ACDelco 10-3012 - Gasoline Fuel System Treatment Plus - 12 oz

Signs of Wear & Troubleshooting

• Fuel system service is possibly required when the vehicle is hesitating, having trouble starting, achieving sub-par gas mileage, operating sluggishly, and/or providing poor overall performance.
• Faulty fuel injectors in particular can cause a number of issues, including abrupt engine power, engine misfire, rough idling, fuel leakage, and reduced fuel economy.
• Fuel injectors (particularly the injector nozzles) are in an environment where tremendous heat is generated. The burning of fuel can leave hardened carbon deposits on piston valves and fuel injector nozzle heads that interfere with the spray pattern and flow of fuel. The preceding issues, especially when multiple issues are encountered at the same time, are indications that this and other forms of contamination have occurred.
• Although significant repair of fuel system components may be required in serious cases, fuel system additives are often an excellent solution for nagging problems.

Good Maintenance Practices

• 1 oz. of this product treats 1 gallon of fuel. Add the number of ounces of fluid equal to the capacity in gallons for the fuel tank and then fill the tank. More than one bottle may be necessary to properly treat some vehicles. Minor over-treatment (up to 10%) will have no adverse effects on the engine. Repeat every time the oil is changed.
• The goal of proper fuel system maintenance is to keep the system clean and help ensure the most economical and efficient fuel system life.
• Some of the ways contaminants can be kept out of the system from the onset are by keeping fuel system components, especially fuel transfer equipment like nozzles, tanks, and hoses, free from surface dirt and out of the rain.
• Performing regular fuel system cleaning and maintenance helps remove fuel varnish build-up, intake valve deposits, and cylinder head deposits.
• One of the major goals of fuel system cleaning and maintenance is to maximize fuel economy, which is a huge concern with today's fuel prices. In order to maximize fuel economy and avoid significant, costly fuel system repairs, you should regularly check the tire pressure, stay vigilant with engine tune-ups, regularly check tire wear for signs of poor wheel alignment, and run air conditioning only when necessary. You should also change the oil as required, regularly check cooling system operation, check for dragging brakes, avoid excessive idling, drive at the speed limit, and accelerate moderately from a stop.
