it's 5$ a bottle here in Fl....the Fuel System Cleaner is 8.95-10.00 depending on where you get it...I've never looked at the price of thier Diesel cleaner. Does their Fuel System Cleaner work? It seems to be good for a injector cleaner..and I feel alittle better using it vs some of the other bottles out there in the cleaner aisle. Since Cleaners range from 3.00-20.00depending on brand/type Redline is a mid-price range product..not the cheapest like STP or Gumout nor the most expensive like Slick50 |
