I didn't know that about aviation gas.....that's why I like the smell around airports.  I also like the smell of model RC planes. |
If you're smelling it while just around the outside of the airport, you're proabably smelling JetA exhaust.. shich is basically really clean kerosene. the odorant in 100LL is most noticible when you're fueling or just sniffing the tank. It also has a blue colorant added so it can be visually identified.
back in the day we had at least 3 different fuels sold at the airport
80/87 octane which was red
100LL which is blue
140 octane which was purple.
all had a different smell too - only 100LL is left now.
that nifty model engine smell come from the castor-based oil that was used in the 2-stroke mix sold by the hobby shops. You can buy castor-based 2 stroke oil at off-road motorcycle shops. I use it with the 100LL avgas in my Stihl chainsaw.. that smell is heavenly and make you feel like a kid again..
