I have a 2016 Chevy Spark with about a 9 gallon gas tank….the IC5 Concentrated Fuel Injector Cleaner I have says that it “treats up to 25 gallons.” Does that mean I can still pour the whole 5.25 fl oz into my 9 gallon tank or should I only put in about 1/2 of it?
Good question, Cindy. You can go ahead and add the entire bottle of IC5. It’s perfectly safe to add that amount to 9 gallons. In fact, the higher concentration will do a good job cleaning.
