Can riders who have used Anceaux engine oil talk about the effect after use? Is it worth using?

I use Anceaux, which has run more than 5,000 kilometers so far. To put it simply, the reaction speed of the accelerator pedal is obviously faster and the sound is much smaller than before! I feel almost frustrated, both of them. If the fuel consumption is higher than that of the fourth son, it is not bad on the whole, and I plan to use it all the time.
