I Got the Gasohol/Winter Gas Blues the Root of the Problem
The Newsletter for the Superformance Owners Group April 12, 2015 Volume 9 Number 1 I Got the Gasohol/Winter Gas Blues Gasohol – A Pain in the Gas ethanol boils at a temperature lower than the operating Gasoline is a blend of more than 200 different hydrocarbon temperature of most engines. liquids. Prior to the mid-1980’s, gasoline was blended to work And as any moonshiner can tell you, ethanol boils out of the in carbureted cars. From the mid-1980’s on, fuel injection liquid it is mixed with at the boiling point of ethanol, not the replaced carburetors and the fuel blends changed accordingly. boiling point of the mixture. The problem is that if the gasohol The primary difference is that carburetors meter fuel at gets hot enough, the ethanol will boil and will either flood atmospheric pressure and fuel injection meters fuel at high your carburetor or cause vapor lock in your fuel pump, or pressure. The high pressure allows the use of a higher both. percentage of volatile elements in the blend. Today the proper functioning of gasoline in carbureted cars is no longer included in the gasoline testing standards. That is why those of us with carbureted cars are experiencing increasing difficulties. The biggest change affecting carbureted cars is the increasing use of ethanol as well as the other volatile elements used in winter gas. Until recently I never had gasohol/winter gas problems. In the past couple of years, I have had quite a few. The percentage of ethanol in gasohol around my home has been steadily increasing over the years and has reached a point where it is a serious problem for cars with carburetors. -

Avgas Vs. Mogas in Light-Sport Aircraft
EXPERIMENTER TECHNICALLY SPEAKING PART 1 AVGAS VS. MOGAS IN LIGHT-SPORT AIRCRAFT Upsides and downsides BY CAROL AND BRIAN CARPENTER ONE OF THE MOST requested topics for us to weigh in on is avgas (avi- ation fuel) versus mogas (automotive fuel) in light-sport aircraft. It is important to identify This is also one of the more controversial subjects that makes it very difficult to write an article that is definitive on the subject. the downsides of each type We often get questions like, “What type of fuel should I be using in my light-sport aircraft?” This is akin to the question, “Do these of fuel in order to make pants make me look fat?” Your first instinct should be to change the subject as quickly as possible. God forbid you do elect to engage, you a judgment about how it need to recognize that the conversation is going to morph into many other unrelated topics, and nothing you say is going to be an accept- will impact your airframe able answer. and engine under these Several years ago, we did a two-hour presentation on the subject for the RV-12 fly-in in Bend, Oregon.

Well, that wasn’t type of fuel. So, in reality, it is a matter of very helpful, was it? But that was the point. -

New Information on E85 and Flex-Fuel Vehicles “Changes in Gasoline IV” is the 2009 edition of the ongoing series of “Changes in Gasoline” manuals. The first manual, “Changes in Gasoline & the Automobile Service Technician,” was originally published in 1987. Since that time the multiple editions of the manual have collectively exceeded a circulation of 500,000 copies. The numerous editions of the manual have been necessary due to changes in federal regulations, fuel specifications, and advances in automotive technology. For instance, “Changes in Gasoline” was written shortly after the elimination of lead from gasoline, while “Changes in Gasoline II” was written after passage of the 1990 Clean Air Act Amendments. Most of the requirements of the 1990 Clean Air Act Amendments were implemented by 1995, resulting in the publication of “Changes in Gasoline III.” In 2005, the federal government passed the 2005 Energy Policy Act (EPACT05). This legislation did away with requirements that reformulated gasolines contain oxygen. It also included a requirement that an increasing amount of our transportation fuel be from renewable sources such as ethanol. In 2007 the federal government passed the Energy Independence and Security Act, further increasing the renewable fuels requirement. As such, the transportation fuel landscape is poised for another series of changes. There are, of course, other important developments with transportation fuels, most notably, fluctuating prices. -
