Can BP Ultimate 95 Really Clean Carbon Deposits?
2 Answers
BP Ultimate 95 cannot clean carbon deposits. However, it can reduce the formation of carbon deposits. Using 95-octane gasoline can lower the likelihood of engine knocking and slightly improve engine performance. More relevant information is as follows: 1. Differences between octane ratings: Gasoline with different octane ratings has varying levels of octane values. 95-octane gasoline has a higher octane value than 92-octane, and 98-octane gasoline has a higher octane value than 95-octane. 2. About octane values: Octane values enhance the stability of gasoline. It must be mentioned that there is an abnormal combustion phenomenon in engines called knocking. When the engine is in the compression stroke, the piston moves upward to compress the air-fuel mixture. As the piston compresses the mixture, the pressure and temperature of the mixture increase. If the gasoline's stability is insufficient, the mixture may ignite spontaneously before the spark plug fires, resulting in knocking.
I think BP Ultimate 95, as a fuel additive, can indeed help a bit with carbon deposit cleaning since it contains detergent components that dissolve some dirt in the intake or fuel injectors during operation. I've tried similar products myself, and they work decently with minor engine carbon buildup, but they're completely ineffective for severe cases—especially in older cars where they might only clean the surface layer. Don't expect it to be a cure-all; the actual cleaning rate depends heavily on engine type and driving habits. I recommend new car owners first try low-cost methods while developing the habit of using higher gears to rev the engine, letting it heat up and naturally burn off some deposits. Prevention is key—choose better-quality gasoline and replace the air filter regularly. If real issues arise, get a thorough professional inspection immediately instead of relying solely on additives.
