5. They're describing RBOB

GO to http://www.argusmedia.com/~/media/Files/PDFs/Meth/argus_us_products.ashx and scroll to page 9, where they describe the various gasolines they sell...among them:

83.7-octane Reformulated Gasoline Blendstock for Oxygenate Blending (RBOB)
83.5-octane Conventional Gasoline Blendstock for Oxygenate Blending (CBOB)
87-octane Conventional Gasoline
89-octane Conventional Gasoline
91-octane CBOB
91.3-octane RBOB
93-octane Conventional Gasoline

This is the thing they are not telling you: in most of the country, RBOB is exactly what goes down the pipeline, and there are advantages to doing it this way: instead of there being a separate pipeline for every brand of gasoline, there's one big pipeline and the local gasoline distributors add their own company's additive packages. (Incidentally, if you want 87-octane non-ethanol gas, they need only mix 40 percent of 91.3-octane RBOB with 60 percent 83.7-octane RBOB.)
