Nope. In my situation, I don't care if my fuel smells like castor or grape soda pop, as I don't have any small children around. For those with children, I absolutely agree with the idea of not adding anything to the fuel that might entice a child to take a drink.

But in my situation, I wouldn't have any qualms about adding scent to my fuel. Once I have children, I'm sure my opinion will change.
