Changes In Gasoline IV

As ethanol use expands and enters new markets, automobile service technicians may have questions that need addressing about ethanol and other fuel quality issues. Changes in Gasoline IV - the Auto Technician's Guide to Spark Ignition Engine Fuel Quality ¹ provides service technicians with the information they need on new fuels and gasoline quality as it relates to vehicle performance and driveability. The manual also includes information on power equipment? and recreational engines?.

Changes in Gasoline IV was produced through an educational grant from the Renewable Fuels Foundation? and is being distributed by the Renewable Fuels Assocation?.

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. 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?. 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?, or EISA?, further increasing the renewable fuels requirement. As such, the transportation fuel landscape is poised for another series of changes.

The manual focuses on the auto technician’s areas of interest and covers current topics. A new chapter on flex-fuel vehicles or FFVs and E85 has been added to meet the need for servicing of the growing number of vehicles capable of using E85.
