Astro14 is mistaken. Fact... 100LL Avgas does NOT contain more tetraethyllead (TEL) than pre-1975 leaded automotive gas (mogas) had, it has 1/2 the amount of TEL that premium leaded mogas had and 2/3 less TEL than regular leaded mogas had, so it is truly Low Lead, relatively speaking. The FAA will not allow the use of more TEL than this due to the increased incidence of lower spark plug lead fouling when more TEL is used.
The TEL will NOT harm small engines, all a user will notice is that the spark plug will have to be replaced more often. Keep in mind that ALL outdoor power equipment engines ran exclusively on leaded gas prior to 1975. As far as safety is concerned, a person would have to breath the small engine exhaust running the equipment in close proximity for 10,000 hours to get any kind of measurable lead poisoning from using AvGas, the carbon monoxide they breathed during the time frame would be much more harmful. The big plus is that AvGas doesn't go bad. There is a MUCH bigger risk to the health and welfare of the average individual, and the environment, having to deal with the old pump gas in their equipment and gas can.
I used to purchase and use AvGas in ALL of the machines that I serviced beginning in the fall and continuing through early spring every year. I never had a comeback when I did this, except when a customer who though they knew better than me ran through the tank-full that I put in it and refilled with the old fuel that they had sitting at home (even though I specifically told them NOT to use their old fuel). I insisted that all of my Fire Department customers purchase and use AvGas in all of the small engine machines that they used (like jaws-of-life machines, chainsaws, and cut-off saws).
LOL, thank you! only on BITOG people will get so hyped up about another person using a certain kind of gas! This has devolved into "my friend billybob's cousin's neighbor used avgas and his motor blew and he also said 100 Low Lead is not low lead but 4x higher lead!"
