"U.S. Gasoline Requirements"

I dunno what any of the
 

I dunno what any of the stuff means besides ethanol and mtbe, :p, can you post a glossary or somepin?

Does anyone know what all of
 

Does anyone know what all of these acronyms mean?

acronyms
 

I know a few:

RVP = Reid Vapor Pressure A high reid vapor pressure helps starus in cold weather, but produces smog in summer.

RFG = Reformulated gasoline (for lower emissions)

Defined...
 

Federal Reformulated Gasoline: Also known as RFG. The 1990 Clean Air Act required the nation's most polluted metropolitan areas to sell a special blend of gasoline during summer months in order to reduce the emissions of ozone forming volatile organic compounds (VOCs) and toxic air pollutants. The regulations require specific fuel content levels for oxygen, benzene and aromatics and set performance standards for nitrogen oxides, VOCs and toxics. Requirements vary by region but generally terminals are required to sell RFG beginning May 1; retailers must sell RFG beginning June 1.

CBG = Clean Burning Gasoline

This link provides loads of info, including demand for gasoline PER month!

According to the Exxon map, in the LA area I get "CA OXY CBG" gas. I can't find a good definition for this gas. I assume it is cleaner burning. How does it compare in terms of energy content? Am I getting a gas that is suited for "low mpg" or "high mpg"?

Thanks,

Maybe this (partially?) answers my question :

I live in the all BLUE state!@!!
I am surprised that Texas is still using MTBE.

Only exxon could get you an energy content value on that fuel. I've searched for hours and could not find anything on the net.

Actually, I've called Shell before, they seem like they are easier to get hold of, and I'd guess that they could answer that question to a point. They test all the other manufacturers fuels every 10 days or so.

I would guess, that the fuel is more suited to lower mpg tho.

Around here, in the very belly of the petrochemical industry, all the pumps say 10% ethanol. I don't think we actually get MTBE in our gas anymore.

CA OXY CBG is oxygenated with ethanol, so it will have a lower energy content, and has a higher vapor pressure than oxygas with MTBE, so it also produces more VOC emissions from storage and fueling operations...
