<VV> Higher Octane Fuel

[henry kaczmarek]

Hi Bob
This comes up from time to time.

The short answer is that you're cheating the government of taxes when you 
put AV gas in a car.  If you cheat on your income taxes as most Americans 
do, though they won't admit it.... it's not nearly as large a deprivation of 
your cash to the government.

As long as it's going into a vehicle that is off-road (like dirt track or 
other race cars that aren't ever run on the street), or a car built before 
1973, technically you're aren't damaging the environment, or messing up the 
02 sensor and converter.

Are you breaking the law?  Since it's something you don't have to do every 
time you re-fuel---a couple times a year is more than enough--I let everyone 
tend their own garden.

Hank
