The Summer Gasoline phenomenon in the USA

by Graham Email

This article at The Oil Drum explains the backround and practical processes for the creation of the commodity known as "Summer gasoline".
Here in Texas, the Summer gasoline imperative is the need to keep emissions below EPA limits in 96 counties in North and East Texas. The EPA regulations require the use of what is known as "reformulated gasoline" in the Summer months. This has a double impact on what is available at filling stations:

1. The summer gasoline blend may give rise to starting difficulties if used in the Winter
2. The Summer blend has up to 10% ethanol added as part of the attempt to reduce the levels of emissions

For most pilots, (2) is the real issue, since ethanol in fuel attracts and absorbs water, which is corrosive to many fuel system components.
The overall situation is complicated by the fact that there is no legal requirement in Texas for gasoline outlets to report whether the fuel contains ethanol, or how much ethanol it contains. Some filling stations have stickers on their pumps saying "fuel contains ethanol" but many do not.
In Oregon, pilots gained an exemption from ethanol addition requirements for gasoline. The exemption applies to a limited number of outlets selling gasoline for aviation use only. No such exemption exists in Texas, so those of us who might want to try running our planes on road car fuel are SOL in the Summer because the fuel is almost certain to contain ethanol.

Since I dig into stuff once I start reading about it, I have been reading about the fun (if you can call it that) of operating the Wright R-3350 engine.
Here is an interesting posting about this powerplant, by way of a comparison with the liquid-cooled Rolls Royce Merlin.

Redbird 2000-2005

From August 2009 until October 2005 I was a hangar tenant at Redbird Airport (or as it is now known, Dallas Executive Airport). I ultimately moved to Lancaster because of escalating hangar rental rates for no improvement in amenities, and a feeling that the airport was being evolved to cater for business aviation, and us "little guys" were no longer welcome.
When I first told fellow pilots that I was considering renting a hangar at Redbird, I was warned off the airport, with lurid tales of theft of avionics and other malfeasance being produced by way of explanation. When I raised these issues with the rental office, they agreed that, yes, all of those things had occurred, since the hangars had been in private ownership, but the city had repossessed them and was going to ensure that things were run properly in the future. I moved into my hangar, and never had any problems with theft or other malfeasance, although the hangar floors were substandard and the taxiways had been built up through resurfacing, which caused water to drain towards (and into) hangars rather than the other way round.
This article in the Dallas Observer, ironically titled "Deadbird", provides a none-too-flattering history of the malfeasance that occcurred at the airport up to the beginning of 2000. Once again, the race issue is writ large in the history, as the airport amenities became part of the minority business boondoggle mindset that seems to be a perennial fixture in city politics in many parts of the modern USA. Reading this article, one could be forgiven for thinking that Redbird Airport at the time was in some Third World country...

For some time a searchable text file version of CP01-82 has been in existence. Marc Zeitlin has now loaded the remaining CP issues up to his website here.
The loaded files are Adobe Acrobat format and therefore are not text-searchable, but simply having all of the CPs in one place is a very significant improvement. Thanks to Marc and those that helped him.
