Excuse me, is Hailong fuel treasure only suitable for EFI vehicles? Can I add Neptune carburetor?

Conclusion For myself, let me talk about my opinion: all engines will inevitably leave dirt on the throttle and nozzle during use. During the use of electronically controlled engine, the fuel injection is related to the throttle opening, and the fuel supply usually increases with the increase of throttle opening. The amount of fuel injected into the cylinder is related to the opening time of the nozzle. The longer the opening time, the more oil is injected. In the process of use, due to the existence of dirt, the computer (ECU) has established a kind of information storage (or learning) for the position of throttle opening and the fuel injection amount of nozzle per unit time in the long-term use process, that is to say, the ECU has taken the current situation of the engine as the default value. After adding additives that can clean dirt, the dirt at the throttle and nozzle will be removed, which will inevitably destroy the default value of ECU. In the process of maintenance, if the throttle and nozzle are cleaned, it is necessary to make a match so that the ECU can learn again, and then the engine can work normally. Another problem is that the cleaned dirt must enter the cylinder with the mixture, and the dirt is non-combustible, so will the cement produced by it be discharged from the engine in time? Otherwise, the piston ring will get stuck.
