Going out on a limb here but seeing it was a beautiful day out and you specify a chevy camaro but not what year, this "may" have been a hot rod, that "may" have had a power adder on the vehicle, say like nitrous! Even though nitrous is not flammable the car owner may have mentioned it as a precaution. Again, I am TOTALLY speculating here, but it's where my head went to after reading the article.
