Add fuel or fuel tank first

I believe that many car owners have been recommended by the gas station staff when they refuel at the gas station.Fuel treasure, also called fuel additive, can clean up the carbon deposits generated by the engine and protect the engine.Then weWhen refueling the fuel tank, should the fuel tank be added first or the fuel tank first?

When we add fuel oil treasure, the correct order should beAdd fuel tank first, then gasoline.This can make the fuel treasure that was first filled into the fuel tank under the impact of gasolineMix well,So as to achieve the best use effect.

Then, when our vehicles are new, do we add fuel tanks? In fact, it is not necessary. Because the new car engine is in good working condition and short-lived, carbon deposits are basically not generated, and the oil in the gas station itself contains certain fuel additives, so we do not need to give the new car Add fuel treasure.andWhen the vehicle has reached a certain number of kilometers and the engine has a slight jitter due to carbon deposits, add the fuel treasure at this time to maximize the value of the fuel treasure.
