Here, if you are a business, you loose your business license. You will pay 300% of the "supposed" tax lose to the state. You don't know what you are talking about. Sorry, nothing personal, just difference rules in different places.
You don't have to take the tags off your car, put on a ski mask and buy non-ethanol fuel at 3:00 am. Nobody cares about the end user of pure gas.
Taxing authorities care about the production, distribution and retail sale of ethanol/gasoline blends but not the end user.
Non-ethanol gasoline is sold with road tax (state & federal) just like the ethanol blends. In fact, in some states, non-ethanol fuel is taxed at a higher rate than the regular ethanol blends.
Non-ethanol fuel generally costs more because there is lower production and it is often taxed at a higher rate, which is why people don't buy it and why retailers seldom offer it.
Motorcyclists, owners of classic cars, people that drive a sports car only occasionally; all buy non-ethanol gas. They're paying the road tax (sometimes even more road tax), they're not breaking any laws and no one cares.
There's NO NEED to use words such as "cheating" and "Caught" when talking about people buying non-ethanol fuel.
