Re: Leaded fuel

If you can afford the AV gas, 25% is probably plenty if added to non-ethanol gas. Any benefits of leaded fuel could probably be realized by blending 25% Avgas to every other tankful of ethanol-free non leaded. Concerning octane, as I understand it, adding a small amount of lead additive to non-lead raises octane substantially. Higher concentrations provide diminishing effects. Exactly how it affects non-lead that is already fairly high in octane may be different.
