Fuel additives for a 1925 sedan

[Guest land1925]

Hi

Ijust purchased a 1925 dodge brothers sedan.

wondering if I need use a lead additive for the fuel?

NO.

Is "No" kind of the short answer? I agree that we probably don't drive these cars enough to incur the valve (seat) damage caused by the lack of lead in today's fuels so unless you have rebuilt the engine with hardened valve seats its not a bad idea to use an additive. Am I wrong?

The engine rebuilder who did my '28 model A (his only business) uses hardened seat on all his rebuilds...but then again he drives his car all over the northeast.

I have put over 15,000 miles on my 25 without an additive and haven't had any problems

There was no lead in the fuel in the 20's. It was added when higher compression was added.

You don't need lead but a little kerosene might help. No kidding.

This subject has been thoroughly debated in this thread. It will tell you more than you want to know about the correct fuel for your car.

Rusty,

I just read the thread you suggested. It was very enlighting, and long, but still interesting.

Thanks.
