If the engine is not cleaned properly, engine deposits accumulate on critical engine parts and block passageways in the same way plaque clogs arteries.
The restricted fuel and air flow lead to decreased power and fuel economy. Although it's difficult to see what is happening inside your car's fuel system, there are several "symptoms" indicative of engine-deposit problems.
Engine Deposit Symptoms
Fuel-injector deposits obstruct fuel flow and thus upset the fuel/air mixture. When this occurs, you may experience hesitation or stumble during acceleration, loss of power, or increased emission of hydrocarbons and carbon monoxide.
Intake-valve deposits can absorb fuel during engine warm-up and cause the fuel/air ratio to "thin out." The result is poor drivability, reduced power and increased emissions.
Combustion-chamber deposits can lead to auto-ignition of the fuel/air mixture. When this happens, you may hear a knocking or pinging sound. You might also notice poor acceleration and increased emissions of nitrogen oxides.
Corrosive sulfur deposits can develop from long-term exposure to low-grade fuel or an off-speculation batch of high-sulfur gasoline. Sulfur corrosion may result in erratic operation or failure of the vehicle's fuel-sending unit, which leads to inaccurate readings on the fuel gauge. This inaccuracy can cause a driver to unexpectedly run out of fuel.
Treating The Symptoms
Is your car's fuel system in good shape? It's hard to tell but easy to fix and maintain. Treating one tankful of gasoline every 3,000 miles with a fuel-system cleaner-like Chevron's Techron Concentrate Plus-can improve the health of the car's fuel system as you drive.
Fuel-system cleaners not only protect your vehicle's lifeline but can restore engine power and maximize fuel efficiency. The use of fuel-system cleaners is a cost-effective, do-it-yourself way to help prevent fuel-related drivability problems before they start.
