The new site includes the means to quickly determine if a mogas STC is available for your engine and airframe combination. The choice of airplane images on the web site depicts the wide range of aircraft that are covered by Petersen STCs, from the Piper Cub to the Douglas DC-3.
There is a rather clarifying paragraph in the EPA Notice published Nov. 16 that denied a waiver on ethanol blending quotas that was requested by several states, resulting from the effects of the drought on the corn crop this summer. I turn your attention to pages 27-29 of the document, which clearly outlines the changes happening in the gasoline production environment and portends the end of premium unleaded gasoline as we know it:
Mark Wiley of Murfreesboro, Arkansas,who flies a 1963 Piper PA-28-235 Cherokee, contacted your bloggers some months back when his efforts to lower his costs lead him to mogas. Since then he has obtained a mogas STC from Petersen Aviation, installed a simple fuel system next to his hangar, and found a fuel supplier that brings him 93 AKI ethanol-free mogas in small loads. He recently reported on the savings he’s seeing and how he intends to use them:
According to a recent article in the Wall Street Journal, the Paris-based International Energy Agency (IEA) predicts that the United States will overtake Saudi Arabia as the world’s leading producer of oil by 2020. Due in part to the remarkable yields enabled by hydraulic fracturing (fracking) and directional drilling, [Read more…]
The northeastern region of the U.S. is one of the RFG (Reformulated Gas) Areas where the EPA dictates the use of an oxygenate in gasoline to lower carbon monoxide emissions. In the U.S., ethanol is the most common oxygenate, in addition to it raising a fuel’s AKI (Anti-Knock Index, commonly called octane) rating by about 2-3 points. Oil companies, realizing a means to lower the cost of refining, typically deliver a sub-octane fuel known as BOB (Blendstock for Oxygenate Blending) to fuel terminals in there areas, where ethanol is then blended into the fuel. This is the reason that in RFG areas one has difficulty finding ethanol-free fuel, as can be seen by comparing the RFG map to Pure-Gas.org map.
Without ethanol, BOB’s AKI rating is only 84, below the needed 87 for the cheapest Regular gas. BOB is not a legal “finished” fuel until ethanol is added. Thus, any disruption in the supply of ethanol (such as a storm or ethanol rail car explosion) will affect an oil company’s ability to provide finished gasoline. Prior to Sandy’s making landfall, this CNBC article summed up the danger simply: “Bottom line — if we run out of ethanol we run out of gasoline.”
Evidence of the continued worldwide expansion in the use of lead-free, ethanol-free mogas in general aviation comes from this report from Israel. Haim Zaklad, a private pilot there, recently requested details on our study of the FAA’s aircraft registry showing that over 80% of all piston engine aircraft could operate today on lead-free, ethanol-free mogas. He described the recent successful action by pilots in his country to gain approval of the Petersen mogas STCs from Israel’s Civil Aviation Authority:
In news that is sure to send shock waves throughout the ethanol industry and the EPA, one of the world’s largest oil companies is shelving plans to produce so-called cellulosic ethanol from non-food plants such as wood chips and switchgrass. As described in an article from the Wall Street Journal, “BP PLC Thursday said it is ending plans to build a commercial-scale cellulosic-ethanol plant in Florida, saying it instead will focus on research and development.”
Commodities, by one definition, are “mass-produced unspecialized products.” Typical traded commodities include grain, coffee, sugar, pork bellies, feeder cattle, industrial and precious metals, natural gas and oil. They are produced worldwide in enormous quantities, resulting in most cases in far lower real costs than a century ago when limitations to transportation and political barriers to trade restricted producers to their own local markets.
For many years, aircraft manufacturers have made use of some of these commodities, [Read more…]
With vehicle fuel prices surging across the country, pilots are also feeling the pain at the airport pump, with the price for a gallon of avgas averaging more than $6 in every region, as reported by the website 100LL.com. According to statistics reported by AirNav.com, average prices for Jet-A remain about 50 cents lower, while mogas is a whopping $1.50 less than avgas.
