Style: Fuel System Cleaner
Works perfectly for my 2007 Honda Accord and have no issues with my engine. I apply this product once a month and since using I’ve not had my check engine light come back on. Definitely recommend because it’s worth the money and will save you extra money at the mechanic shop.

I purchased a car that had been sitting for a while and noticed some sputtering when accelerating at higher speeds. I ran a bottle of this through with a full tank of gas and by the end of the tank the sputtering was gone!
