• Introduced novel HyperFuel-95, −98, −100, and −102 blends with renewable additives. • Applied MED as a gasoline additive for the first time via methoxylation technology. • Evaluated physicochemical, volatility, and antiknock properties of new blends. • HyperFuel series achieved sustainable, low-carbon fuels with superior performance. The shift to low-carbon energy systems has spurred the development of sophisticated gasoline formulations that blend traditional petroleum components with renewable additives to enhance fuel quality and ecological performance. The first successful development of new hybrid low-carbon, environmentally friendly, high-octane gasoline formulations—HyperFuel-95, HyperFuel-98, HyperFuel-100, and HyperFuel-102—is reported in this study. These innovative fuels were created by combining standard petroleum-derived ingredients like gasoline Fischer–Tropsch (GFT), reformate, and light straight-run naphtha (LSRN) with renewable gasoline additives like isopropanol and methyl ester of dimate (MED). The first use of MED, which is made by methoxylating isohexene (dimate), as a gasoline additive is noteworthy. To guarantee adherence to strict fuel quality standards, the study methodically assesses the effects of various formulations on important physicochemical features, with a focus on antiknock performance, hydrocarbon composition, and distillation behavior. Vapor-liquid ratio temperature, vapor lock index, and drivability index were computed using experimental data to evaluate fuel volatility properties better. A base commercial gasoline made from reformate and fluid catalytic cracking (FCC) streams was used to compare the resulting blends’ performance. The effectiveness of blend components was ranked as follows, and the results showed a definite improvement in antiknock performance: MED > reformate > isopropanol > GFT > LSRN. While preserving favorable volatility and combustion characteristics, the addition of MED and isopropanol greatly increased octane ratings. The findings reported that HyperFuel-95 exhibited the lowest drivability index (455.25), while the index increases progressively with higher-grade fuels, reaching 486.2 for HyperFuel-98, 497.5 for HyperFuel-100, and peaking at 504 for HyperFuel-102.
