If the final boiling point of gasoline is too high, can adding light materials such as C5 or naphtha and mixing them lower the final boiling point?

If the final boiling point of gasoline is high, by adding light materials such as C5 or naphtha and mixing them, will the final boiling point decrease? victory: :hug:
Thank you all; I appreciate it that you can answer my questions
Do you mean that adding light materials to gasoline with a high final boiling point will not affect the temperature of its final boiling point?
Personally, I think the initial boiling point will decrease, while the final boiling point will not.
If the boiling point of gasoline is very high, can light materials be added to it for mixing in order to lower it?
In my opinion, gasoline with a high final boiling point can be reprocessed to obtain gasoline with a lower final boiling point.
The answer given above is also incorrect; if the price cannot be reduced, then where does the gasoline in the market come from? The dry points of various gasoline components produced in refineries vary; they can be high or low. For example, the dry point of reformed gasoline is over 210, while that of C5 is around 70. The reason is that the dry points are incompatible with each other; therefore, in principle, those dry points cannot be reduced. However, after thorough mixing, the testing instruments can measure multiple dry points at once, and the final average value is obtained as a result.
The final boiling point (dry point) of gasoline specified in the vehicle gasoline standard GB17930 has always required to be no higher than 205°C since before Standard I; any value above this limit renders the product Unqualified. Mixing light components only affects the vapor pressure, initial boiling point, and 5% and 10% evaporation temperature points of gasoline products, with almost no effect on the final boiling point. If the dry point of the gasoline distillate is higher than 205°C, distillation separation must be repeated to remove some of the heavier fractions so that the dry point meets the requirements.
No, the light components have a low boiling range, so they have no effect on the boiling range of the tail fraction
Looking at the addition ratio, if it is small, its effect on the final boiling point can be ignored; if the ratio is high, the final boiling point temperature will decrease
