Fuel System Additives

Fuel System AdditivesA dirty fuel system can affect your vehicle's performance. Over time your vehicle builds up sulfur deposits and clogs your intake, exhaust, and other ports inside your engine. Therefore, leading to excess pollution, less fuel efficiency or reduced power when stepping down on your gas pedal. At Auto Barn, we carry fuel treatments, fuel cleaners, octane boosters, fuel conditioners, and fuel stabilizers for gas or diesel engines by STP, Lucas Oil, Gunk Engine Cleaner, Lubro-Moly, Chevron Techron, Gumout, or Lubegard.
