Carbon Buildup
Intake valves regulate the delivery of fuel and air into the combustion chamber. When carbon deposits build up on the base of valves, they act like sponges, soaking up fuel. This means that less fuel than expected enters the combustion chamber, disrupting the fuel/air mix and hurting performance.
Fuel system cleaning services provide excellent benefits to your vehicle. From maximizing fuel economy to reduced vehicle emissions, a clean fuel system restores performance and improves drivability.
Corrosion
To help reduce emissions, most modern gasoline contains ethanol, a solvent that's naturally attracted to water. When water enters the fuel system from humidity or condensation, ethanol absorbs it. Then, once it reaches its saturation point, the ethanol separates from gasoline and settles at the bottom of the gas tank.
From there, ethanol and water begin to attack the metal surfaces of the fuel system. Oxygen dissolved in ethanol weakens the outer layer of metal parts, while water causes them to rust and corrode.
