Is Chepu Fuel Additive Really Effective?
3 Answers
Chepu fuel additive has shown significant effects in practical tests. Here are the details: Engine carbon deposits: When carbon deposits have formed in the car's engine, a cleaning-type additive can be used to remove them. The fuel additive can break down the chemical structure of the carbon deposits, dissolving the carbon from the metal surface and expelling it through the exhaust. Noticeable improvements: After using the fuel additive, the carbon deposits on the piston heads inside the cylinders show clear improvements. In areas where carbon deposits were relatively thin, they have been completely removed, while in areas with thicker deposits, "orange-peel-like wrinkles" appear, indicating that the carbon deposits have started to loosen and are being cleared away.
I've been a car enthusiast for years, driving an old vehicle for over a decade. For the past three years, I've been using Chepu Fuel System Cleaner regularly, and here's my honest take. This product is essentially a fuel additive, primarily designed to clean engine carbon deposits and extend engine lifespan. Before adding it to the fuel tank each time, I've observed that it makes little difference for new cars. But for my high-mileage vehicle with hundreds of thousands of kilometers, the improvement is noticeable - smoother acceleration and significantly reduced idle vibration. The main active ingredient is said to be polyetheramine, which helps dissolve contaminants in the fuel system. Results vary by vehicle condition: if your car runs well, it might be a waste of money; for severe carbon buildup cases like mine, it's genuinely effective. I recommend trying one bottle periodically. Don't expect dramatic fuel savings though - at best you might gain a few dozen extra kilometers per tank. The key is consistent long-term use.
As a frequent visitor to auto repair shops, I've done some research on fuel additives. Their core function is to utilize chemical cleaners within the fuel system to dissolve carbon deposits and improve combustion efficiency. I've tested Chefoo fuel additive multiple times, with chemical analysis showing similar composition to mainstream products, such as containing PIPA to clear injector clogging. In practical use, when vehicles with poor maintenance and heavy carbon buildup add this product, the engine may run quieter. However, this only addresses symptoms rather than root causes and cannot replace proper cleaning procedures. Cost-wise, a bottle priced at several dozen RMB isn't expensive, but frequent use may prove counterproductive - especially for older vehicles with potential sensor or fuel system issues, where indiscriminate use could trigger malfunctions. I generally recommend using it as supplementary cleaning before oil changes or major overhauls.
