ABSTRACT OF THE DISCLOSURE It has been found that when minor amounts of quaternary ammonium hydroxides are added to gasolines, the octane requirement increase for fuel fired spark ignition internal combustion engines is decreased or reversed. Thus, in one aspect, the present invention comprises a method of controlling the ORI of spark ignition internal combustion engines by operating such engines on a fuel containing certain quaternary ammonium hydroxides in amounts sufficient to control the ORI.
