3. What Advantage will I gain from reading this FAQ?

This FAQ is intended to provide a fairly technical description of what 
 gasoline contains, how it is specified, and how the properties affect the 
 performance of your vehicle. The regulations governing gasoline have 
 changed, and are continuing to change. These changes have made much of the 
 traditional lore about gasoline obsolete. Motorists may wish to understand 
 a little more about gasoline to ensure they obtain the best value, and the 
 most appropriate fuel for their vehicle. There is no point in prematurely 
 destroying your second most expensive purchase by using unsuitable fuel, 
 just as there is no point in wasting hard-earned money on higher octane
 fuel that your automobile can not utilize. Note that this FAQ does not
 discuss the relative advantages of specific brands of gasolines, it is 
 only intended to discuss the generic properties of gasolines.
