Lead additive

BradKaeser · Jul 22, 2015

I just purchased a 60 Ford 641 with a gas engine. Do I need to run a lead sub in the fuel?

Only if you like giving $$ to snake oil salesmen.

All fords left the factory with hardened exhaust seats,

Tetra ethyl lead was an octane modifier by design anyway..

( so is ethanol..)

As said only if you want to waste your $$ on something that does nothing. As a matter of fact it does not even have any lead of any sort in it

I would not add the lead additive to your fuel.

Years ago my local co-op offered gas with lead for older tractors, I bought some for my Ferguson,

what I did not realize was that when my tractor motor was rebuilt they used the more modern valve guides that did not need the lead additive.

Long story short: in short order the motor head seized up, had to have head rebuilt.

Do not use the lead additive.

Not sure about the Pre WWII fords, but by the middle 40's Henry knew lead was going to get banned.. Hardened seats standard in NAA and after for sure...

The only stuff you can buy these days that contains tetraethyl lead is 100LL (low lead) avgas. Anything else is snake oil.

Your tractor ran for over 30 years with leaded gas. Its valves have all the lead they'll ever need.

Hardened exhaust seats in all 39+

Hard intakes on most, except wartime 2n.

Tel was a spark knick, ping inhibitor, anything else it did was beside the point.
