Is fuel injection cleaner good for a car?

Answer 1

Modern fuels today contain a fuel injector cleaner so the need to use a commercially available cleaner is less important, unless you are buying cheap fuel. However I do recommend you use a can at least once a year. But the fact is that most cheap fuel injector cleaners you buy today are of little value. Purchase a can of a good FI Cleaner and pour one can in a full tank of fuel at least once a year. Most good cleaners will cost around $6. Seafoam, Techron, Lucas, are 3 great cleaners. I personally use Seafoam, and have had no injector problems at all. It can be purchased at Advance Auto Parts, Walmart, and many other Auto & Marine Parts stores. Follow the directions on the can to the letter.
