Can mixed xylene be added to 93# gasoline, and what effects does the amount added have on the engine?
Firstly, gasoline meeting National V standards is available on the market these days, so 93# gasoline is no longer available. They are all 92#, 95#, and 98# gasoline. Gasoline already contains a relatively high amount of aromatics; you can check the national standards – it normally contains a certain amount of xylene. As for the impact of adding more pairs on the engine, this question is too vague and broad to answer properly.
Xylene has an octane rating of over 100, and adding it to regular gasoline can help improve its octane rating. However, xylene is an unsaturated hydrocarbon that tends to cause carbon buildup when burned; its concentration should not exceed 10%. As mentioned earlier by a user, gasoline already contains a certain proportion of aromatic compounds, and too high a proportion of these compounds can lead to carbon buildup.
