How to Use Fuel Injector Cleaner?
2 Answers
The method of using fuel injector cleaner is as follows: 1. Turn off the engine and open and secure the hood; 2. Remove the fuel pump fuse of the vehicle to be cleaned; 3. Add combustion chamber cleaner or fuel injector cleaner to the fuel system no-disassembly cleaning equipment; 4. Connect the external air source to the air interface of the equipment, and set the fuel pressure according to the technical requirements of the vehicle to be cleaned; 5. Hang the equipment with added fuel injector cleaner and pressurized on the front hood of the vehicle to be cleaned; 6. For vehicles with a return pipe, remove the return pipe and seal it; 7. Place a cloth under the fuel pipe, remove the fuel inlet pipe, and connect it to the fuel injector of the fuel system no-disassembly cleaning equipment; 8. Open the fuel flow switch under the equipment, check for any leakage, and start the engine of the vehicle to be cleaned after confirming no issues; 9. After cleaning for about 30 minutes, the cleaning is completed, and remove the cloth under the fuel inlet pipe; 10. Restore the fuel pipe of the vehicle to be cleaned and plug in the fuel fuse; 11. Check if the installation is correct, start the vehicle to idle for 3 to 5 minutes, increase the speed to 2000 rpm, and check for any fuel pipe leakage.
Using fuel injector cleaner is actually quite simple. When I first started driving, I didn't know how to do it either, but I learned later. The usual procedure is to do it before refueling: first park the car at the gas station, make sure there's about 1/4 tank of fuel left—not too full nor too empty. Then open the cleaner bottle cap and pour the specified amount directly into the fuel tank as indicated on the bottle. After pouring, close the fuel cap, start the car, and drive normally. Drive a few hundred kilometers to let the cleaner circulate. Be careful not to overuse it—one can is enough, as too much might damage the fuel system. I usually use it every 5,000 kilometers, and I've noticed a significant reduction in fuel consumption and smoother acceleration. The cleaner removes carbon deposits from the fuel injectors, preventing uneven fuel spray that can cause shaking or power loss. Long-term use can also extend engine life. For beginners, I recommend choosing well-known brands like 3M—don't go for cheap, no-name products.
