuel will create a stronger cleaning concentration. Be sure to drive at least 20 miles before adding fuel.
