    Fuel question (lead substitutes) Kinda carb related, I guess...

    OK, so it's not exactly carb related, but the gas does go to the carb, so it's close. Anyway, I'm finally running my 37 WL and I'm wondering about lead substitutes in the gas. Good idea? Does anyone have any experience with it? I have some stuff that an old timey tractor guy gave me and he says he uses it in all his old machines. I did find a place that sells gas with no ethanol! Just over the state line in WI. IL has only ethanol gas, unless you use the 110 octane racing gas, and a 45 certainly doesn't need 110 octane. Thanks for any input guys!

    For what reason ?

    I read incorrect information like this and have to double check to make sure i didn't inadvertently log onto CNN. Many ethanol free options still exist in Illinois.

    OK, I guess there's only ethanol gas in my local area. Sorry. The reason I thought the additive was a good idea is that originally the motor ran on leaded fuel.

    I know there are modern fuel additives that mimic the cushioning effect of lead, but true lead additives are not available.

    My 1948 Chief runs fine on any kind of modern gas. My 1930 Indian 4 runs like crap, so I sneak into my local airport and buy 100 octane low lead gasoline. I mix 2 gallons of unleaded with 1 gallon of the 100. It runs cooler and runs great.

    If you can buy from a local airport as mentioned above. I'm not a 100 percent sure that it wasn't fuel additives that eat my tank liner. Things i have but in with my gas have had bad effects on the cream.

    I used Marvel Mystery Oil in the gas (about a shotglass in a full tank, while the nozzle is pumping to mix it well) on my 45, keeps the intake stems and upper walls wet. In theory it reduces octane (any oil in the chamber does) but didn't give any bad signs. May color some plugs, didn't see anything.
    Probably does nothing for the seats, but with low spring pressure and low RPM they're pretty durable.

    Thanks guys. I've also heard of guys running Marvel in the fuel. I always thought that lead somehow lubricated or protected the valves. I don't remember where I heard that or if I dreamed it up.
