How to Use Fuel Injector Cleaning Chemicals

Use fuel injector cleaning chemicals to clear injectors of deposits from fuel and its additives. The products are made with concentrated detergents to break up minerals that form and clog the tiny nozzles on fuel injectors. That reduces the flow of fuel to the engine cylinder, causing hard starts, sputtering and knocks.
A fuel injector cleaner can cure the problem. Auto makers have improved injector design, but at the same time gasoline quality has declined. Although most major petrol companies add detergents to avoid deposits in fuel systems, sometimes injectors still get clogged.

Difficulty: Easy

Instructions

1. Choose a product. Find a cleaner with ingredients you trust that's formulated to work as you desire. Some use lubricants, and many are designed to work on the entire fuel system. Fuel injector cleaners are made by Pennzoil, STP, Gumout, Marvel Mystery Oil, Gunk, Lucas and others.

2. Read and follow label directions. A bottle of fuel injector cleaner will specify how many gallons of gas to mix it with. Each product is different. As such, each will recommend differing intervals for follow-up treatments.

3. Check your fuel level. Start the car and look at the fuel gauge. If your car has a 15-gallon tank and the gauge is at the 1/2 mark, then you only have 7 1/2 gallons in the tank. Add more fuel if necessary to meet the requirements of the product you're using.

4. Pour fuel injector cleaner into the gas tank. The detergents will clean injectors as you drive.

Tips & Warnings

• Consult a certified mechanic if sputtering and knocks do not stop after using a fuel additive. The injectors may need a professional pressure cleaning, or the engine may be experiencing a different problem.
• Never add fuel injector cleaner to a tank with low fuel. The detergent can loosen sediment from the gas tank and the rest of the fuel system, actually causing a clog in the injectors.
