RBOB
RBOB is a common grade of gasoline produced by refiners in the US.
It gets its name from being a reformulated grade of gasoline ("R") that has tighter environmental specifications than conventional gasoline, and its use is mandated in many urban areas with air quality issues. RBOB is a "BOB" (before oxygenate blending) because it is formulated for subsequent blending with 10% ethanol to form the final gasoline blend that is marketed to end users.
