Finding Gas Higher Than 90 Octane In Alaska Is Oddly Hard (here Are Some Theories Why)

Alaskans person wondered for years why they can't find state higher than 90 octane. Oddly enough, we can't find 1 nationalist acknowledgment of this limit by anyone successful nan lipid manufacture aliases immoderate authorities agency. Yet, nan headdress of 90 octane is real. Even weirder, nan closest point we could find to a news root that comments connected this were quotes successful aggregate forums from an article that was supposedly published successful 2001 successful a publication called Technobabble. But we can't find nan original article, moreover erstwhile searching Archive.org.

The soundlessness from authorities and Big Oil seems incredibly conspiratorial, arsenic if it was ripped consecutive from an "X-Files" episode. The truth is retired there, though, and we deliberation we whitethorn person cracked nan mystery. The reasons for this octane limit, if we're correct, are beautiful mundane. One apt logic has to do pinch Alaska's lack of ethanol production. Ethanol is utilized successful nan U.S. to make astir high-octane gasoline. (Here's a elaborate mentation of why gasoline has ethanol and really it affects your engine.) So this is astir apt a large roadblock successful nan accumulation of high-octane gasoline.

It's besides important to understand Alaska's limitations erstwhile it comes to refining crude lipid into gasoline. While Alaska is 1 of nan apical crude lipid producers successful nan nation, it has only 3 refineries that nutrient gasoline, and astir of it comes from conscionable 1 of those refineries. To adhd nan instrumentality basal to nutrient high-octane state without ethanol would beryllium incredibly cost-intensive.

High-octane state is usually made by blending ethanol pinch a blendstock of refined gasoline. Most crude lipid produces state that is astir 84 octane. Ten-percent ethanol is blended pinch refined gasoline, usually astatine a terminal farther down nan pipeline than nan refinery, to nutrient a higher-octane type than nan blendstock. The 84-octane gasoline is frankincense turned into 87-octane (regular) gasoline. 

To get premium gasoline of 91 octane and above, you person to commencement pinch a higher octane blendstock, for illustration 88 octane. The problem pinch that is that nan higher nan octane, nan little nan magnitude of gasoline that tin beryllium produced. Presumably, that would beryllium a immense obstacle for a authorities pinch truthful fewer refineries, each of which are very constricted successful their accumulation capacity.

The different point is that astir ethanol comes from corn. In fact, each of nan apical ethanol-producing U.S. states are besides successful nan database of apical 10 maize producers. Corn is really difficult to turn successful Alaska owed to its acold soil. So Alaska produces nary ethanol itself, which is why location are nary ethanol stations. Furthermore, ethanol is chiefly transported by obstruction because of nan corrosive effect it has connected pipelines, and location is nary obstruction statement that goes from nan Lower 48 to Alaska. The consequence is state capped astatine 90 octane. That's an rumor for Alaskans who want to bargain definite vehicles, since some engines require premium gas.

Is it imaginable to make high-octane gasoline without ethanol? Yes, location is simply a process called alkylation. Without getting excessively technical, a refinery mixes chemicals to shape hydrocarbons pinch precocious octane ratings. These hydrocarbons are mixed pinch refined gasoline to make high-octane gasoline, besides called alkylate successful this case. So why don't Alaskan refineries conscionable do that? It mightiness beryllium because alkylation requires very costly instrumentality that often costs hundreds of millions of dollars – a prohibitive disbursal for smaller refineries. In fact, according to the Energy Information Administration, Alaskan refineries person zero capacity for producing alkylate.

Alaska produces a batch of crude oil, but its refining abilities are limited. Again, astir of nan state's state comes from its only awesome gasoline refinery, nan Marathon refinery successful Kenai. That refinery's apical capacity is conscionable 68,000 barrels a day, but not each of that is gasoline. Much of it is pitchy fuel, diesel, propane, butane, and asphalt. So it would make consciousness to attraction connected gasoline that powers astir cars. Producing 92- and 93-octane state conscionable whitethorn not beryllium practical, considering nan state's existent refining capabilities.

We want to reiterate that nary charismatic root has travel retired and said that these are nan reasons there's nary state successful Alaska supra 90 octane. But we consciousness these factors must travel into play. If you person a mentation arsenic to why it's truthful difficult to find high-octane state successful Alaska, fto america cognize successful nan comments. And while you're astatine it, publication our station connected when and erstwhile not to usage premium state successful your car.
