How to restore fuel consumption after adding fuel additive?
2 Answers
Methods to deal with increased fuel consumption after adding fuel additive: 1. Use genuine fuel additive: If you purchase off-brand or unknown small brands, the materials inside may damage the engine, leading to decreased engine performance and increased fuel consumption. If using fuel additives, it's recommended to choose reputable brands for assurance. Additionally, new cars do not need fuel additives. 2. Vehicle-related reasons: Such as faults in the intake system or fuel injectors. For such issues, it's necessary to visit a professional auto repair shop or 4S store to have a technician inspect and identify the problem before performing targeted repairs.
Last time I added a certain brand of fuel additive, my fuel consumption inexplicably skyrocketed, becoming significantly higher than usual in less than two weeks. I figured it might be due to some ingredient in the additive that didn’t match well with the engine, reducing combustion efficiency. I immediately stopped using it and switched to pure gasoline, running several high-speed trips to burn off any residue. After driving about 300-500 kilometers, the fuel consumption gradually returned to normal levels. I also took the opportunity to check the air filter and found it a bit dirty, so I replaced it with a new one. Extra tip: Fuel additives are meant to clean carbon deposits, but some car models are sensitive and may experience increased fuel consumption. It’s advisable to check the manual for compatibility before use. From now on, I’ve learned my lesson—I’ll test small amounts first to observe the effects.
