A new study found that adding isoolefinic hydrocarbons like isooctene and isohexene to gasoline can significantly boost its octane rating, improving engine performance. This "octane hyperboosting" effect was observed when blending these additives, surpassing the octane rating of the individual components. The research suggests that using these additives could lead to better fuel efficiency and allow for higher compression ratios in engines. This discovery opens up new possibilities for enhancing the antiknock properties of motor gasoline, potentially leading to improved overall engine performance.
