They think that it will help their car. In reality, the higher octane gas is for high compression engines. Using it in a "regular"engine will result in unburnt gas which will create deposits on the pistons. And a waste of money.

my large town car livery requires premium gasoline, & performs much better when using it. a car 'expert' once told me it uses less rpm, which is easier on the engine. not sue if this is true or not, but i do notice poor performance when using regular gasoline. the cost isnt an issue as much, i make up for it in other areas where i do not spend regularly
