Terry, I live in Canada but suspect this may be true in the US as well.
Road and transit taxes, among others, are added to fuels sold for use on
public roads that aren't added to marine, farm, and avgas. Use of those fuels
on public roads amounts to tax evasion here so one must be careful what he/she
admits to on public forums I would think. Going back 20 or more years ago,
locals in farm communities around here sometimes had their fuels sampled by
police to ensure they were not running 'illegal' fuel. The color was always
the give-away as dyes were added to all fuels to identify more than just
octane ratings.
I'd be interested to know if this is still the case or if it was ever an
issue in the USA?
Just in case you needed to know, this was sent from
my iPhone.
Here in Dayton (and I
suspect many other areas around the country) I get non-ethanol 100 octane
leaded gas at my local private airport. They just take my
5 gallon container and fill it right out of the fuel truck. No
questions asked. Expensive, but just 5 gallons into a tank of
non-leaded premium really makes my 300F run like a new car. Terry Mc
