We use engine simulations, a review of experimental data, and drive cycle simulations to estimate the reduction in fuel consumption associated with using higher-RON gasoline in individual vehicles. Lifecycle CO 2 emissions and economic impacts for the U.

LDV fleet are estimated based on a linear-programming refinery model, a historically calibrated fleet model, and a well-to-wheels emissions analysis. We find that greater use of high-RON gasoline in appropriately tuned vehicles could reduce annual gasoline consumption in the U.

Adoption of a RON standard in the U. Refinery model parameters, detailed lifecycle sensitivity case results, and files needed to replicate the refinery simulations.
