Key item features

  • Advanced Cleaning: This fuel system cleaner utilizes a concentrated blend of high-temp and low-temp detergents to effectively clean injectors, carburetors, valves, and combustion chamber deposits.
  • Enhanced Performance: The treatment improves gasoline stability and reduces the formation of gum and varnish, contributing to a more efficient fuel burn and potentially reducing the need for higher octane fuel.
  • Corrosion Prevention: Designed to exceed expectations, this product not only cleans but also prevents corrosion within the fuel system, ensuring its longevity and optimal function.
  • Simple Application: For most effective treatment of neglected vehicles, one 15-ounce bottle should be used per tank, achieving nearly 100% cleaning efficiency in a single application.
  • Versatile Usage: Suitable for use with oxygenated fuel and safe for continual application, one bottle can treat up to 100 gallons for maintenance, and it includes a synthetic upper cylinder lubricant.
  • Dual Pack: The product is conveniently offered as a 2-pack, with each bottle containing 15 ounces of the complete fuel system cleaner.

I'm a believer in Redline

I had a misfitting and slight popping in my engine.I think it was a bad tank of gas.After burning almost all of the tank,I poured a bottle of Redline in the tank.Then topped the tank off with fresh gas.After burning half the tank,my engine has smoothed out.I'm adding one more bottle of Redline and topping it off today.Was it the Redline or was it just needing to burn off the possible bad gas.It doesn't matter.My plan is to continue using Redline maybe every 3 tanks.Recommend.
