aviation gas is stinky...very very very stinky...and if its illegal to run your car on it like it is over here you dont want to be going anywhere near a cop.....i wouldn't like to get fined and are more likely to get impounded straight away..
any trace can also been seen because of the colouration use for av gas...this was a method they used during the second world war to stop thieving of millitary supplies.....this gas also costs more and you are probably likely to see the same results from using an octane booster in your car......Leadfoot
